Cannot change process affinity?

I can't seem to set a limit on the number of cores this game uses. I've tried doing a shortcut with the /affinity arg and using other programs to launch this game. Task Manager says Access Denied when trying to limit affinity. Please allow us to set the number of cores this game uses.

Can't stream or record very well and give free publicity (and/or visual feedback) if the game is hogging all the resources.

u can do that via launch options

You can set cores for steam.exe. Usually any child process you start via Steam will then use the same cores. Dunno if it works here, can't try it right now. EAC might interfere, but worth a try!
