Thus we chose to scratch the surface a bit harder and crank up the geometry and texture detail to the maximum levels allowed. In addition we pushed both the game and the 32MB GeForce to its knees by running at 1600x1200x32.
We then threw the same test setting at the 64MB GeForce and what we found was a performance increase of over 100%. Before you all get carried away though, that 100% jump was from roughly 10fps up to 20fps, which still isn't all that playable. However, it does give a good indication of what the future may well hold with 64MB vs. 32MB of frame buffer memory. Either way, we liked what we saw in that department and have happily been playing Unreal Tournament (with its slightly less graphically intensive 3D engine) at 1600x1200 ever since.
With 64MB you should be able to run some games at 1280x1024 and 1600x1200 with 32-bit color at playable frame rates. With 32MB you will most likely get single-digit frame rates but with 64MB you will likely see 20+ frames per second. There is also a bit of extra space available in the memory array for the storage of rich and detailed textures (another plus).
