Latest GOG release (1.31 or GOTY)
This is the first time I'm giving the game bronze rating. It's actually playable to some degree now! Using Wine 2.3 with staging patches, and buffer pool hack (see below).
What does not
Graphics are still only working partially, but the game is way more playable than before.
What was not tested
Didn't progress far in the game.

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.
