Quoting: guitaristAny suggestion?

What are you running exactly? What is your distro, Wine and GPU / driver? I think your Wine simply has no built in Vulkan support like the error suggests. Some didn't catch up yet. Either install Wine with Vulkan enabled, or build it yourself with Vulkan support.

Quoting: sebishIn debian testing repository, wine (3.7) build with vulkan. It's work's fine with dxvk.

So its just an SID issue!

It doesn't make sense for Sid to have Vulkan disabled, and for testing to have it enabled.

But it's disabled in Sid indeed:

I recommend you to file a bug for wine-development package in Debian.

Actually, there is a bug about it already: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=896928

Quoting: GuestTW 3 runs really good on my system (ten years old AMD Phenom 8450 and a GTX 1050 2GB) via DXVK and Debian Testing

Besides missing stream output it runs almost perfectly now.

Quoting: GuestIt would be nice if there was some framework officially maintained by GitHub pages that allows easy plug and play of a donation page for open source projects. I would like to give a donation to Philip Rebohle.

He said in the past that he doesn't need such donations, which suggests that someone is already backing the project.

I assume that you mean this problem. How does it affect the gameplay?

Distortions of various models in the game. See:

My 1080ti is almost enough for 4k 60fps with high settings. Its like 80fps at 1440p then 45fps at 2180p, so close. Still playable at 45fps, it does have dips down to 37fps however.

If AMD flop on their next release then I'm sure the 1180 will handle 4k better. Under windows the 1080ti does fine at 4k and gets 60fps with high+ settings most the time but there are games like KCD that bring it to avg 50fps (on medium+).

Guess its too hard to optimize games for 60fps at 4k. Surprisingly fallout4 gives me 50-60fps, a game that is plagued with optimization issues!

@Shmerl: have you checked out wine-staging 3.9 yet? I'm curious if the performance is good enough to go back to Wine3d? The graphical artifacts caused by vulkan lacking stream output support are the only thing keeping the Witcher 3 from being a near-perfect experience on Linux.

I wondered the same thing when I read the news. Compiling Wine Staging 3.9 as I type this, it's late but will run tests tomorrow :-)

I haven't. The main work to support better buffers performance is done in some internal Wine branch (and it's quite non trivial), so it won't surface until they are ready.

I can give it a try though. May be they did publish some of it there.
