So Darksiders 2 was updated today to DX12 and has implemented an RT mode... and you guessed it.. it now stutters when compiling shaders. There's no shader precomp process.
Devs actively updating these old ass games to the new APIs and basically making them perform worse. Sigh
Right now the patch is only available as a beta channel, so it's still possible to play the older version of the game, and perhaps it isn't quite 100% ready to go and they're basically testing it out?
I don't think the new version supports the old renderer at all, it requires DX12.
