I just got into the beta and let me just say I'm really surprised and a little let down by the graphics quality.
I was hoping to try it out with my GTX470 even though it was old (but just the day before it died, artifacting and everything) so I had to revert to my really old 8800GTS (512) and WTF at the game...
A 7yr old GPU is running the game at 1200p with a mix of medium and low, most options are medium, just the texture and something else is low, and at 60fps... I was expecting all low at 30fps or something.
Is the source engine really that good?
