Yeah still no luck. I've tried lower the settings in the nvidia control panel, tried everything from low to max settings, changed direct X levels, but no matter what settings I use I get around the same mediocre fps 40-50. It even drops to around 20-30 sometimes peaks just over 100 only if I stare into a corner of the wall.
I would say it's a bottleneck issue with my CPU but that can't be possible. My windows index rating jumped from 3.5 (javascript:%20validform(this);limited by graphics card) to 4.8 (limited by CPU).
With my old Radeon X1300 128MB, my fps was around 100 constant for HL2 games, on med-low graphic settings. When I used to raise my settings with the old card, the fps would drop until it was unplayable. Since my graphics card with the limiting factor before and I upgrade, how could my CPU be making my fps lower on a better card??
