DXVK for Vulkan-based D3D11 in Wine version 0.61 is out with improved performance

Quoting: MacGyver69I'm so happy I can play Witcher 3 again in Linux with DXVK. One major issue for me is Witcher 3 still crashes when I try to play 3440x1440 resolution fullscreen. Hopefully that will change in the future.

Did you report the crash to the bug tracker?

TW3 is almost playable, except for stream output which causes distorted monsters. Unfortunately that last bit might take a long time to implement.

Quoting: ShmerlFrom DRM-free games, I've heard Elex works well.

Unfortunately it seems that wine 3.10 broke it, at least I had no luck running it since then. I'd appreciate if someone else who owns the game could test that.

There was a rumor that Valve hired the DKVX developer and considering all the other things (MoltenVK, active participation in Vulkan spec and drivers development, Linux support etc.) I can speculate that a year from now or maybe even earlier, given that DXVK seems to be very focused on GTA5 and TW3, they're going to introduce partly-supported Steam Windows games on Linux and probably Mac via DXVK => MoltenVK. I think it's quite the reason behind the acquisition and open-sourcing MoltenVK, to make it work with the already very good DXVK. Just like they do for the keyboard+mouse games in Big Picture (it's unsupported but you can try if you dare). Steam might create a separate wine prefix for each game, automatically install missing libraries and do overrides if required and in the end provide an experience similar to PlayOnLinux or Lutris. Or even incorporate those projects to some extent.

The bridges are built from both sides. The porters and devs are porting to Linux, Valve is doing their part for those who didn't agree to for some reason. We, the customers, benefit from all those efforts as well as Valve and the devs.

Yesterday I tested ELEX with wine 3.11 + DXVK from git + Radeon drivers from Padoka PPA and all worked fine, however I had 53 FPS on Ubuntu vs 75 FPS on Windows with the same settings. Performance lost in The Witcher 3 is smaller.

Weird, it crashes for me right after the Piranha Bytes logo with *any* version of wine that is not the Arch build of 3.9 (non-staging). Even my own 3.9 builds crash the game for some reason.

Performance cannot really be improved any further and 70% of Windows perf is to be expected.

MoltenVK doesn't support tesselation shaders so far. That's a major requirement for TW3, so DXVK → MoltenVK → Metal isn't going to work for it well until it's implemented:

Did you test with wine 3.11? I think that 70% of performance compared to Windows may be related to CPU utilisation issues in Wine, because when I run the game with taskset and choose 6 instead of 12 available threads performance drop to even 40 FPS, so it's something wrong, because on Windows this game use just 2 threads most of the time. When I assigned just 2 threads to this game via taskset I just had 12 FPS. I think that in optimal scenerio 80% of the performance is realistic (eg. I have around 80% of windows performance in The Witcher 3 on Linux).

BTW. I have Ryzen 1600X + 3200MHz RAM + Radeon 580 8GB.

I got Elex with a major discount recently, so I'll give it a try with dxvk soon.

Has anybody with an Nvidia card done a Linux - Windows performance comparison with this release? It says some nVudia cards should see a performance boost - wonder how much.

Game is running perfectly fine on my system.

I'm running Manjaro Linux, with dxvk-bin 0.60 (from AUR) and wine-staging-nine-3.10 (from Archlinux repo).

Are you sure to have dxvk correctly setup? Try the usual:

env WINEPREFIX=/mnt/storage4/PlayOnLinux/wineprefix/elex setup_dxvk64 reset

Followed by

env WINEPREFIX=/mnt/storage4/PlayOnLinux/wineprefix/elex setup_dxvk64

I'm running GoG version of the game, with an absolutely vanilla wine installation (no additional libraries, if I recall correctly).
