Hi, I'm having a recurring problem that I can't resolve. When I start a session, I can drive normally on the track but after a while, when I'm driving, my car decelerates on its own and it feels like a freeze but the AI cars are still driving at normal speed. So my car's speedometer reads 250 kph, for example, but I'm driving at 100 compared with the other cars, so it's very annoying when I'm driving. So I'd like to know if other people have encountered the same problem or not so that I can solve it. For the record, I've even tried lowering the graphics and not using AI, but it's still the same problem.
Could the pitlane speed limiter button(assuming you have a wheel) be triggering false imputs due to dirty or worn-out equipment? Try assigning the Pitlane command to a keyboard key.
It sounds to me, to CPU bottleneck. What are your pc specs? What cars and track are you using? How mant AIs are you using? What are the conditions of the session? (Day or night, rain, etc)
