Resolution versus Vram

post #1 of 3
Thread Starter 
Hey Gents,

I am looking to upgrade my 1080p tv/monitor to an actual 1440p monitor. I have seen contradicting arguments about whether moving up resolution will have a large impact on Vram. In my case I run all my games at the highest settings possible, except Witcher 2, and only modded Skyrim gets close to the 2560MB of Vram my graphics cards have (gets up to 2300MB with current mods). Usually I have head room for GPU power, with V-sync the cards usage is reported around 60-80%. My concern is that if I upgrade my monitor, will I have to start backing off on the graphics? If that were the case, it would make upgrading pretty useless. Though with a 1440p monitor I would probably turn AA down or off.

My setup below, check my signature for more detail.
CPU: AMD 1100T
GPUs: 2x GTX 570 2.5GB SLI

I used to run 1440p on a 1GB CF setup, so I have some experience thumb.gif

It all depends on the game engine. Some well written game engines do exactly what they're supposed to do, and scale VRAM usage with the amount the card has. Textures/LOD get scaled dynamically.

Some games (Bioshock Infinite is the most recent example I can think of), require some ini tweaks to keep VRAM usage in check, as they're poorly configured by default.

And other games (modded Skyrim madsmiley.png ) have memory managements engines from the depths of hell itself, and don't run well without overhauling the memory manager entirely (Fortunatley, ENBoost does exactly that biggrin.gif )



Anyway, 2.5GB is absolutely fine for 1440p. You'll find heavy AA is completely unecessary at this resolution, and that light SMAA or heavier 2x MSAA will do the trick in any game.

Thanks for the info, looks like I am going to blow some money on a new monitor!
