I’ve been doing multiple tests today in order to publish an update to
My 2070 SUPER 4K settings and suggestions - episode 2
During my tests, I’ve tried to see whether cutting in half the number of cores FS2020 is running with would allow freeing some of them for background Win10 tasks, so that if there is such background task popping in it wouldn’t affect FS2020 multi-tasking scheduler.
I’ve therefore launched FS2020 on the 9700K (8 cores, no HT), opened Task Manager, changed process affinity and only selected cores 1,3,5,7.
Results (non scientific whatsoever): when running only on 4 cores on this CPU there was no difference at all performance wise, no additional stutters either. Given the average load on all cores but 1, I even wonder if it wouldn’t run the same on 2 cores only.
Of course once they implement DX12 they will be able to take better advantage of multi-core for rendering.
