Highest vram usage you've ever seen?

Was just playing through crysis (dx10 very high) and defeated the end boss, in eyefinity at 4800x900 the vram tipped the scales at over 3960 megs, think the highest it got to was around 3970 :eek:. Final fight was a slideshow around 12fps, though ive just realised i had crossfire disabled. I think at 5760x1080 it would easily crack over 4 gigs.

Anyone else (eyefinity or otherwise) know of a more demanding game?

theres also a bug on the last level of crysis in dx10 mode it was a slide show for me too on a ati 5970 at 1680x1050 (my old monitor) i had to keep restarting the level until it fixed itself.. and i was getting full fps again. it was a common bug even after the patchs so perhaps that also caused the slow down.
 
About 1400MB or so I think on Crysis... that's @ 1080 P with AA.

leinad, your signature is a line too many BTW, could you please edit it to four lines. :)

Stupidest question ever, what actually happens if say your using a 1GB card and your using 1.4GB? does fps reduce or something daft?

This is what I am interested in finding out aswell. I have 5850 and it has 1GB of vram. So if the vram usage went above 1GB, would we see stuttering, lines across the screen, game slow down etc?

Depending on the game & other factors of how far past you go you can lose a few FPS, 50% or massive 75% & even plummet to less than 1fps like what happened to me with GRID.

Fps will drop quite a bit because your system will result to using your actual system's memory for the remaining amount which obviously isn't as fast as your gfx card memory.

Hmm. So it is just like with system memory aswell in that if the system memory is full then the remaining amount needed is fulfilled by the introduction of virtual memory.

Would this also happen in the case of vram in that if you required some more amount and system memory was also full, then graphics card will resort to using virtual memory which is hard disk based?

Well it's not really 3,960MB.

As you're using crossfire you have 2x2GB and not 4GB.

It's the same as a single 2GB card using 1,980MB which is possible if you have very high settings.
