As the SIGGRAPH event is over for this year, there are some quite interesting things that have been revealed through it. Of course the new cooperation between Blizzard and AMD originally seemed to be of some interest at first glance, but IncGamers' StarCraft network site; StarCraftWire.net has let their tech guru loose on some of the papers that were published for the lectures by AMD, and has come to much more interesting conclusions.
The cooperation between AMD and Blizzard surely seems to be more than just a PR trick or getting free graphics cards for BlizzCon, as the documents Blizzard provided themselves hold new, exclusive information about StarCraft 2 system requirements. In this case "only" the requirements for graphics cards, but you will find out a lot more information from this with the help of PC hardware expertise and thorough analyse:
"This is in line with information provided by Xordiah in QA session 13 that the game required Pixel Shader 2.0 support. My article last month, StarCraft 2 System Requirements, contained my analysis in which it became clear that in terms of the GeForce series, the FX line was the bottom grade. This appears to be complete confirmation, the graphical situation was as I expected. I appear to have been near dead on regarding ATI Radeon cards as well."
