What resolution were you at for those screenshots, Hicksimus?
Those were 1680x1050 I scaled them down a wee bit after by 20% IIRC. The only difference I noted were the zipline to the tower and a bit of the tower before shrinking and the shrink hasn't changed those.
I just decided to hook up to my 42 inch 1920x1080 monitor though and I've got to say Seriously, I've been playing it on a 1680x1050 22 inch of mainstream quality and it just doesn't communicate how the game looks at all. When I switch to the 1080 screen with Dirt 3 or BF3 it's just a bit brighter(and larger) but not a major change to the visual experience. That's not the case with Far Cry 3, by the standards of most games and certainly open world games it's very pretty.
But more to the topic of the thread. The game seems to be holding itself to about 960mb of VRAM at 1680x1050 and it does the same 960mb thing at 1920x1080. I had spikes to about 1150mb at either resolution but I'm not sure if those would adversely affect the gameplay as they were very short spikes in places where I would not be able to explain why they happened.
