High resolution gaming question

post #1 of 4
Thread Starter 
Does playing a game at a higher resolution ONLY require more VRAM?

For example, if I am able to play a game in 1080p with 200fps, will i retain the same 200 FPS with a resolution of 1440p, provided that I have enough VRAM? or do the other components of the card need to be better as well in order to accommodate the higher resolution?

In case that did not make sense, lets say I own a GTX 680 4gb card, and I am playing a game at 1080p with 1500mb VRAM usage. If i up the resolution to 1440p, and now 2500mb VRAM is being used, will the performance still be exactly the same?

No. while more vram does help with higher resolution, its not the only factor. Core, shader and memory speed is important too.

going from 1080 to 1440 you'll see a little difference in performance with a 680. maybe lose a few frames but nothing noticeable.

No, because GPUs compute per pixel (hence the fact how they have like hundreds of shader cores) so the more pixels you have, the more computations you have to do per frame because you compute per pixel. It also needs more VRAM because you have to pre-buffer and since each pixel requires a set amount of memory the more pixels you have the more VRAM you need.

Hope I helped smile.gif. Taking a CS Graphics course... PITA... really smile.gif Guess no game development for me

Absolutely not. Vram will help, but I would say number of cores and clock speed play a bigger role.
