I'm having two problems with RRRE, I doubt they're related - one is a minor inconvenience, and the other makes the sim almost unplayable. The first issue is I get a message from Steam saying 'Failed to start game (app already running)'. The screen flickers, sometimes leaving me on the desktop, and I can select the RRRE icon on the taskbar (or Alt-Tab) and it will appear fullscreen again, usually in the middle of the intro videos. This doesn't seem to happen on the first launch of the game, only on subsequent launches. But even on the first time, it seems to do a weird flicker at the start, as if it's launching something twice. The second thing is a bigger problem - the sim will simply freeze for a few seconds in the middle of a lap. The audio continues, and the car is definitely continuing to move, as when it unfreezes itself a few second later, I appear in a different part of the track (usually in a wall). This can happen once a lap, twice lap, every few seconds, or not at all. It seems entirely random. I thought it was performance-related, but I'm getting a solid 60fps and it keeps doing it. When I've turned all visual settings to max, my framerate suffers a bit, but the freezing doesn't increase - I just played a few laps at max settings where it didn't freeze at all... so I guess something else is causing this... Any ideas/suggestions much appreciated.
