Question about vsync and screen tearing?

buzzard · #1 08-21-2011, 05:54 PM

Wondering if anyone knows about screen tearing without vsync. I get smoking frame rates without, but get really annoying tearing/flickering around the prop. I can put vsync on (to correct the flicker) but am of course limited to the refresh on my monitor - 60fps. The propeller effect is better without vsync on, but i pretty much have to have it. Something of a quandary...

If there are any fixes so i can run CoD without vsync on, does anyone know?

I have:
AMD 965 BE 3.4
8 gB RAM
2 x 5830 in Crossfire
LCD Dell ST2410

First, only v-sync ON at one place - either in the card settings (CC) or in the game.
If u got v-sync in game on then try swithcing it off and turning it on in CC.

Shouldn't triple buffering be switched on when running v-sync btw?

I have to have v-sync on as well, getting just a bit of tearing with the track ir without it, but the big thing is the prop while flying through a cloud for me, at times in a hurricane I had extreme flickering, gone with v-sync on.
I have it turned on in the nvidia control panel, strangely enough I get better fps without tripple buffering.

Hi there-
strangely, I changed the vsync in the CCC (Vision Engine Control Center) by moving the slider to 'Always On', but it had no effect (and ensuring it was off in-game). I rebooted to be sure the system took note of the change. The flicker was still there, I can only affect the flicker in CoD menu. Not sure if triple buffering makes a difference? I must be stuck having to use the vsync in-game. Some other posts had mentioned radeonPro, and disabling API montoring - do you know if this works? (or is RadeonPro useless with the ATI control panel?)

Try creating a Preset in CCC and launch the game via the preset.

radeonPro has been causing me video issues in both IL2 and in CoD. I cannot use it.

I hadn't even thought about that. Leaving it on with the Nvidia panel and switching it off ingame hasn't affected my game's appearance. Seems a little smoother FPS wise tho that might be my imagination.

To me, these are the most frustrating aspects of IL2 and now CoD. So many tweaks that people discover are scattered all over the internet. I wonder how many other people never find them or how many tweaks I haven't found out about yet? It would be nice to see these stickied on every CoD forum.

Agree. To be honest I tried V-sync the way described above and I still get tearing. So not sure if the settings on the card ever applies.
I'm sure the AA set on the card doesn't work in the game except for lowering your frames.
