Latest GOG release (1.31 or GOTY)
The game now works with Wine staging which includes key patches for it. You still need to enable CSMT and OpenGL version in registry (see howtos).
After that it produces very good result, but since there are still some graphics artifacts left in certain areas, I give it bronze.
CPU: Intel Core i7 4770.
GPU: AMD RX480 Sapphire Nitro+ (4GB VRAM)
OpenGL renderer string: AMD Radeon RX 480 Graphics (AMD POLARIS10 / DRM 3.10.0 / 4.11.0-1-amd64, LLVM 4.0.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.0-devel (git-f7f2fa8eb1)
I get around 40-50 fps, when threaded dispatch is enabled.
What does not
There are some glitches here and there (see known bugs section).
What was not tested
Didn't finish the game yet and didn't play any expansions.

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.
