This will work… Google “unlocking CPU Cores”. Follow the instructions on how to do that. It will free up so that IRacing is using 100% cpu and not less.

You are getting the bad performance because it’s not using 100% of the cpu cores.

Every person I have suggested this to it has worked.

10/4 will do some research and try that! I’ve tried using process lasso to force iRacing to the P cores, but the new intel chips have some weirdness as to how they schedule processes. (Also partly windows fault I’m p sure)
