I worked around the vegetation bug, by increasing heap sizes, but it also worsened performance. See here.

managed to get vulkan/dxvk running :) compiled wine-vulkan, installed like i tried 100 times before and at some point it works ... not sure what vodoo i did. anyway, i just teste dxvk .40 - vega56, ryzen 1700@3700, kernel 4.15.9, oibaf mesa, ultra setting with medium shadows on 2560x1080 - outside big towns i get stable 56 - 60 (fpslimit at 60) and inside novigrad i get 52-55 at market square. old wine 2.21 was 22-25 with medium settings. Thank you for dxvk:). rotfiends/alghuls looks at this moment a little strange/trinagled :)

I played a little more in Blood & Wine. If i am in a part of the world where y can look very, very far (top of a hill or so) the fps go down to around 45. but its still a super fps and i never thought that i can play TW3 on ultra so fluid. there was one place in B&W where rotfiends/Moderhäute look normal.

dxvk still needs stream output, so until then some monsters will be distorted. @maspeber: can you please test this save, and check if you get shadows problem there? See in that issue for details. Please comment in the bug.

shmerl, i downloaded your save, unpacked, put it in my save game dir and dont see your save. It from 25.03. 14:43 but it doesent show up. I had this issue a while ago. I am on GOG/GOTY 1.31 - do you know why i dont see the save?

No idea, I'm also using GOG/GOTY 1.31. Try to temporarily move out all your saves, and just leave my save there.

By the way, make sure to use classic installers for the game (no Galaxy). May be Galaxy interferes with saves.

Yes I always use the installers without Galaxy. But I cant use your save. I dont know why (may different language or patch or whatever).

Can you post a big of the scene to test and a pic of the map where I can find it? Than I post a pic in reply.

Thanks

The issue might he hard to reproduce, since it can depend on weather conditions. I'll record a small video of the problem.

@maspeber: see here.

Is there a definitive way to make Witcher3 work with dxvk or what is the most safe bet?
I've been trying now with wine-staging 3.3 and 3.4 on a prefix with dxvk enabled (works fine with likes of Battlerite, osd, etc), alas Witcher always just gives me a blank black screen and gets stuck. :\
