This mainly happens on faster cards, capable of rendering a lot of FPS, much more than what the game is demanding. We've tried using an external FPS cap program, but it caps it at 30 FPS and turns the game very sluggish and with random crashes so we had to disable it.
Overclocked GTX260 here, no sluttering at all. Almost always 60FPS in-game, 30FPS cap in menus (coz it's on flash with 30fps cap, obviously).
Also, have you tried FPSlimiter (info)? Works for DX9/XP only, tho.
Tried it thanks. didnt work.
My frames are always @ 60, they dont budge (with v-sync ofc, wich is the ideal) so its not realy a FPS issue, the problem is that @ 60 FPS, synced with our LCDs at same frequency, the Tearing is way over the top. If i disable V-sync its the same, so it seems that v-sync is not realy cutting the tearing, just limiting the FPS @ 60, wich is not normal for a game using v-sync) Large horizontal stripes apear on the screen, like if i had the V-sync disabled and 300 FPS (the behavior is similar)
PLaying this game with v-sync and playing another game with no v-sync @ 300 FPS is the same, tearing-wise, realy bad.
I guess there is some kind of incompatability between the engine code and V-sync that just limits the frames @ 60, but the image is rendered inconsistantly to the screen.
