Well, the title says it all. When TF2/Orange Box was new, everything was working properly, basically I had constant FPS and ping. Then came the patch that wrecked performance on some (lowered my FPS a bit) and when that was fixed, I'm now getting the best FPS ever BUT I get insane lag spikes every now and then. This seems to be somewhat related to caching since it only happens per session when I see something new like a new type of enemy appearing in front of me from behind the corner or something like that.
Anyone else?
