           Summary: Massive FPS drops since Version 6.9 up to 6.14 in BF
                    1, BF 4 and BF V
           Product: Wine-staging
           Version: 6.14

Hello,

using wine-staging 6.2 as reference. Since wine-staging version 6.9 i can start
BF 1, BF 4 and BF V again. But i notice a big FPS drop while playing online. I
tested all versions from version 6.9 to 6.14 (except 6.13, can login in origin
client at all) and all versions have the same drops when playing online.

In the Menu screens or Lobby there is no problem at all. Also the fps drops
seems not so big while playing in single player modes.

All versions tested with same OS Version kernel versions and hardware settings
in 2K.

Using wine-staging version 6.2 frame rates are in BF 1 between 100 and 144 fps.
Using any newer version of staging the fps drops to the range between 24 and 40
fps. In online mode this is unplayable.

Reinstalling version 6.2 of wine-staging solve the fps drops. I can't test with
normal wine because i can't start the origin client at all. Crash to desk. Not
tested normal wine version 6.14 but i think it does not let me start the origin
client like the other versions.

Maybe it was not really a graphic problem here. For me it has to do with
massive online play. Receiving and transmitting network messages my be here the
root of the problem. Have to look to changes in network changes starting from
version 6.3. Maybe anyone has more information regarding this assumption.

Thank for your help.

All the Best...

Does this bug occur in upstream (non-staging) wine?

Hello,

i'm sorry. I can't test the upstream wine version to check if the fps drop is
not a staging specific problem. As i mentioned, i can't start the orign client
with upstream wine versions. I crash to desk before i can login the client. So
i unable to try any BF Title.

I can't say it was a staging or a upstream wine problem. I hope someone knows
about changes in regarding the slow performance in fps. Further i not really
sure it has to do with the network implementation.  So i have to test with
newer versions and try wireshark to take a deeper look at the communication
level.

When i use the newer version of wine-staging i noticed some more graphic
details regarding Particle Effects in Game. But at the moment i don't really
know if this has to do with massive fps drops?

Is there anyone who play BF 1, BF 4 or BF V with wine upstream or wine-staging
and has the same problems or noticed a drop in fps count while playing online?

btw.: I using DXVK 1.9.1 for DX11 support in wine-staging.

Thanks for all your help, support and investigation.

All the Best...

Hi,

I continued to test the problems of massive fps drops with Wine / Wein staging.
I tested up to version 6.16. As I mentioned earlier, there are no problems with
version 6.2. With version 6.3 through version 6.8, I couldn't log into Origin,
so I can't exactly identify if one of this versions are part of the problems.
> From version 6.9 of wine-staging I was able to log in again and play BF 1, BF 4

and BF V. But with this version I notice a massive drop in FPS when I play in
large online battles (up to 64 players).

As I mentioned earlier, I find that the fps drops are not really a problem as
long as I play single player mode. But as soon as I play online, the FPS
counter slows down in a region where online gaming is impossible. It appears
that network communication is the root of the problem.

I continued testing with Linux tools and Wireshark with the newer Wine staging
version up to 6.16. To me, communication at the lower network level seems to be
normal. Maybe some more close waiting sockets.
> From this point I am looking at code changes from dlls/ws2_32 and Server/Sock.

But there have been so many changes from version 6.5 to 6.16 that I am giving
up rebase all changes. In addition to all logical changes to the code base,
ws2_32 was converted to the PE format.

At this point, it makes no sense to me to bisect the code or rebase it. Knowing
this, I think it's clear that this appears to be a vanilla wine problem.

Maybe I was wrong and all the network code is working fine and the problems
with the fps drops have a different background. But I tested a BF V Combined
Mission against bots alone and had 120 fps in this mode. Complete the mission
and join a massive MP mode (Conquest with 62 players) and the fps will drop to
32 fps. The only difference between these modes is the enormous number of UDP
socket communications used to synchronize the game objects. So it looks like
the root of the problem is network communications.

Does anyone play BF or another MMP shooter and have no problems with the
current Wine version 6.16. I use Opensuse Tumbleweed with 470.56.05 of NVIDIA
Display driver and DXVK 1.9.1. Maybe other distributions don't have this
problems?

Thanks in advance...

All the Best...

Hello,

after such a long time without anyone having any other problems with frame
drops in MMO games like me in the current Wine staging, I thought the problems
had something to do with my system setup or a faulty part of my system
configuration. I have tested all versions up to 6.19 and all show the same
problem, the frame rates drops massive when playing online. As mentioned in my
previous post, I tested the raw network traffic without seeing any real
problems with UDP traffic.

And now, with version 6.20 ... what ... the frame rates are almost in the range
of version 6.2. Sounds like a joke ... version 6.2 and now version 6.20 but
it's true. When joining a game in BF 1 or BF 5, the frames are almost at the
level of the old max fps. Maybe 5 or 10 fps less :-)

Since it doesn't seem to have anything to do with the lower level UDP traffic,
am I suspecting a problem with HTTP or Secure Socket Communications? I don't
know, but the performance is much better and almost as good as version 6.2.

I think this seems to be fixed and can be closed for now.

Congratulations to everyone who makes this possible and to all the great people
of the wine/-staging and wine ecosystem!

All the Best :-)
