The r_speeds were better than I expected in the base, but they are pretty extreme in the outdoor area. My older machine, which usually handles pb2 pretty well, was struggling out there, and that's without any other players/entities around. I think it's going to be unplayable on many people's computers. The r_speeds could probably be vastly improved with just a few key vis blockers. The problem is everything is exposed, all the way into parts of the base. I noticed when on your boarded ramp, you could stand in one place and get 800 r_speeds, then move over an inch and they'd jump up to like 2200, even though I could not see any additional polygons.
As for the crate in cement... isn't that a metal texture? And, whoa, bug, what video card do you have? That texture filtering is trippy!
The broken bricks look good, but they seem out of place. The map has an overall medieval appearance, and then there's just this random chunk of modern brick in there. It just looks inconsistent. A stone texture would fit better, but then it wouldn't line up with your brushes.
I really, really dislike the fact that a trick jump is required to obtain the second flag. Especially when it's worth more points than the main flag. Competitive play should be about strategy and teamwork, not jumping sk1llz. Not that the jumps are difficult. They're just a nuisance. They're something that could potentially cause you to lose the game because you screwed up on a stupid jump. If you just throw in a simple ladder or box pile at the access points -- something a little slower, but accessible to everyone, it would take care of that.
