I've found this from Phoronix website. Looks promising.

Post Update -

I gave this patch a spin earlier yesterday morning, Downloaded Base Wine 2.21 > Applied Staging 2.21 patches > Applied Andrew's patch. Didn't have much luck. Games ran, sound audible but with a black screen.

I recompiled it again using latest patches, black screens are gone and there are some serious improvements this time (also a regression):



As you can see above, Witcher 3 improved a lot for Nvidia, however all the characters (including Geralt's horse) are invisible. Also noticed an important factor - my GPU usage peaked to about 80%.

Will keep posting with updates :)


For the moment I can't seem to manage to build a WoW64 Wine build (32+64bit combo) so all my tests will either be a Pure 32bit or 64bit build.

I wonder if there is any work duplication going on, since Wine developers are now also working on fixing buffer pool performance.

This also needs to be tested on AMD gpus. My experience on AMD gpus with these patches was atrocious sadly. My wow framerate droped from 60+ to about 10-20 in sunstrider isle newbie area with dx9 and dx11

Hey. I also gave these patches a run, but with League Of Legends.

Quick summary here:

staging-2.20 avg: 83.83
staging-2.21 avg: 83.65
staging-2.21+pba patches avg: 104.77

Have you asked the wine developers and the pba guy this? It might make more sense on #winehackers or wine-devel than here to wonder about it.

Tested on TW3 w R1700 och GTX1080:

 ~7 fps wine master latest
~20 fps wine master latest with (new) buffer patch
~20 fps wine staging 2.21
~13 fps wine staging 2.21 with PBA patches

PBA patches gives invisible Geralt etc as already reported (using 4 from: ae1cb0d Fix constant buffer invalidation).
Not sure why the Nvidia performance improved so much for Avehicle7887 but not for me. :-/

Rebuilt wine-pba with latest patches and ran League Of Legends again, same test full bot game.
It was a bit shorter game tho but i did see around 100-130 fps most of the time.

staging-2.20 avg: 83.83
staging-2.21 avg: 83.65

I have re-tested Witcher 3 under different CPU cores active, using just the first 4 cores produced almost same performance as running on all 16 threads. GPU load peaked 83% usage in about 10 mins of gameplay. I'm in the process of building the 32bit Wine version atm, so I can do more tests.
