580 or 2 6950's

I still don't understand the vram monitoring mechanisms on AMD cards very well. There are 2 weird things:

1) In Shogun 2 the game engine would see 2GB vram usable, on 6870 CrossfireX; this doesn't happen for NVIDIA cards though - GTX580 SLI doesn't get vram doubled.

2) GPU-Z 0.5.5 would read the total vram usage on both cards, where GPU-Z and MSI Afterburner both report the vram usage per GPU on NVIDIA cards.

I'm not sure if these 2 things are correlated. I don't think AMD still uses split-frame rendering to stack up the vram on both cards.

Could you post your log file of Shogun 2 official benchmark (with everything max'ed out and vsync disabled)? (one run with CrossfireX enabled and the other with CrossfireX disabled) The log file is located at:

%APPDATA%\The Creative Assembly\Shogun2\logs

and looks like:

Regarding IQ: there's been debate on the number of pixels in digital cameras for long. Some would insist that there's no IQ improvement going from 12 Mpixel to 24 Mpixel. I agree that 8AA gives minimal improvements upon 4AA, but people just would like to max out everything they can.

For AMD's VRAM monitoring, you have to divide the figure by the amount of GPU's you've got.

I use a 6950 2GB and I get the stuttering in GTA IV.

I used a 5850 1GB and didn't have that problem.

Look, what a coincidence!

Sell your 6950 2GB! Your 5850 1GB is doing better than my 5870 1GB CF. Oh wait, did you force max'ing out GTA4?

This I know. (And I was the first one mentioned it on this forum)

The settings used are like for like on my system.

Look up the definition of stuttering or explain what you meant earlier.

Oh, how clever of you.
