Are you sure the game doesn't slow down on Windows or Gallium Nine.
The game is really inefficient.

Can you reupload your apitrace?

The apitrace is still available, you can download it still for next two weeks.
Also the game doesn't slowdown on Windows/Gallium Nine, the performance is better because in nosville (when you are around many people) you don't get instant framedrops to 30 fps, and on DXVK you do. Also, Gallium Nine have really better performance than DXVK, probably even better performance than Windows, what I saw from my testing.

I want also to note that I tested the game yesterday with mesa-git and the performance issue persists. Gonna answer next questions on VKx discord or here in next week, I'm pretty busy nowadays.

So, I'm here again. The issue remains even on Windows - and I supposed the problem exists in Mesa and AMDGPU/AMDVLK (AMDVLK has the same performance penalty, but thats normal, since it's not very different from AMDGPU). So conclusion is clear - something is wrong in DXVK.

D9 on Windows:

DXVK on Windows:

DGVoodoo on Windows:

Now i haven't compared to Gallium Nine (haven't gotten it working), but comparing 1.7.2 to 1.10.1 this seems like it has improved a lot. Unless someone complains maybe this one can be closed? Tho dunno if there are still improvements to be had.

With the fps cap it's hard to compare proper numbers, but the GPU load also kinda speaks for itself.

Native windows d9 is slighty worse it seems looking at cpu and gpu usage.
Tho dxvk frame times are a bit more up and down according to RTSS

Some more tests.
Unless my memory is just really shit or i missed it last time then it seems they've added a slider allowing to raise the framerate cap all the way up to 200 in a update.

Here are some tests with dxvk 1.10.1 and 1280 x 1024 windowed mode.

Linux tests are on proton 5.13 to get around the inputs not working wine bug. Also uses dxvk 1.10.1

The old framerate cap seems to be what caused all the extra frame timing variations as when it is raised to 200 as above you can see the graph is much nicer on windows. Even if the fps doesn't rise much from it.
Native dx9 and dxvk on windows seems to be at least on par and maybe dxvk goes ahead slightly also judging from gpu and cpu usage.

Linux seems to outperform windows with and without dxvk when i raise the framcap to 200 with around 15 - 20 more fps in this short test.
I also made a test where i set the framecap back to the 60 default and you can see the fps instead seems to stick in the low to mid 50's. Also frame timings are worse. So i would suggest raising the fps limit in the settings app.

Tho this test isn't a scientific controlled one as there are some differences in the amount of people i see now above in the screenshots even tho it is the same place. But performance seems pretty decent here in this area on linux with all these people.

@HoshiYamazaki Just to get a second opinion since this is your issue afterall, does the above ramble match how the game plays for you now with 1.10.1 & framcap at 200?

@Blisto91 Yes, I tried game on 1280x1024 windowed mode and I got similar performance to your, still using r5 3600/rx5700 XT/3200mhz clocked RAM's. But I would not agree that game performs better on Linux - the game performs slighty worse after logging into international first server, to first channel, while being in nosville. I tested both operating systems on FullHD resolution using Xorg. I got around 45-60 fps in Windows and around 40-55 in Linux, so not really big difference, I would estimate it as 5-10%.

I think this game just can't sometimes achieve 60 fps no matter what, I heard from some people years ago that they tried to launch game on NVidia Titan X and had similar results. But, even if Linux has worse performance, it's not really noticeable and, because of that, I'm closing issue by now. If somebody does not agree - please post feedback here.

Ah that sucks. My tests weren't totally scientific either hehe.
But at least it seems to not be as bad as it used to be and the game itself seems to be quite heavy. Hopefully the game or wine/dxvk can improve a bit more here and there in the future.

Sorry for mislead, I redone the tests and maybe because I'm little busy I didn't notice that game has better performance on Linux. On Windows - it has similar performance, it's around 40-50 fps, on Linux - 45-55 fps. I was switching the resolutions and I noted wrong fps scores... - I even use scaling for 4k display, so I must do bunch stuff around while testing. Anyway, as I said - the game engine is not able to achieve 60 fps sometimes no matter what, and if game runs better on Linux than on Windows, it's good reason to close this issue.

Again, sorry for posting wrong results - I really appreciate your work guys, and I hope you all will have good evening. Thanks for fixing nostale performance on Linux!

Quick note:
Redone the tests (third time), and fps meter was again different. I think it depends how you rotate/zoom camera and how many characters are around you. So, if anybody wants to compare results again, remember about that.
