Thanks for the reply! So I actually tried an older virsion I have on my computer and it seams to work better then the newest release. Less fps but also less Jittery. So I was thinking if you have any 4.0 releases that are not beta. maybe an erlier 4.0. if I can try one of those maybe that will work well with both good fps and less jitter. If Not i dont mind using the virsion 3 release witch seams to work.
