I'm having a small issue and I think I have to blame it on RAM somehow.  The game will pause/freeze for a second or so every now and then.  It seems to happen only on a few maps.  My ping is usually ridiculously low on the dFb server (like 20 or so) so it shouldn't be net lag.  I have 5mbit cable and can use any of the defaults from DSL low to T1 w/o problems - I even set the bandwidth manualy to 2048, 5000 and 4096 and saw no difference.

My video card is fine now (x850pro) and I haven't yet figured out how to display the FPS in the game.  I hit the auto config options in F.E.A.R. once I got the new card in and setup and it put alot of the video card settings to maximum.  The computer settings on the other hand are all still set to all minimum by the auto setting.  So like I said, I'm looking to blame RAM or board bandwidth of some kind.  My 1.5GB of RAM runs only at 133 MHz - the only way I can get 266MHz is if I were to have 1GB of RAM due a mobo problem I caused... can only use 2 of 3 slots.

At any rate I'm liking F.E.A.R. alot :)  Even if I do suck and get killed because of the damn glitch every now and then.  The more ppl playing the more likely it becomes a problem LOL
