HALO PC extremely laggy is spaceships, caves, corridors, etc.

[sleepy1]

Everytime i'm in caves, alien spaceships and such, it becomes laggy to the point where it takes forever to even turn. However like outside or when i face the wall it runs perfectly smoothly. I surpass all the minimum requirements for this game yet it still lags in those corridors. Is it because of my ram? Help is appreciated. thnx

My comp specs:
1.2 GHz
256 mb ram
128 mb geforce fx 5500
intel celeron

 

[duh-huh-wha?]

im not an expect computer guy but from what i can tell your specs are a little bit low. you should upgrade to 512 ram and a faster processor or try putting halo on low video settings
hope i helped you out a little
