Ok , managed to find the fix

Yup :-P
Was middle of the night and could not sleep and decided to listen to Witcher soundtrack on youtube which made me nostalgic to play it

Yeah, the Witcher soundtrack is amazing:

I've been experimenting a bit with TW1 again, to see how Wine is handling it now. There are still these black textures flickering indoors, which can be worked around with d3d9_35 native override (installable with winetricks).

I also tested wine-nine-standalone (relevant only if you are using Mesa): https://github.com/iXit/wine-nine-standalone

The idea is same as dxvk, you just get their dll and symlink it to d3d9.dll inside your prefix. Make sure you also have Gallium 9 packages installed. In Debian it's libd3dadapter9-mesa:i386.

It has nice performance, however the flickering is still there unfortunately (unless you rely on d3d9_35 and I'm not sure what that combination is using in the end). Or may be I'm doing something wrong?



Also, there is no explicit vsync option in the game, so with Mesa unless you are testing max framerate, you can set:

export vblank_mode=3

d9vk started rendering TW nicely!

But now I need to figure out how to limit the framerate, since there is no built in vsync option in the game. Does radv have some environment variable that forces vsync?

Oh, there is a way! This forces vsync:

MESA_VK_WSI_PRESENT_MODE=fifo

Hm, forcing vsync for 60Hz monitor causes periodic black blinking in the game. I wonder if it's d9vk or radv issue.

What about libstrangl?

https://github.com/milaq/libstrangle

I didn't try that, but regular vsync forcing shouldn't be broken really. It's a bug somewhere.

No more blinking with latest d9vk! The game runs perfectly.

Also decided to play Witcher 1 (GOG with Lutris) after trying a little bit of 3 and realizing I have no clue what's going on plot wise.

It's fun, but I've run into the weirdest bug, I think. In the tutorial, after Leo dies, clicking on the meditate button when talking to Vessimer does nothing. Pretty much stopd all progression right there.

If tried looking at the wine appdb with no luck and googling. I've seen others post something similar, but no solutions.

I've tried re installing, restarting, mods, no mods. Each time the same thing happens... Clicking on meditation does nothing. So weird.

I'm sad because it's really fun, or already the tutorial is, lol. Any suggestions?

Hm, I don't remember that particular bug. What if you reload some earlier save and try to replay that part?

Same thing. I've tried reloading manual and autosaves and complete restarts. I've gotten it down to when I can do the while tutorial mission in less than 20 min, lol. Only think I've not done is fight the frightener ( I always choose to go to the lab). I'll try that in a little bit when I get a break.

Edit: I did the frightener branch. Still same bug. Clicking on the meditate dialog option when talking to Vessimer does not start meditation

Holy mother of pearl, I finally figured it out.

Switched to my system default wine (6.13) instead of the Lutris version (6.14fshack).

Got the option to meditate! Sweet!

That was a weird one!
