[Bug 34011] New: Path of Exile stutters constantly

http://bugs.winehq.org/show_bug.cgi?id=34011

Bug #: 34011
           Summary: Path of Exile stutters constantly
           Product: Wine
           Version: 1.6-rc4
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

When playing the game, any time a new resource is loaded from disk, the game
freezes completely for some time while it waits for the load. Given that the
game is constantly loading things from disk, it makes the game nearly
unplayable in many cases.

Setting UseGLSL to disabled seems to mitigate this.

I can confirm this is a significant problem, as it can render the game
unplayable if you don't have a buddy with to cover you while recovering from a
lag spike.

I will say, however, I loaded the 'Content.ggpk' file from the PoE installation
directory to a tmpfs ramdisk, and symlinked it to the PoE install directory
where it was and this helped, albeit only a little bit. The stuttering was
still an issue.

That single file is about 4.5GB in size and would have contained most of the
game's content data.

problem?

As I've been looking for more information regarding the issue and potential
workarounds, there seems to be a consensus that this is only an issue for users
with AMD/ATi graphics cards.

If that is so, that would make this not a wine issue, unfortunately.

What graphics card do you guys have? I have a Radeon HD 7870 (PCIe).

I have an NVIDIA 550 TI, so it affects NVIDIA too. Setting UseGLSL to disabled
makes the game playable, but even then I often die because of the lag when I
face unique bosses or large group of creatures.

I likewise experienced this issue on a Radeon 7850, using the 13.11 proprietary
drivers. Disabling GLSL made the game unable to open until I deleted my old
production_Config.ini so it would reset my settings. Then the game would load,
but the main menu background was black, and any attempt to change any of the
display settings made it freeze. So I was unable to test if it mitigated the
issue for me.

My understanding is that this isn't "when a new resource is loaded from disk",
but rather "when a new effect is drawn, and the game suddenly goes off and
compiles a new shader script to HLSL, which Wine then has to compile to GLSL,
which the driver then has to compile to its own internal representation."

Why that's such an issue, I have no idea.

--- Comment #11 from Screwtape  ---
Earlier this year at FOSDEM, one of the Mesa developers gave a talk called
"Three Years' Experience with a Tree-Like Shader IR":

http://video.fosdem.org/2014/H1301_Cornil/Saturday/

...in it, he talks about how terrible Mesa's GLSL compiler and optimizer are,
and explicitly mentions that it tends to cause problems for games run under
Wine. Apparently, Direct3D treats vertex and fragment shaders separately, and
you can swap them in and out any time you like, so games tend to do that a lot.
In GL, vertex and fragment shaders are considered part of the same shader
program, so when a game swaps out one fragment shader for another, Wine has to
recompile the new combination of vertex and fragment shaders, which is more
expensive than what Windows does. On top of that, Mesa's GLSL compiler is very
slow and inefficient, and the speaker actually mentioned
stuttering-while-approaching-a-boss as a common symptom.

So I suspect there's nothing Wine can do about this particular behaviour.

This bug is even more important than in the past. Why? Because prior to Path of
Exile 1.2.2, users could disable GLSL and experience relatively smooth,
glitch-free gameplay.

After the Path of Exile 1.2.2 patch, users with GLSL disabled still experience
smooth gameplay, however, Path of Exile now has a slowdown issue on mana use
alleviated only by using a very recent wine version (I'm running 1.7.27, the
latest version available as of this writing). The consequence of using a recent
version of Wine is that we get some unacceptable GUI glitches that essentially
blank out large portions of game screen. Here is an example screenshot:

http://i204.photobucket.com/albums/bb130/7h645764n57/poe-issue_zps12561cf6.j...

The only way things would be perfect is to fix the stuttering bug that this
page is about, so that users could run Path of Exile as intended, with GLSL
*enabled* without undue FPS drops when new graphics resources (e.g., spell
effects) are rendered.

I know it will be a lot of work to optimize GLSL under wine. Hopefully someone
is working on it.

Consistently reproduced on different systems. Example:
Ubuntu Linux 14.04 LTS 64-bit
Intel G3258 (2x 4.1 Ghz), Also Core i3-4360 3.7 Ghz
8 GB DDR3 RAM
Video Card: Nvidia GeForce GTX 750 Ti with 2GB memory
Nvidia proprietary driver 337.25 (all versions including latest beta tested, no
difference)
Screen Resolution: 1920x1080 (1080p), Path of Exile runs in full screen mode 
Fast SSD hard drive

Hi Andrey, Path of Exile is now perfect (except the fonts) with
1.7.27-PathOfExile-1.7.27 via PlayOnLinux and an Nvidia card with GLSL
disabled. ATI just does not work with GLSL disabled. Must be something with
their drivers, been that way forever. Looks like you will have to spend $50
like I did for an Nvidia card to play Path of Exile properly.

There was some addition into wine code recently that fixed a regression bug
which had Path of Exile game mentioned.

It would be worth to retest against 1.8.rc1

I gave it a test, but performance did not fix the stuttering. It did improve
any flickering/corruption issues that were coming up per that bug, though.

Should add that if I switch over to wine-staging and use CSMT performance comes
way up overall but the stuttering is still a major problem.

Current relevant specs:
Nvidia GTX 260 w/proprietary driver v. 358.16
AMD Phenom II x4 965 3.8 Ghz
12GB DDR3 1600 RAM
Arch Linux x86_64
wine 1.8-rc1 (and wine-1.8-rc1 (Staging) tested, too)

How about CSMT off with staging? Does it change anything?

With CSMT turned off, performance is identical to vanilla wine.

In both cases, the stuttering behavior reported here is frequent. The only
difference is the average frame rate with CSMT on improves significantly but
frequent frame time spikes are still common. It is still always a problem when
effects/shaders need to be rendered for the first time entering a map.

I imagine this still an issue related to Comment 11 of this bugzilla report.

Just installed POE myself after not playing for a while. Wanted to play in the
the newer 2.x version a bit.

I get the stuttering on default settings as well. Something that helps is to
turn off the GLSL. However, if you press F1 in game you can see the frame
time/latency/fps graphs. Look at the fps graph and frame time graph if you are
having this issue. You will notice spiking occuring a lot in the fps graph
where it seems like the card cuts out performance for some reason and drops
down to like 10fps, then resumes as normal. if your GLSL is enabled all sorts
of crazy lag can occur. I have noticed this in town especially.

I turned off my GLSL and it helped mitigated the effects of all this stuttering
substantially.

I've experienced similar issues while playing Path of Exile and the combination
of disabling GLSL and using the following commandline switches for Path of
Exile:

-ns
-gc 1

completely removed any and all stuttering.

-ns will completely disable sound and with it, its sound engine and with that,
its need to load sound assets.
-gc 1 will make its internal garbage collector more aggressive, putting less
memory pressure on the machine it is played on.

I also did experiment with nopreload, waitforpreload and combinations of either
of those in conjunction with ns, gc 1 but I found the preload commandline
options to be of no constructive use.

This seems to be the way to go
But i have no idea how to use these commandlines or where to insert them. Could
you explain real quick how you did that? I am using the Non-Steam version of
the game.

You append them to the command you use to launch the game.
So, if you run the game from a terminal, you just tack it on the end, like so:
wine PathOfExile.exe -gc 1 -ns
If you run it using a shortcut, you'd need to edit that shortcut and append it
there.

I'd like to note that -ns seems unnecessary at this point.

The severity of this bug is somewhat overstated, at least in my experience.
Running on:
Intel i3 4170 @ 3.7GHz
8GB Ram
NVIDIA GeForce GTX 750Ti

and with -gc 100, the "constantly" from the bug report is surely wrong.
It will stutter occasionally, drop from 60 fps to 25-30 (Vsync on), and very
occasionally drop all the way to sub 1 fps.
This stuttering is more prevalent in groups, in higher level content, and in
areas with patches of burning/shocking/chilling ground. Basically, the more
effects are happening, the more work has to be done, and the less fps you get.

-gc 100 seems to keep these assets around in memory, though, so the stuttering
is much less noticeable, at the cost of eventually crashing the game due to
running into the 32bit memory limit.

i cant figure out where to put these gc 1 and ns.
i am running PoE from my playonlinux. when i run the game via a shortcut
'/usr/share/playonlinux/playonlinux --run "PathOfExile" %F' i cant fit them in
anywhere without getting errors. same goes if i run this in a shell

Well.
What you're trying to add to the execution of the program is called an
Argument. Normally you append them after the instruction to execute said
program, in order to give additional instructions on how the program should run
and behave.
The easiest way to see them in action is to open up a terminal and comparing
the following commands invoking the ls program (no quotation marks):
"ls"
"ls -l"
"ls --help"

With playonlinux, you have to Configure your shortcuts to add arguments to
them.
http://wiki.playonlinux.com/index.php/The_Configuration_Window#The_Main_Conf...
Have a look at the second image on this page, the one with all the red boxes
and numbers.
You'll want to add the arguments in the "Arguments" box, here number 16.
So, in there write "-gc 100", again no quotation marks.
I still don't think -ns is necessary, but experiment away.

I can confirm this in Wine 2.9 with both Intel and NVIDIA graphics drivers. The
game client has changed a lot since the bug was opened but the problem
described in comment 0 is still present.

Wine 2.9, MacOS: same freeze/stuttering issue. It is much much better on
Nvidia+GLSL disabled, but in that case some effects aren't rendered.

I put some crude timing/debugging into glsl_shader.c: I'm pretty sure this
issue is shader generation related.

One particular attack effect always stutters for me on first load; triggering
it causes  the generation of about 10-15 shaders, most of which take around 8ms
to load, with one or two taking around 12-15ms. I'm not sure if they're all
generated on a single frame, but it's probably enough to tank the frame rate no
matter what.

The game is frequently loading new shaders. You can mitigate it a bit by
forcing some preloading via the command line options, but it still doesn't
preload all monster shaders. Those seem to be deferred until they're actually
needed.

I suspect this is likely going to be an issue until either 1) the PoE devs
change how shaders are loaded in the game or 2) the wine generation of
hlsl->glsl gets significantly faster.

Out of curiousity, did your timing reveal if the main delay was due to
HLSL->GLSL translation or due to OpenGL Compile/Link time? The former we can
probably cache to disk (at least, it would be a potential solution); the latter
we can do nothing about unless glProgramBinary is available (it isn't on my
laptop).

It was mostly in OpenGL compile/link if I'm remembering correctly.

With NVIDIA and glsl=disabled, as said the resource loads are not an issue. The
eventual massive slowdowns during lots of spell effects are (at least with the
spell effects created by my character's build) caused by massive heap
fragmentation in RtlAllocateHeap. Adding HEAP_freeListSizes entries of 0x198,
0x8c8 and 0xbc8 nearly entirely fixes this for me, though after a few hours it
started lagging again and then crashed shortly afterwards, so it's still
leaking somewhere (which might be a partial cause of the fragmentation).

Previously I was getting crash-on-startup from glsl=disabled. I patched wined3d
to increase the number of float constants (my gfx driver reported only
supporting 128 constants, but some PoE shaders use up to 140):

             ps_consts = gl_info->limits.arb_ps_float_constants;
         else
-            ps_consts = min(gl_info->limits.arb_ps_float_constants,

gl_info->limits.arb_ps_native_constants);

if (gl_info->supported[NV_FRAGMENT_PROGRAM2])
         {

After this change, glsl=disabled works. I also had to add the game options
"--noasync --nopreload" to prevent an outbreak of black/missing textures.

A few effects are missing due presumably to my horrible patch and the limited
HLSL shader support, but it works well enough to be usable. It still crashes
after a while due to memory exhaustion; this is tracked in bug #43545.

Disabling GLSL in WINE fixed the stutter for me completely. I have played my
newest character for 17 hours with no stutter.

I am on Wine-staging 2.17.

For Users Running with an AMD GPU this setup worked for me

Build
Core i5 kaby lake
RX480
Wine 2.21, using winetricks and playonlinux
Set on Windows 8
use winetricks and get vcrun2015 riched20 usp10 corefonts
do not disable glsl it will crash immediately

at this point the game should run but have massive screen flickering issues.
the only thing that solved this for me was to disable engine multithreading in
the in game settings. it doesnt completely remove the stuttering, but it makes
the game playable without the need to discover if you're epileptic or not

I also have the arguements
-gc 1 -ns
set up but I'm usure as to how well they're helping
