I have a serious performance issue when playing Oblivion. The game will pause for 1 sec, go for 2 sec, pause for 1 sec, etc. This even happens on the first loading screen when the start the game where it says 'Bethesda Softworks' so it's not a simple FPS problem. I've tried updating my video drivers to the new Nividia ones that are optimised for Oblivion, updated sound card drivers, re-installed the game. Nothing changed!
Here's my system spec:
Athlon64 3500
ABIT AV8
Geforce 6800GT
1GB RAM
Audigy 2 Sound Card
Any ideas?
