pl_frontier is a great custom map.
i love that place. I play pyro on defense there. There are a lot of wedges in the rocks to hide in :)
I have 768MB of RAM, and my game is still laggy. Except for this one map, badlands capture point, ran so smoothly except for when i look at buildings... Dam sentry guns lag and shoot at the same time... Honestly I think it is my internet :( My connection was never fixed by the computer technician. Also when he came over a couple days ago he tried to fix this comptuter, 2 problems, diskette drive 0 seek failure and a popup that cant be blocked. He didnt fix either.
