The big VRAM vs clock speed question

[krooton]

With all the brouhaha surrounding VRAM recently, I was wondering if there was a definitive list of graphics options, and whether they are core/memory speed dependent, or VRAM amount dependent?

I know textures are VRAM, and I've seen people state that AA is as well, but I just want to understand which settings/effects are the ones that need to be limited if you are running 1440p+ with 4GB or less.

Good question, I'd be interested in this.

Max Payne 3 tells you the effect, in real-time, on Video RAM as you change graphics settings.

As GTA V uses the same engine I presume it will do a similar thing when released next month

Have a fiddle around with Max Payne 3 though, if you have it...

Image quality, texture quality and AA are pretty much the key options I would have thought?

COH2 for example has all the above, yet reducing image quality has a bigger effect on vram usage than texture quality for some reason.

Image quality in the Nvidia control panel, right?

for 1400p the first thing i would knock down to increase performance is aa as you can get away with it on a higher res screen

Nope sorry, that's in the game options.

i would imagine that shadows will lay on the vram too

This.. HBAO, HDAO and SSAO use up Vram too.

 

[Yaayuh!]

Everything will use up VRAM. The question is, which is the biggest hog.
Also, the more VRAM required, the more general grunt required of the GPU.

I would say Textures is the biggest but the least demanding..
