I have a very modest iMac, by today's standards anyway, a 24" 2.8Ghz Core2Duo with 4Gb of RAM and a 256Mb ATI Radeon HD 2600 Pro video card, running OS X.6.8. I run Wow on Fair to low settings, same for the SC2 demo (recommended settings), on the native 1920x1080 resolution. And then I see browser games like Quake live, which runs fullscreen in the browser at the same resolution with all settings on maximum. And the game looks smashing. Agreed, the 3D engine from Wow and SC2 is a lot more advanced, with higher resolution textures and higher polygon counts, but when games like Quake live look this good without stressing out your system, I wonder if game developers aren't taking the easy way out and just coding games to run on the latest hardware instead of trying to optimise them to run on more modest systems.
