Direct comparison of 2 vs 4gb at 2560x1600. No performance difference. In fact, the 4gb is slower due to additional latency.
We can go at this all day, I can find tons of reviews showing this to be the case at 2560x1600. 4gb doesn't help you until you do surround. Even in surround you are generally fine as long as you use FXAA or only 2x MSAA.

Yes, but when a certain game eats all the vram, then the stuttering starts to show.I've used all my 1.2gb in Skyrim with mods, and when the vram was all full, i had massive stutterings. And when the vram runs to 0 the application (game) takes memory form the ram, which is a lot slower than vram.

The only way to run out of VRAM is to use a crap ton of mods and a LOT of override SGSSAA. Remember anti aliasing beyond MSAA x 8 uses a TON of VRAM.

You won't run out of VRAM on a single screen resolution ever UNLESS You go overboard on SSAA. You can only enable SSAA in nvidia inspector for most games. See the performance charts above, if you go 4gb for 2560x1600 you are throwing your money away.

There is no game in existence that has more than 500MB for game assets including textures. Anything past that is mostly anti aliasing, and you can go up to 8x MSAA at 2560x1600 without breaking 2gb, easily.

Well i've remember for Skyrim i was using 4gb of texture mods. And the vram was 0, in a small resolution. Used 570gtx.

Yeah, tons of mods can do it or override SSAA. I've seen a lot of performance anomalies with override AA and tend to prefer in game IQ settings, but it works ok in some games.

Also Skyrim has a problem, if you play with tons of mods, the game looks great, but as soon as you play more, the vram fills up because you're exploring the game as you play and loading the textures mods. If the game can do some kind of refresh, when the game loads a new area of the game, for example you explore a area of the game, the vram fills up to 800mb, and when the game loads another area, that previous 800mb to be erased, and loaded into the vram the new textures that require that specific area, and so on....

I say this, because i've experienced good gameplay in Skyrim with 4gb texture mods for 1 hour, and after, it starts to stutter, cuz the textures mods fills up the vram within each area/more areas you visit.

I haven't disappeared yet. I just got here today and explaining my problems with this card playing crysis 2 maxed out on a 2560x1440 res.
You say it isn't the memory, so I will look further into the situation and try to solve it.

it suppose they had a problem wich was solved and then they had nothing more relevant to their interests in this thread.
Or they are just lurking the thread tongue.gif

Xoleras, I don't use any of those mods with nvidia inspector.

Like I said before with Tess disabled on cysis 2 the memory stays the same through out the whole game at 1515. When I apply the TESS the memory grows past 2000 until it crashes the game.
Who knows maybe its a memory leak in the TESS file

It doesn't go past 2000 (I think you mean 2048 right? Yeah I guess so lol) That test is also maxed with dX11 textures and full tessellation.

Crytek2 changes the VRAM cache dynamically but will never pass 2gb on a single screen resolution.
