NOTAM if you have NEVER used Programs like Project lasso, CPUCores, Windows Affinity, or any program that has the ability to lock a process to a single core or thread
This is most likely not your issue
things to try if you're having slow performance.
Make sure you have DCS set with normal processor affinity,
Programs like Project lasso, CPUCores any program that has the ability to lock a process to a single core or thread will break DCS if you have used it to control the DCS process.
Windows has this ability as well, Unsure if there is a way to permanently set affinity in windows. Maybe a registry thing.
We were using Project lasso to lock DCS to our best cores to get the best experience now with Multithreading it is unnecessary
FIX Disable Project lasso Or other programs that can set CPU affinity, Reboot, and see what happens.
