Hi,

I wanted to ask why I'm getting higher FPS in my games (street fighter IV AE, battlefield 3, COD MW 3, batman arkham city, etc...)

My Rig

CPU: PDC E2160 OC'd to 3.00GHZ (333 FSB)
Mobo: asus P5Q (p45)
palit GTS 250 512 mb (e-greem edition... i know i got this when i didn't know anything about video cards and tom's LOL)
2x2 GB kingston value ram 667 mhz 4-4-4-12
2x512MB geil hyper ram 667 mhz 4-4-4-12
2x1TB samsung spinpoint F3
astone enforcer case w/ 600w PSU (astone psu also)

the monitors are:

19" LG W1942T (1440x900)
23" LG E2381VR (1920x1080)

windows 7 64bit ultimate sp1 with updates

video card driver: forceware 285.62 64bit

My rig does the same thing, running a Pentium Dual Core @ 3.5Ghz and a AMD 6850, at 800x600 with everything on low in BF3 my FPS is awful around 20-30 but when I run it at 1280x1024 at med-high settings it jumps to 50-60. Doesn't make much sense at all but I think it's because our CPUs are slow in today's standards and the lower resolutions put more strain on the CPU becuase the GPU is pumping frames out so fast at that low of a resolution and the CPU can't keep up. Just my thoughts though.

On the basic level you are correct, its a fair bit more complicated technically speaking but you have the general idea.
Its a mistake a lot of people make, thinking that if they lower the resolution it will all run faster. Resolution bottlenecking is the term for this.

ohhhh.... ok, I'll look into this "resolution bottlenecking!

thanks much R_OON and mactronix for the insight :)
