You can check out my sig to see if I should be getting slow framerates. I don't think I should. On certain maps I seem to get slower and slower (MorpheusII, Coup). I am using the U4E mod and all custom models. Explosions and large gunfights tend to tax my PC to the limits. I really shouldn't be having these problems should I? Sometimes it will hang for a second and then catch up and sometimes it will lock up completely! Thanks for any help. I'm using UT v436, Glide. Should I be using D3D?
