[Bug 15925] New: World of Warcraft: Extreme FPS drop since 3.0.2

http://bugs.winehq.org/show_bug.cgi?id=15925

Summary: World of Warcraft: Extreme FPS drop since 3.0.2
           Product: Wine
           Version: 1.1.7
          Platform: PC-x86-64
               URL: http://www.worldofwarcraft.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

At first it felt like a normal evolution of the game's hardware requirements,
but due to a LOT of recent feedback from WoW players under wine, it seems like
something doesn't work on Wine's side.

Since the expansion patch Echoes of Doom, World of Warcraft lost at least 30
fps in crowded areas (shows a lot in battlegrounds and raids), and over 15 fps
in completely empty areas. The new shadow engine is disabled. Turning all
details and other effects off has very little effect on the game.
The new (bug 14975) screenfog effect (ffxSpecial) is disabled. Existing
configuration hasn't been changed.

Enabling or disabling GL_ARB_vertex_buffer_object shows no obvious difference
(feels slightly faster when disabling).

No relevant output is given in the terminal. Downgrading to wine 1.0, 1.1 or
1.1.3 (all three worked quite fine before) doesn't make any difference.

I've got an nVidia 8800GTX, using the 177.80 drivers, and having the same
problem.

It may be irrelevant, but every report I've seen about this so far is from
users with nVidia cards.  Any ATI users out there who can report in?

I've somehow gotten it working with much higher fps (from 5fps in Black Temple,
up to 40-80 now) after a reboot and tweaking multiple config options
(Multisampling and fullscreen glow mostly).

Attached is my Config.wtf. Can you try this?

I gave Adys' configuration a try and still have very poor framerates (7-15 fps
in battlegrounds, opposed to 60 fps in Windows on the same hardware). Running
wine-1.1.7 on Ubuntu 8.10 with NVIDIA UNIX x86_64 Kernel Module  177.80 on a
GeForce 7600 GT. The Pixel Shader option in Winecfg doesn't seem to have any
effect.

This is not really a regression, since the problem is related to a new version
of the program, not of wine. Blizzard did a serious overhaul of their graphics
engine for the new expansion, and this code has just gone into the live version
in preparation for its release.

Since 3.0 came out, I have upgraded from a geforce 7900gs to a 9800gt, with
essentially no effect on framerates. What I would like to see, however, is if
someone has compared wine framerates with windows framerates when the windows
version is running in opengl mode as well (since the slowdown could be in
blizzards opengl interface, not in wine)

Does your fps hold reasonably in highly populated areas? (such as Ironforge or
Shattrath)

Tested FPS in higly populated areas as asked ( sorry i didn't do'it before) and
the reult is:  Orgrimmar - 17-20 fps and latency 38 ms ( so is not caused by
latency) / Shattrath 15-20 fps latency 43 ms .At this point i can only say that
i confirm the bug.

Could users having this problem try this?

- Go in winecfg, graphics and disable pixel shaders
- In game, go in graphic options and disable Triple Buffering as well as Full
Screen Glow
- Eventually, try disabling the GL_ARB_vertex_buffer_object extension with
http://www.wowwiki.com/Wine_(software)#Registry_Tweak_for_FPS_Boost

For me, it fixed this bug as well as bug 15926 and bug 15927

None of those suggestions had any effect for me except the registry tweak,
which actually had a negative impact on my framerates.

> Could users having this problem try this?

I had no effect from shaders, glow or triple buffering (though I have vertical
sync disabled for performance anyway). I had a negative effect from the
registry change to disable the GL_ARB_vertex_buffer_object extension.

In shattrath I'm holding 9-14 fps with all of the suggestions above, 15-20 with
all of them except the registry change.

I have also tried changing back to Wine 1.1.5, with and without the above. In
1.1.5 I still have low framerates, but not *as* low. It's most pronounced in
Alterac Valley, where I had 7-10 fps in 1.1.7 and 15-20 in 1.1.5.

Ah, that's an important point. we should add our wine versions to any data
we've posted.. 1.1.4 here, since it's what's marked stable in gentoo atm. I'll
try out other versions and see what info I can get.

Following the instructions on the
http://www.wowwiki.com/Wine_(software)#Registry_Tweak_for_FPS_Boost dropped my
fps from  17-20 in Shattrath to 4-8fps (witch make the game almost impossible
to play ).
Wine 1.1.7 
Restored previous settings.

I get really low frame rates 15-20 and I have had realy bad shuttering. It was
so bad in instances that I could not play. I changed to -OpenGl on my wine
wow.exe line and the shuttering went away. I still get lousy performance out of
my GeForce 8700GS 512MB Vram and my AMD 64 x 2 4200+   It's worse where I see
for long ranges like the top of the aldor sanctuary, however adjusting the
graphics settings don't do much for the frame rates. So I get crappy frame
rates whether I actually see far or not.

Only confirming.

Went from a reasonable 20 - 100 to 2.0 - 10.

Lowest I saw was 1.1 in MH .... Yes, that's ONE point ONE. It was really scary.

Can confirm the fps drop.

Using 32Bit Debian with amd quad phenom - NV8800GT/8600GT (with 177.80 driver)
Wine-1.1.7 and 1.1.8. (Verified on 2nd system with amd dualcore and NV7600/wine
1.1.7). Wine compiled with gcc-4.3 and target optimization für amd cpu's.

10-20 fps in OpenGL mode (Shat and other crowded places).

Also, changing ingame graphic options doesn't solve the problem.

Sometimes i also see the stuttering as noted above.
My (old) trick to reduce stuttering in WoW in a multicore setup (=> pin the
wow-processes/threads to a dedicated CPU-core (=>set cpu affinity with
schedtools)) won't work here and has nearly no impact in this situation. (As
opposed to pre 3.0x version).

if there's anything i can do (eg. compile with special options, debugging
sessions...etc... tell me and i'll volunteer)

btw: wine can't fix BETA quality software - only trying to reduce the impact - 
salute to all wine developers, your doing a very good job :-)

I've tried compiling with different levels of optimization, though now I'm
faced with crash after crash in little to no playtime. I'm going to get a new
graphic card either way.

Disabling shaders definitely helps a lot though, the fps drop is minimal since
then. At least for me...

I'm running 8800gtx with the 177.80 drivers, 2 gigs of ram, AMD 6400+ dual core
running under opensuse 11 and Wine 1.1.8 in OpenGL mode(D3D crashes the game).
I've noticed a big FPS drop with the new patch. BT was perfectly playable with
about 40-60 fps during intense boss battles and trash. After the patch it chugs
along at 15 fps, which is playable its just hard on the eyes. Sunwell, Battle
for Mount Hyjal, and Serpentshrine Cavern also surfer.

Also since the time I've been in Northrend (only lvl 72 ATM) when inside
Warsong Hold I get decent FPS but it jitters every 2 seconds. Enabling or
disabling GL_ARB_vertex_buffer_object shows no obvious difference ether.

When its all said and done, I confirm this bug.

I recently installed the latest TryWoW.exe on windows and then copied it to
Linux. I got it working with opengl and some extra settings like 'fxGlow 0'. I
am on a laptop with an ATI Mobility Radeon X700 chipset and the framerate is in
800x600 around 10 fps with all effects low. I have tried many different
settings in wine.. Pixelshader off, sound off, all settings, fxGlow 0,
fxSpecial 0, etc.

On windows I can run the game in 1280x800 at a 30 to 40 fps. I will check if I
can run the game on Windows in opengl and see if that has a bad performance
too.

So I think this problem is not only limited to Nvidia chipsets.

Tried to use config.wtf posted by adys on an Athlon64 3400+ & radeon x1900. 
Significant framerate improvement (from 5-10 fps in IF, to  25-40).  Minimap
will not display while inside and something seems to be triggering some tearing
a few seconds into the game.  Running ubuntu intrepid and wine 1.1.9.  Tearing
seems to be related to the minimap error as it will only occur when
transitioning indoors.

I've now tried running Wow in OpenGL and D3D mode on Windows XP. My experience
is that while both modes provide higher framerates than Wine, D3D is much
better performing for my hardware in Windows than OpenGL. In particular, I've
seen framerates of:

(all in the horde stronghold of Alterac Valley)
Windows XP, OpenGL: 29 fps average
Windows XP, Direct3D: 51 fps average
Wine 1.1.5, OpenGL: 14 fps average

Could you try the new nVidia 180.11 beta drivers? I've had *huge* performance
improvements with them.

If you're faced with further crashes with those beta drivers, please have a
look at bug 16311.

I think when you do this, you will see that windows suffers a bit using onenGL
framework..  The problem is not so much windows versus wine than it is DirectX
support versus OpenGL support of WoW.

Do not expect wow to run as good in wine as it does on windows unless some
extreme progress on DirectX support on wine is made.  Blizzard

I'm running kubuntu x64 bit, Geforce 8800-GTX using 180.11 NVidia drivers.  The
new beta drivers did actually provide a lair level of inprovement in overall
gameplay, but in "pretty" areas where there is plenty of lighting, shading, and
density to draw, they still suffer on the OpenGL platform far worse than they
would on DirectX.

Blizzard would have to almost re-write the openGL extensions of its game to
truly fix the issues we are experiencing, so I think there is only so much
improvement to yield by new NVidia drivers or new versions of Wine.  Your best
bet?  Better DirectX support in wine...

I tested the game in windows using opengl and I cannot play the game decently
as I get opengl corruption in the 3d characters but that is probably due to old
catalyst 7.12 drivers I have on this laptop using the omega drivers.

I have 1Gb RAM in my laptop and in Windows WoW runs perfectly fine with all
details on low (the laptop is not the best). But to have a decent frame rate on
Linux and Wine 1.1.9 I had to upgrade to 1.5Gb RAM. Running Kubutu 8.10 (KDE4)
and Wine 1.1.9 and WoW 3.0.2 is too much for 1Gb of RAM. So if you experience
stuttering when walking around but the framerate is okay if you don't walk and
don't have other players around it might be you need more RAM.

The only other problem I have is that when entering a cave or a home with the
minimap turned on, that I get random frames on the screen and text is not
displayed correctly before. But that is a diferent bug I think.

I used the config.wtf of Adys to get it running properly in 1024x768. In
windows I can do 1280x800.

Some updates on this - I currently get NO FPS issues, but I do get some
crashes.

As of nVidia 180.11, in OpenGL mode I get *great* FPS now - maybe 3-5 less than
in windows OGL mode. All settings maxed, shaders, bloom, 1680x - no advanced
shadows (which arn't supported in blizzards OGL engine yet). Loading from disk
can be a little slower, but other than that this game runs VERY well on linux.
The disabling vertex buffers doesn't seem to do anything anymore.

The only problem for me now is crashes - Every now and then, especially
reproducible in certain areas of the game world - I'll get massive graphical
corruption. Polygons everywhere, textures all wonky, 2FPS. This'll last for a
few seconds before a segfault. However, I am more inclined to believe this is
an issue with nVidia's newest drivers, which suffer from some internal-state
degradation issues for me in Non-wine programs, and generally are not very
release quality.

Also, something WoW/NTFS-3g is doing makes running this game off an NTFS
partition load/unload *extremely* slow - like 10-20x vs an XFS partition
(though it works fine at full FPS once loaded).

There's been a fair few changes to shaders in recent git commits (post 1.1.10).
Since shaders seemed to be the problem, could this be retested by more users
with last git?

I just compiled the latest wine-git and the minimap doesn't break anymore.
However it does show the minimap of outside the building/cave and not the
internal minimap. No garbled polygons etc.

Good thing is you can play it. I will do some endurance testing later in the
evening.

After more testing it still is not working well. I tested it in other buildings
and it still break. So it is not better.

Running on a E6600 core 2 duo OC'd to 3ghz, 9800GTX nvidia card and 2GB of ram,
getting 60-100FPS out in the open when no people are around, but in
dalaran/orgrimmar/shattrath with 20+ people, or in 25 man raids the FPS drops
down to 5-15. Pretty unplayable.

Using nvidia-drivers-180.11, wine-git from the 11th of december and the
2.6.27-gentoo kernel. Running -opengl (-d3d gives even worse performance).

Confirming that the bug is still not fixed as of the 11/12 wine.git.

--- Comment #37 from Dimitar Panayotov   2008-12-16 11:59:28 ---
Hello guys,

I compared Windows Wow (direct3d) and Debian wine WoW (opengl) and here are the
data:

=== WHAT I DID:

* I copied Windows installation of WoW 100% to ReiserFS harddisk in Debian.

* I removed "Config.wtf" and after that I got my graphic options to full
quality (disabled options: "Full-screen glow effect", "Death effect", "Triple
buffering" disabled too although I never noticed difference with or without
it).

* I use "-opengl" option.

* Pixel shaders are disabled in "winecfg".

* I removed the so-called "registry hack for FPS boost", and I found out its
presence actually impacted my performance, although slightly (4-5 FPS
difference, which is still much in raids). Removing the registry key helped.

=== ENVIRONMENT:

* Debian version: 5.0 (lenny)

* WoW version: 3.0.3

* Wine version: 1.1.10

* NVIDIA driver version: 173.14.09

* NVIDIA videocard: 7600GS (256 MB RAM)

* kernel: 2.6.26-1-amd64

* RAM: 3GB DDR-2 800MHz

* CPU: Pentium D 3.40GHz (dual-core)

=== OBSERVATIONS:

* Inside Dalaran, in front of Alliance bank, staying still and looking at a
myriad of people running around: 13-16 fps (same in Windows)

* Running around inside Dalaran: 12-15 fps (same in Windows, sometimes even
worse).

* Flying from Dalaran to K3 in Storm Peaks: 26-45 fps (Windows hardly ever gets
above 30 fps while flying anywhere in Northrend). Seems to vary VERY MUCH,
cannot really determine what from... still puzzled.

* Walking on ground mount outside K3: 25-50 fps (Windows hardly gets more than
35 in any ground riding at all in Northrend).

* Entering in high speed from outside to inside K3 *always* results in huge FPS
drop: if I was at 45 fps, it drops to 20 fps in a second. I am suspecting
network latency is the issue.

* Flying from K3 to Brunnhildar Village on swift flight mount (and back),
maintaining low altitude from ground (20-30 meters so there are still lots of
details to render): 35-60 fps! Windows gets 50-60 fps only outside Northrend,
like riding in Azeroth or most of Outland. Windows NEVER gets above 40 fps in
Northrend ANYWHERE.

* Ironforge bank: 13-21 fps. Windows can't beat that as well, it tops 18 fps
there.

Something like conclusions:

Debian wine WoW setup works quite well, although the minimum FPS values are
lower than Windows (generally). If Windows varies 20-40 FPS in an area, wine
WoW varies 12-50. Also, as a general feeling, wine WoW seems bit more sluggish,
meaning that entering new areas, quickly diving in populated area etc., gives
you huge drop in FPS very quickly. I suspect the network stack is the culprit
in this issue, but I really don't have the patience to do the necessary
measurements with kernel-level tools.

But in overall, wine WoW is actually more responsive, meaning that when WoW
"sleeps" for a short period because of doing screenshot, entering AH etc., wine
WoW reacts considerably quicker. I blame the kernel resolution timer for that,
but again, cannot be sure.

The last test I did was to try running wine WoW in another computer, far worse
in hardware means, and was amazed to find out it actually held 10 fps inside
Dalaran while lots of people were riding around! Pretty conclusive for me...

So, my conclusion would be that the struggle which wine WoW experiences in most
setups is OpenGL support problems, or huge network latencies in populated
areas. But in the end, think about it -- twice as worse computer compared to
mine performed almost the same in Dalaran. It's gotta be the network.

Hoping to have given you some valuable data. Ask for more if I missed something
crucial.

And finally -- I am not drawing conclusions for another's setups. I also found
that certain options (see above) did improved my performance as well.

Dimitar P.

I have no proof for this, maby just call it a gut feeling; I think the/one of
the reason(s) for the bad performance people are reporting here is caused by
wine+wow not using multiple threads correctly. It spawns them allright, (about
10-15 of them), but only 1 of the threads are at 50% usage, while the others
are at 0-1%.

Considering that WoW is CPU-bound on anything but a very very bad gfx card,
this is going to cause a MAJOR FPS problem, especially in crowded conditions
where addons and stuff is hogging a lot of CPU time.

Something to keep an eye out for when bug 11674 is solved maby?

it seems that the conclusion of bug 11674 is that WoW does not multithread the
rendering code. This has also been mentioned in the WoW official forums several
times over the years; wow currently does not use multiple cores to the fullest
extent.

While I notice the same FPS's posted in the busy areas you mentioned, I have
seen them for quite some time.  I would LOVE to get better frame rates, but
lets do a little reality check:

1) The Game supports OpenGL, but most people who develop in OpenGL will tell
you its done rather sloppily in WoW.  This has been common knowledge for years.

2) The target audience for this game is Windows users.  Therefore, most of the
performance enhancing fixes for the game will be surrounding the DirectX
extensions.

3)  Don't think Running a Geforce 8800GTX-OC or any other nice gaming card
means the same thing in Linux as it does in windows.  Those gaming cards have
unbelievable power when it comes to shaders, but without DirectX you cannot
really unlock that power in your card in a Linux Operating System.  Case in
point, my laptop has an internal Quadro-FX 1600M card and my FPS is almost
double that of my Geforce 8800 in my desktop, both linux based.  Quadro-FX
cards were designed with OpenGL acceleration in mind, Geforce cards were not. 
Ergo, you WILL NOT have the same performance levels from platform to platform.

If you're getting 4-5FPS in a highly populated area, there is likely a fix for
you, unless you are running a ridiculously old card or system.  If you're
getting over 15-25FPS in highly populated areas, and getting upwards of
25-30FPS in non-populated areas, you're doing about the best you're going to do
on a Geforce card with any sort of moderate graphical detail enabled.  If you
want higher than that, my recommendation is to invest in a Quadro-FX card.  In
the long run, if you want to game on linux, you will be happier with it.

Markus,

In my oprofile runs on .22 I did not see a lot of time being used in
HeapAlloc/HeapFree while in "established state" (1/2 minute after loading
game). As I said somewhere else I only see libGL processing.

Do you believe this bug may be have been fixed another way ?
Do you still see this behaviour ?

Update on this bug.

The performance drop is minimal, now. This may be improvements in Wine, or
Blizzard improving their engine, or more likely both. 
Disabling or enabling vertex shader/pixel shader no longer has any visible
impact on the game's performance.

Both in D3D and OpenGL modes, WoW has improved a LOT recently. Running the
180-185.x nvidia driver branch also helps, which may mean the nvidia driver had
some bugs as well.

I think it's safe to close this bug as fixed.

It doesn't seem fixed to me at all. With wine 1.1.24 and nvidia-drivers both
180.60 and 185.18.14 I still get that unreasonable slowdown in crowded areas
(like 4fps in a 25man raid). Normally I have like 50fps.  Can anyone else still
confirm it?

You should first confirm if this is a real bug...

Let me explain:
=> WoW, even on Windows has real slowdowns on crowded cities like dalaran. This
game basically _does_ not scale. These cities are too small, and most of game
cycles are lost in the game code itself (do an oprofile to check it !). Blame
blizzard.
=> The GL drivers on linux are not as performant as windows ones. Bascially
they are not threading command buffer generation. Blame ATI/NV !

Have you tried to dual-boot and test WOW in the same box on windows with
-opengl ? I did not notice that a huge difference myself. Maybe you will...

Truth is this game does not take profit of multicore, has a sub-par (compared
to its DX) GL backend, and that wine does not account for a lot of the cycles
(it is just wrapping some FS and GL calls)

PS: remove the VBO disable flag in regedit if you added any ! That's reducing
FPS by removing access to modern GL interfaces ! What a bad advice...
