I have got a little problem. The game works quite well. The FPS-rate is very well even if i use a little older system with just 2 GB Ram and a dual core which is quite old. even my nvidea card is not the newest one. sometimes i drive races without any breakdowns in fps but sometimes its just like a movie that pauses and then it goes on an then it pauses again. thats very stupid in corners. what can i do to avoid that?
