I have an Athlon 3200+ and ATI 9800 Pro. CPU runs at 40% usage max. Some scenes (i.e 1080i LOTR TTT first scene when camera goes around mountain views) seem to run at a low frame rate. I don't think it's my PC since CPU doesn't even sweat. Is this normal? Is there a solution to this problem? I tried it on VLC and WinDVD - both show the same problem.
