It's merged to master now.

Should I call this a small improvement with Wine Staging 2.20? The "black veil" in the starting room of Kaer Morhen now has a texture. FPS is still a bit wonky but stutters more compared to 2.19.

It has been a texture for a while for me. The root cause of this bug is still present.

I have a feeling that unless Nvidia will fix their kernel module, this will remain an issue. May be Wine developers will find some workaround, but they are more focused on features than on optimizing for Nvidia blob now.

From Henri Verbeet, one of the Wine developers:

QuoteAs a rough estimate I'd say about 40-50% of our users are using NVIDIA GPUs, of which about 80-90% are using the proprietary drivers. That's certainly a significant number of people, which of course we'll try to help where reasonably possible. But it's not just about numbers; Wine is in the first place a Free Software project, and quite frankly plenty of us would be happier if more of our users used Free Software drivers.

Interestingly, it means that number of Mesa users is higher for Wine, than percentage in POL stats (27% open / 73% blob).

Maybe it's because of how TW3 works with Mesa drivers? And also I think there's no script for TW3 in PoL to install it easily and make it work properly, so Wine is better choice.

In part, but Wine in general tends to work better with Mesa.

POL is using Wine, but until recently, stock and staging Wine weren't ready enough and manual tweaks were needed to make a working combination. Now staging will probably get in good shape.

I think in part, the best thing about Mesa and Wine is the Gallium-Nine feature. In many gameplay benchmarks I've seen it's almost or on par with Windows. Meanwhile Witcher 3 is a perfect example that even without Nine, Mesa still beats Nvidia.

Today I've finished dusting off (literally in that sense) my old i5 system, highly thinking about putting an average AMD gpu dedicated just for Wine gaming and a few benchmarks. Will wait to see what else AMD has for show before diving in though.

I've never had an AMD card until now so I'm considering what it'd be like to use it with MESA.

These days it's a good time to get AMD already.

Quoting: GuestThis is not good example, Nvidia drivers or Wine have some major problems with performance,
GPU utilisation don't go more then like ~60%. Going for uber to low on Nvidia give max + 20 fps (1440p uber -> 720p low) bug #42592. But anyway AMD is still better choice for Linux.

Looks like your CPU is pretty much fully loaded (always hard to judge with hyperthreading). Apparently, this doesn't happen with Mesa. Which means that the Nvidia blob is apparently wasting a lot of CPU when processing the Wine rendering. This probably means that Wine is doing some pretty uncommon things that the Nvidia blob was not optimised for (or worse even sacrificed in favour of other optimisations).
