Anecdata: I play a silly amount of World of Tanks on PC (DX11), running the x86 Windows release through parallels on the Mac is significantly more performant than it is to run it on MacOS via the official codeweavers wine wrapper.

This is likely due to only one layer of translation being done in MacOS, as opposed to the two of Wine.

I really hope this leads to performance enhancements with windows clients on parallels
