2 problems with running Halo
for some reason when I play halo1 and halo CE online every thing moves slowly and lags a little, I don't think necessarily it's my internet connection (even though halo does lag sometimes on servers with a cruddy latency) also when I play single player everything including all the characters is very jittery, increasing my frame rate helps a little. I've tried playing with a bunch of settings and while turning everything down also helps a little. I don't see why my computer should have any trouble with this game in the first place.
The other problem is now halo CE won't play on maps that i don't already have (If that is what the filing cabinets next to the server mean, could it be my firewall?)
p.s. my gfx card has the latest drivers and halo has the latest updates although halo CE's update scroller says i need a manual update, which i have installed, so I'm guessing this is just what the scroller says.
thank you in advance.
