One thing I’ve learned with sim racing is that USB is absolutely horrible in a lot of cases where there are many devices attached. Try messing about with the ports and see how it affects the devices giving you grief.
I tested out the smoothing tonight briefly in .144 and can say that in Raceroom at least it felt pretty smooth, I think improved over the previous builds. However, I realised that Raceroom also gives low GPU usage, same as rFactor 2 and ACC. So, I think what I meant when I said I don’t get the issues in other titles, on rFactor 2, was that I don’t get the issue in Assetto Corsa. It’s my most driven sim and I sort of forget how the other ones react. Really looking forward to a fix. As usual the trick worked BUT with Raceroom as soon as you go back to the game it goes back down to 70%. You don’t even need a menu to trigger it back to normal, just going from virtual desktop back to the game triggers it.
There must be different levels that each game works at.
