I've just downloaded the demo for Rfactor2 and is on the fence about purchasing the full version. However, I can not seem to get the car to stay straight for it is forever jerking side to side. Yes....I am using an XBox 360 game controller for Windows 8. Is there something in the settings or driver's aide that can help stop this? I am in no way a sim guy. I just want to be able to log in some laps for fun and as I get better at it, I would ramp up the AI. Any help will be greatly appreciated.
