The difference between the graphics of Episode 1 of Half Life 2, and Episode 2 is huge!
I didn't expect my video card to take such a hit, especially with the flash light on (It now supports shadowing of other objects when you shine at them against walls, etc. Never seen that in a video game before)
With the flash light on, my FPS takes a big hit, to like the 30's with all settings on Full (Textures on Very High), including resolution at 1680x1050 at 4x AA.
I may have to lower this, to like 2x AA.
But wow... I was getting in the other versions over 100 most of the time, but to be suddenly getting 30-50-60 (Around 100 in buildings) fps max is a rather amazing feat for a revamped Source Engine.
Half Life Episode 1 wasn't amazing though, and completed it within around 4-5 hours, if that. This ones supposedly much better
