Thanks for the reply Ralph. I seem to have MPC-HC working now although it doesn’t always work first time, sometimes I have to close the program and re-open it for it to pick up the OR. I’ve also noticed this happens with Elite Dangerous so its probably not related to vorpX.
I was using the Game optimizer in the config app yes. Out of interest is there any difference between the “Apply Selected” button (next to the “Restore Backup” button) in the game optimiser and the Apply and Apply & Close buttons below?
