Latest GOG release (1.31 or GOTY)
Fiddling with settings.
Playing for a couple hours.
What does not
Performance without dxvk is very poor.
Performance without dxvk is very poor, with many graphical glitches. So, first workaround: install dxvk via winetricks.
Running the game after installation requires cd-ing into the bin/x64 directory first (see below).
What was not tested
First, I installed dxvk via winetricks:
WINEARCH=win64 WINEPREFIX=~/wineprefix/witcher3 winetricks
Then the game:
WINEARCH=win64 WINEPREFIX=~/wineprefix/witcher3 wine /path/to/downloaded.exe
After clicking 'Launch' when the installer finished, I was able to play for some time.
Starting the game afterwards requires to cd into the bin/x64 directory first, like:
cd wineprefix/witcher3/drive_c/GOG\ Games/The\ Witcher\ 3\ Wild\ Hunt/bin/x64/; WINEARCH=win64 WINEPREFIX=~/wineprefix/witcher3 wine witcher3.exe

Currently with wined3d, The Witcher 3 is still affected by CPU-GPU buffer maps synchronization issue (bug #44315). It severely degrades performance.
Using dxvk instead of wined3d is the best course of action, since it performs very well, and also provides perfect rendering, as long as your Vulkan driver supports VK_EXT_transform_feedback extension.
