VRAM (video memory) has two primary functions: frame buffer and texture cache. The frame buffer is what you see on the screen. The texture cache is used to cache textures for 3D models. Larger texture cache means less time spent hitting disk to load textures. You're not loading textures so more VRAM won't help. --Rich P.
