Can you capture an apitrace?

[onlylunix]

need instructions on how to do it

The trace only replays what looks to me like a part of the initial loading screen, did you actually go in-game to capture the problem while making the trace?

[onlylunix]

Yes, I played for a few seconds to make sure. The instructions ( https://github.com/Joshua-Ashton/d9vk/wiki/Making-a-Trace ) said to remove the dxvk, which I did. Of course, there is no bug without dxvk.

That's the only thing the apitrace shows. Please try make a new one.

Same problem with that one.

Same problem with that one.

ok, v3: https://disk.yandex.ru/d/25mqOo4ss8KEpQ

[K0bin]

Still same problem. Looks like this is an issue with the game. Unfortunately I can't fix this without a working apitrace.

I have an issue in this game too with DXVK 1.9.2, not with the clouds though, but with the skybox itself.

I can't record an apitrace, wine just crashes with stack overflow if i use the apitrace's d3d9.dll. However, i found out that the bad commit is https://github.com/doitsujin/dxvk/commit/78d22cc7a5e03817ed06002f50120bfe77efcdd3, reverting it fixes the issue. Maybe this commit also causes the issue @onlylunix has.

[K0bin]

@onlylunix Is your issue also fixed if you revert that commit?

If not, can you please bisect? (Find the exact commit that caused the problem)

[Kron4ek]

A build with reverted https://github.com/doitsujin/dxvk/commit/78d22cc7a5e03817ed06002f50120bfe77efcdd3

dxvk-1.9.2-test.tar.gz

[onlylunix]

A build with reverted 78d22cc

dxvk-1.9.2-test.tar.gz

yes, it solved the bug

Reverting https://github.com/doitsujin/dxvk/commit/78d22cc7a5e03817ed06002f50120bfe77efcdd3 helps with other DX9 games, too (RADV, mesa 21.2.2, kernel 5.14.7).

[DadSchoorse]

@zaps166 what games? And can you please create an apitrace of an affected game? The revert is not fully correct because it breaks wine tests, so it would be nice if I could look into what's happening.

Reverting 78d22cc helps with other DX9 games, too (RADV, mesa 21.2.2, kernel 5.14.7).

With this "revert" it has a better performance in BL2, I have noticed that with version 1.9.2 of DXVK, at certain times I suffer from "fps drops + stuttering", with this commit, it fixes that problem, is what I noticed.

It's more likely that it was just compiling shaders and those shaders were cached when you tried the build with the revert.
