60fps unplayable? Damn we're spoiled. The last 4 years in the graphics industry have been amazing.
I remember feeling like a big shot playing HL1 at 800x600 on a 8meg VooDoo2. It got a littler choppy occasionally, but going from a 233 MMX to a 350P2 and 64 meg ram fixed that.
Seriously though, we've been spoiled by the incredably advances made in the last few years. The revolutionary GeForce series (credit where it's due folks) allowed us to crank the resulotion so high and still have astronomical frame rates, it's become unthinkable now to play at a sissy rez of 800X600.
I really thought the resolution VS AA argument was settled. XBox games look great at low rez because they're using AA. Blame the Radeon 9700Pro. It allowed us to crank up the rez AND pump up the AA.
Right now, me and my guys are playing Serious Sam SE co-op, mental of course. We like Mechwarrior 4 Mercs(the mech lab is half the fun), C&C Generals and one of my guys is really into Ever Quest. Picked up the latest Unreal, but it didn't really grab us.
As far as FPS goes they all play completly smooth, don't have exact numbers, but I've not noticed any slow downs on their machines. They have AXPs 2400+ , 512 meg on KT33 boards. (Hmmmm, that's not bad. DAMN !! Daddy's gotta upgrade his rig soon)
I also told them not to change any of the settings I configured in the driver, 4XAA and 8XAF. They play everything at 1024X768.
AnyHoo, as far as HL2 goes, that really otta do it. If it's gotta be 800X600 with 2XAA , then so be it.
