That would be excellent news. Even my 980ti was cpu bottlenecked at 1440p (2700x)Saw a dev Q&A that mentioned they have significant CPU optimisations coming with the next patch.... significant improvements to multithreading and reduction in main thread bottlenecking. Might help with some of the performance woes for those already with beefier GPUs.
Broad target but billy big boss of the project (Jorg) says coming to Xbox in 2021... mentioned in this long Dev Q&A somewhere.
