Like every other big-name multiplatform game these days, Batman: Arkham Asylum will be appearing not only on console, but on PC as well. Here's what you'll need to run it.
Posting on the game's official boards, an Eidos rep/mod has revealed both the game's minimum and recommended specs to be:
Minimum o CPU: Intel single core 3 Ghz or AMD equivalent o Memory: XP = 1 GB, Vista = 2GB o GPU: Shader Model 3 NVidia 6600 or ATI 1300 or higher
Recommended o CPU: Pentium D 3Ghz or AMD Athlon 64 X2 3800+ (Dual core) o Memory: XP = 2GB, Vista = 3GB o GPU: NVidia 7900 GT or higher
The game will be enhanced for users with multi-core PCs, while it will also - courtesy of its Games for Windows integration - include achievements as well.
