I've encountered a couple of minor glitches in DKS so far and thought I might report them.
1. Sound stuttering / looping when loading screen showing up (example: leaving a house).
2. Fell through the world twice on Sentinel island just outside the cave entrance to the tower while fighting Doret/Goret or somesuch. Around where those planks are on the ground.
I'll post my computer specs once I get home, but off the top of my head:
CPU: Core 2 duo (3ghz)
Memory: 4 gig
Video card: ATI 4770
OS: Windows 7 32 bit
HD: 128GB SSD (OCZ Vertex 1)
