Hello, im experiancing lagspikes wich are really effecting driving. I dont know since when i got this problem but its getting really annoying now. Im running rfactor on 200 to 500 frames per second so thats not the problem. But one thing i found out is really wierd to me. I got 8 cores, rfactor only uses 4 cores 1/3/5/7. Now the 1st one is maxing out all the time when driving. The other three are working a littlebit. Maby that has something to do with the problem. The lagspikes are short but while they are happening i cant shift. And when steering into the corner the car wont do anything until the lagspike is gone. So i miss the inside of the corner a lot of times because of that. If anyone knows how to fix this, post a commend here. Ore contact me via mail ore msn if you have me.
