Oh nice with some fast replys

First of all I just assumed that many has this problem since theres loads of post about it.

Other players are moving normaly, no skipping or anything.

I have tried setting affinity and also the HID solution and turning off shadows and weather, but no luck.

Running through the "unmentionable" program makes everything a lot better but that half second stutter still persists.

If I stand still it all looks normal, but as soon as I start turning the camera it shows.
It runs smoothly then makes a jitter, then smooth and then a stutter, not like micro stutter more like 5 micro stutters combined every one to two seconds.
