No it isn’t, I didn’t claim it was, and Valve is doing a good bit more than mere pre-configuration.
Valve is contributing efforts to improve Wine, DXVK, VK3D, shader-cache management, and making their use simple and easy.
If I figure out how to use Bottles, then in a literary sense it is completely correct to say: I figured out how to run windows software on Linux.
The sentence doesn’t suddenly become false if I didn’t write every line of code, from kernel to compatibility layer, that my PC is executing to do it.
DXVK is sooo good now I install it for half my games on my Windows machine just for the performance gains
I’ve been doing the same thing, if the performance of a game feels like it could be better I slap that shit in there and it often drops GPU usage by at least half, it’s frankly ridiculous.
