http://www.insidemacgames.com/news/story.php?ID=20703 this is what they say: Requirements: Operating System: 10.6.8 (Snow Leopard), 10.7.3 (Lion) CPU Processor: Intel Core 2 Duo (Dual-Core) CPU Speed: 2.4 GHz Memory: 2 GB Hard Disk Space: 3.5 GB Video Card (ATI): Radeon HD 2600 Video Card (NVidia): Geforce 8600 Video Memory (VRam): 256 MB here is a link from 2006 with the original sys req: http://www.macworld.com/article/1049219/quake4.html According to Aspyr, Quake 4 will require Mac OS X v10.3.9 or later, G4, G5 or Intel-based Mac running at 1.67GHz or faster, 512MB RAM, 3GB hard disk space, ATI Radeon 9600 or Nvidia GeForce 6600 or better 3D graphics with at least 64MB VRAM, DVD drive, and TCP/IP-based Internet or LAN connection for online play, which will be cross-platform. LOL WTF???!!! i instantly noticed something was wrong when i read that it requires 256mb of vram because my imac from 2007 with 128mb of vram can run it smoothly... not just that, but also the processor info doesn't match up! i know almost everyone nowadays has an intel mac and that they probably recompiled the game or somehting for the digital release... but come on! what's going on here?
