VRAM for BF4 for Surround

[amenx]

currently cpu bottle neck. oc-ing the 680 (1202 core / 1800 memory) yields no fps gain.

I doubt an i7-3770k (4.7GHz oc) would be a bottleneck at all, let alone at 6k x 1080. It may not necessarily be the CPU if if the GPU yields no more FPS gains at higher oc. Would be interesting to see your results with the 4930k.

good observation. mileage will definitely vary.

most of the time it will be gpu limited. during these times, chances are neither cpu will differ much in performance.

few of the times when it does becomes cpu limited. the 6 core will definitely shine. this should be enough to prevent most of these frame dips.

To answer your second question (how much cache you need) we have found no benefit to having more VRAM than the minimal number it starts with. The problem is testing it is extremely difficult, you don't get to buy a card at 1.4GB VRAM for example to see if it actually has problems, but we aren't getting reports of 1.5GB cards choking so while its absence of data it neitherless suggests that the caching is largely unnecessary.

No one has done a detailed study however, it may be you see more variance with having a lot of cache available, but without any real data or reports suggesting there is an issue its not a big deal if there is an effect. Given the numbers you have provided I would expect a 3GB VRAM card will do brilliantly at the resolution you tested, but its probably too much for a 2GB card.

The OP has made it abundantly clear that HE DOES NOT WANT TO DISCUSS THE R9 290 / R9 290X IN THIS THREAD.

bring this thread back up.

have the notion that the vram management between 680-GK104 could be different from 780-GK110?

for those of you that are running at 5760x1080 surround with 780/780ti.

if you can do a quick bf4 test. be greatly appreciated. max eye candy (ultra setting - not custom setting).

what is initial vram usage at the first 30sec of the game?
and
what is hovering vram usage much later in the game?

thanks.

nvm that last post. GK104 and GK110 are the same architecture.
