There is a setting in the config options to setup texture memory. I assume that the higher this is, the more vram the game will use to load and store textures. Obviously then, the game will do less streaming, gameplay will be smoother, and the little snake chasing his ass won't pop up as much.

However, I can find no literature on WHAT that setting should be. I have 2 nvidia gtx260s in SLI mode. Each has one gig of vram. Will the game use 2 gigs of vram, or just 1 gig from one card. And if so, is 1 gig enough for the "ultra" setting?

The purpose of this setting is to balance texture storage in VRAM vs texture streaming from disk. There's a readme.rtf in the root install folder where all the settings are explained a bit more...

from the readme:
-Texture memory size: sets the amount of graphics card memory allocated to textures. Larger values will decrease the amount of streaming that occurs in game and will make the game run more smoothly, but they can also cause the graphics card to run out of memory and even result in game crashes. Choose a reasonable value based on the amount of memory available on your graphics card.
I have 1 GB dedicated VRAM (4 GB with RAM extension) and have set it to large. I have tried other settings but there doesn't seem to be much difference.

Large = 400MB

Very Large = 600MB

This can be seen by opening the *.ini file.

TextureMemoryBudget .........mine is set to 1000, looks better imo.

I'm in chapter 3, and decided to set it to ultra. It runs MUCH smoother. I just wanted to make sure I wasn't sabotaging something else by using the vram for textures. Thanks a bunch for the very helpful answers!

I have seen no performance drop when changing mine from 600 to 1000, and there are no blurry textures.

My understanding of SLi and Crossfire is that card's don't share textures between themselves, instead you have to have duplicate sets of textures loaded into memory on each card. Effectively you only ever have 1GB of available texture memory regardless of your physical count.

I haven't read that before, but it makes a lot of sense. Kinda like a RAID setup for video cards. Thanks!
