Do I need a driver update for the radeon? I downloaded the latest but it does nothing useful. I do not get the advanced controls to turn off v-sync or a/a and this and that. The latest radeon driver does not support the x1600 for macs yet appearantly? Is this true? I can't find anything on the internet about it. I'd really like to see what this puppy has. CHIPSET: Machine Name:iMac Machine Model:iMac4,1 Processor Name:Intel Core Duo Processor Speed:2 GHz Number Of Processors:1 Total Number Of Cores:2 L2 Cache (per processor):2 MB Memory:1 GB Bus Speed:667 MHz VIDEO: Chipset Model:ATY,RadeonX1600 Type:Display Bus:PCIe VRAM (Total):256 MB Vendor:ATI (0x1002) Device ID:0x71c5 Revision ID:0x0000 EFI Driver Version:01.00.063 not running bootcamp, no... sorry forgot to mention the os 10.4.8 i believe. osx yea but my 5 year old nvidia geforce w/ 128 runs better then this card. its like the duo intel + radeon does not cooperate when it comes to direct 3d or opengl?
