Hey I downloaded the game on steam yesterday on steam and my first lap I got this terrible stuttering whilst cornering. it seems to keep flicking back to a certain frame in the middle of the corner then finally lets go once out of the corner making it unplayable. Have tried every graphics setting possible. System specs: cpu: 4930k (stock clocks for this) mobo: Asus rIV black GPU: 3x gtx titan black at 1250mhz (run at 960 for this game) mem: 16gb corsair dominator platinum 2133 win 8.1 I havnt seen anyone with my exact problem, I tried disabling sli and ran it off one card and still the same exact problem. I recorded one lap of melbourne to show exactly what is happening. http://www.youtube.com/watch?v=ySqtui8LD7c&feature=youtu.be I am using a ps3 controller with motioninjoy, could that be an issue? Any help is much appreciated.
