Winlator dx9 regression at 2.5.x builds
Duplicate of #4484
It appears to be an issue with Winlator/the Termux X11 stack. We don't support that as a target platform and regular systems are fine as far as I know (Nvidia, AMD, Qualcomm Linux).
I cannot reproduce the issue, I use a Google Pixel as a phone which has an ARM Mali GPU.
Maybe you can bisect it down to the individual commit that regressed performance.

welp I tried.. I use git graph to visualize it when d3d9 starts to dip on winlator. because its easy i just right click and checkout

failed means its under 400 fps
passed means its over 1.5k+ fps xD
i dont know i guess i will just skip 2.5.1 for now..
it all start on [dxvk] Use timeline semaphores for GPU synchronization commit.
Yeah someone worked out that this is almost certainly caused by turnip having to emulate timeline semaphores when running on top of the proprietary Qualcomm kernel driver. It's not really viable for us to revert back to the old path, so future versions of DXVK will remain slow on this platform.

what about an environment variable or an option in config file to disable that timeline semaphores?

Too much maintenance overhead to keep both paths around.
Nothing extracted yet.
System information
