Does anyone actually find it surprising that the average videocard would be GF2 (Probably GF2MX) level? Goes to show how a lot of people on this board are more 3d theorizers than 3d gamers.
Some people I know from Warcraft III are still using TNT2 and VooDoo3 level hardware! There are plenty of people with GF1/GF2MX/Radeon7000 class videocards, and lots of people with sub-GHz CPUs. And that's not even that bad - Warcraft III is much more graphically intense than Starcraft and Counter-Strike, and
hundreds of thousands of gamers still play SC and CS each day. And don't even mention "The Sims"!
Given the sheer number of people playing games like The Sims and Starcraft, I would not be surprised to hear that a GeForce2MX is
more than the average 3d videocard. Heck, a 90 MHz Pentium with no 3d accelerator at all can play Starcraft comfortably. And for all you can say about 2 year old scores cluttering the ORB, anyone who would actually download and submit 3dmark scores probably has a well-above-average system.
However, the fact that 80% of the population cannot hope to run their game does not deter people like Tim Sweeney and John Carmack from making good graphics. After all, First Person Shooters only appeal to a certain demographic group (one very different from the "The Sims" crowd) and that group is far more likely to have cutting-edge hardware than the RTS or RPG gamer. The fact that ~80% of the gaming public has extremely outdated computers has not been a show-stopping roadblock for 3d engines in the past, and is not a big roadblock now.
I find it extremely heartening that both nVidia and ATi are now extending DX8 support (DX9 in the case of NV34) to the low end. Today's low end cards are going to remain in a lot of computers for the next 3 years - they, like the TNT2 for games released in 2002, will be the minimum system requirement for games in 2006.
