Hello,
I used to have some additional parameters in start script to set server process affinity but seems that it doesn't work anymore. 
Is there any way to set X affinity to server process?

Kind regards,
Adriok

Hello it’s just our experience.  i dont remember where i read it but it seems work for us. we use /AFFINITY F for processor 0 - 3 and /AFFINITY F0 for processor 4 - 7 for our 2 Servers on one dedicated Server.
But im not sure, but it seems Rust Server use just 1 processor it’s just good if you run 2 Servers and you will restart one of them so they don’t conflict togehter, and the Running server fps dont drop. 

if I am wrong please correct me. :)

But you should add "start /AFFINITY F" in start script. I used to have "start /WAIT /HIGH /AFFINITY 80" but doesn´t work properly.

yes similar like you start /WAIT /HIGH /AFFINITY F0 RustDedicated.exe . . . .

Yes but It doesn't seem to work fine
