Nvidia GPUs for BF4 with Ultra settings at 3k Resolution

[Linkdrive]

At 5760x1080, a single GTX 780Ti pulls around 30fps average on Ultra. If we assume that BF4 has at least a 70% performance gain in dual SLI, then 2x GTX 780Ti might be enough to play BF4 at or near 60fps with a decent overclock on Ultra settings.

I don't think it would be wise to move to triple 1440p monitors. 7680x1440 is 1 million pixels shy of being twice the pixel size of 5760x1080. (11,318,400 pixels vs 6,220,800 pixels, an 81% increase) That said, triple 1440p screens at 2xMSAA will likely perform worse than triple 1080p screens at 4xMSAA. The best way you can try to judge the kind of performance would be to increase the rendering resolution of BF4 to +180%.

"Ultra" is a complete misnomer as each site seems to vary the levels of AA (especially mixing levels of post and msaa), making comparison difficult

MSAA kills at that high of a resolution. If you turn MSAA down and turn Post AA to low it look a little better than no AA at all and you will have 0 issues getting 60 fps.

for BF4. ultra setting is a preset. no way to mix levels of AA.
only the custom preset - one can mix n match.
sadly. high setting preset on yields 31fps (10 fps gain).


will test the bit-tech method and report back.

Now that is strange, I really feel like something is wrong. At 31 fps at high with 3 680s you are getting lower than bit-tech did on their 690 -- and that was at launch. FPS has come up in BF4 for all cards since then. Have you tried a reverting drivers to an earlier build and/or WHQL drivers? Your CPU is no slouch overclocked like that, so it cant be CPU bottleneck

Have you tried just 2x 680 SLI in case there is some weird BF4 issue with scaling to the third?

will try both 680 x1 n 680 x2 and report back.

Another note, apparently with the March 31st patch in BF4 they added two varieties of frame pacing built into the game. Now I'm not clear on whether one/both are Mantle-only or if they are built into the DX side in some manner as well? http://battlelog.battlefield.com/bf4/forum/threadview/2955065227487387474/
It seems from that thread to be Mantle only but I wonder if it impacted the DX pipeline regardless

It only relates to Mantle, as the driver for it no longer implements any form of crossfire AFR, its up to the game developer to not only implement AFR but also to frame pace with Mantle. The new flag (all the references to the frame pacing in the patch notes) only impacts Mantle according to the test article at pcper.com.
