My machine: Pentium 4 3.2GHz prescott, 9600GT OC, 4GB OCZ PC2-6400 on XP Pro/DX9c. F3 settings: 1680x1020, 4xAA, 4xFF, all other settings on "high." No vsync. Just playing around outside Megaton, fighting the critters and doing other such simple gameplay yields 15-20fps. Loading times are very fast. I am a sucker for eye candy but I know my specs aren't top, so I decided to lower resolution & graphics settings in hopes of hitting at least 30fps. To my surprise, going to 1440 res & medium settings did not improve my framerates more than 2-5fps! My questions: what are your specs and performance average? Might upgrading my aged prescott improve framerates? Any of you find a good 'sweet spot' on performance/visual appeal? Cheers!
