BF3 Ultra - Page 2

post #11 of 53
Playing on ultra with a 7970 at 1920x1200, I usually see between 1.2 and 1.7 GB VRAM used. I'll play again soon and confirm. smile.gif

Personally I've only got 1280MB's of vram and I never notice frame rate tanks that are associated with insufficient vram.
Ultra, 1920x1200 resolution, FXAA medium, no MSAA and I almost never dip below 60FPS.
If an explosion is in view (at death), I may dip to 45FPS for a fraction of second but it rises instantly. With MSAA at x2, I still rarely go below 60FPS in normal gameplay and the explosions at death may bring me down to a bare minimum 35FPS for literally 750 milliseconds.

The vram plummet in games are severe when it's seen, usually degrading the frame rate into the single digits. The FB2 engine is most likely opportunistic, loading what it can if it can... if it can.

Phh. Unless your going to run 3 monitors, your not going to see any degradation with 2 680's and 2GB's of vram. Especially if I'm not on 1.3GB. thumb.gif

Processor: Quad-Core CPU
Memory: 4 GB
Hard Drive: 20 GB
Graphics Card: DirectX 11 compatible with 1024 MB RAM (NVIDIA GEFORCE GTX 560 or ATI RADEON 6950)

There's are reason why the recommended is 1GB. The game is optimized around it.
Don't listen to the stink.

Well I figured out a good balance for game play. Everything set to HIGH No AA High Post AA and SSAO. With this setting 55-60 on every map and my temps stay under 75. I can play at Ultra and HBAO but then I'm getting more like 50-60 and my temps will go up to about 85. Also I set a frame rate limit at 60. I use Vsync also. If I set a frame rate limit should I keep using Vsync in game?

hold on how many screens are you using and how big are they?

Same settings for me as well.
except low post. Yeah vsync makes it much much smoother. Better than constant 50-75.

Hey OP could you let me know how constant are the FPS in Battlefield 3 with your GTX 680 SLI? Does it have a wide range, like 90-1xx? Or does it stay pretty constant? This is with Ultra settings of course (or slightly lowered), single monitor, 1080p if possible. It would be great if you are able to test that. I ask because I am thinking of maybe getting GTX 680 SLI.

Smooth to me is 55+ and with the 680's in SLI that is what I get 55-60 all the time on any map at any time. All high settings no AA but HIGH post AA and ssao..

What he said.
With 2 680's on 1 1080p monitor you should never be dipping below 60FPS. Even with vsync on.

I use Afterburners frame limiter because I don't like vsync, so I always have vsync off. I've never used it with vsync so I'm not sure how they jive together.
It all depends on what you would rather have, input lag or frame tearing. Limiting the frame rate to 62FPS takes care of the tearing quite well.
