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.
