I7 3770K@4.5ghz 6950 crossfire 8 gig windows 7 64 Hi all. I have been having this very strange problem with vsync for sometime now and only recently discovered that it was something to do with v sync itself (I think). This is what I recorded Basically in some games (not all) I get what is shown in the video. Now the thing is I found while I was playing around is that if I disable v sync totally, this stuttering/tearing seems to go away by quite a lot. The fps goes to 90 (I think cod is fixed to that) and it smooths out a lot but its still a little jittery and not perfectly smooth. This is also the case with bad company 2. I never had a problem with any game up until about 2 years ago when this started happening unexplainably. Another strange thing about this is that it only seems to occour ONLINE. Single player has non of this at 60fps. If I use a 360 controller to move there is no stutter/tearing I had the same issue with battlefield 3 but for some reason I cured it by limiting the fps to 59.95 and its smooth as butter. I have tried this with some of the other games but it does not work. To add to the strangeness this also happends on a completely different PC I built a while back. And led me to believe it was an internet problem. I ran many tests all to come back clear, I even changed providers. again as I say it only happends on some games not all. games affected: BF Bad company 2 All Call of Dutys Crysis 2 and a few more. games not affected: counter srike global offensive rising storm/red orchestra war thunder bf3 (with fps cap) Things I have tried: lots and lots of different drivers Disabled crossfire upgraded mobo, cpu and ram tried 3 different monitors tried taking my pc round a friends house (still happend) switching from hdmi to vga to dvi reformated windows and the list goes on. If anyone has any ideas about this, please let me know!
