Not necessarily. Just because it's using that much VRAM doesn't it needs it.
For me though, i do hit a VRAM issue with a GTX580no AA for me, just FXAA.
Buy a GTX680 and watch as Nvidia manage to have a 2GB 680 use 20% less VRAM than a 3GB 580 at 2560x1600 4AA on close quaters.
Different GPUs use different amounts of VRAM. Not by much but the 6 series cards do seem to eb more efficient than previous gens.
Try alt tabbing a few times mid game, you'll start chewing into the page file before you know it.![]()
Then just play the game and stop messing about.
Have you had a look at this thread?: Battlefield 3 total system resource benchmarks.
Million discussions on this.
Basically, even 2GB cards have some form of caching going on as excess VRAM is available. 3GB will cache even more as more is available. It doesn't mean it will go to page-file.
I alt tab loads as well and I never have even come close to exceeding 2GB on full Ultra 1080p.
2GB is way more than enough for 1080p. Arguably 1.5GB is OK as well if you disable Aero.
It also won't go to the page-file on 1950~ usage. I run at this level and higher while benching max settings @ 5760*1080 continuously and suffer no page-file streaming slowdowns.
A 2gb card user would be eating into the page file with my settings. Full ultra+4xaa @ 1080p 64 man server.
I alt tab during gaming for a whole host of reasons. Nothing to do with messing about.![]()
This thread is for people to post screenshots in game at various resolutions showing how much video memory their game is using.
It turns into a discussion thread with comments like:
Which are frankly completely factually incorrect. (as confirmed by everyone above)
Messing about or not, if that causes performance issues then you stop doing it or live with it.
As the thread I linked was for something similar I thought you might have a passing interest.
Just wait until Gregster sees this thread and that comment Matt.
I presume it was eating into the page file after a while because if i disabled it, after a few rounds played and some alt tabbing i would get a crash with an out of video memory error.
Disabling aero would help, as would closing battlelog down as they were all using up vram taking me close to the 2gb limit.
That's not a problem any more though with the extra vram my card has.
I don't believe any of what i said to be factually incorrect in my case.
Your comments aren't factually correct because you've applied a generalisation which doesn't hold true.
In fact if you want to apply an extreme at 5760*1080 full Ultra I still don't page file stream or crash so I'm not sure why yours was crashing. Perhaps a problem your end which the extra VRAM is masking.
so can we please drop this now.
2GB is way more than enough for 1080p. Arguably 1.5GB is OK as well if you disable Aero.
