Latest GOG release (1.31 or GOTY)
Everything i tried.
But i just played a couple of minutes
What does not
In some cases there are black artifact that covers part of screen, but when you move it dissapears.
What was not tested
This was tried on game installed on windows through GOG Galaxy. Albait game runs ok, it's pretty slow. It doesn't matter if i switch all settings to low in game, the performance is almost the same. On i5 6600k and Nvidia GTX 1070 i get around 28 fps, on the same machine in windows 10 i get around 60 most of the time. Its on latest nvidia binary blob 384.59 No other adjustments except updating registry with stuff mentioned in comments/guide

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.
