Q:Although 3DMark05 only required 128MB of video memory as a minimum requirement, in testing we found that many driver/hardware combinations allocated far more than this for the 3 games tests. Does this mean that you will increase the minimum requirement to 256MB for the next release or stay with 128MB? If it's the former, how would this affect such cards as Radeon 9800s or GeForce 6600 GT’s, which have reasonable shader performance, but only 128MB of local memory?
A: The next 3DMark will require 256MB to ensure that there is no unnecessary swapping going on (System RAM <-> Video RAM). According to our mission of producing forward looking benchmarks to show performance of new hardware, we wanted to take a leap forward, and let the artists have more freedom to create visually stunning content. This doesn’t mean that the next 3DMark won’t run on 128MB hardware, but the performance hit can be quite severe. Several games are already limited by the amount of VRAM (at very high detail settings, which is comparable to the detail level in the next 3DMark), so I don’t see any problems with our decision. It is a known fact that VRAM has an impact on performance if the game is using a load of huge textures & data. Enable AA & AF on top of that and you need 512MB to have acceptable fps. The way we see it is that 256MB is nowadays the standard/default amount of VRAM for relatively high-end cards. 128MB was still a pretty decent amount 1-2 years ago, but things have changed pretty rapidly since. I wouldn’t be surprised if 512MB would be seen as a new standard/default in less than 2 years. Bring on 1GB cards!
