Ok for a FPS under 1mb what do you think you will get? Something from the days of atari right? Well try more along the lines of HL.(not quite but still. )
Take a look at this:
http://theprodukkt.com/kkrieger
The "official" minimum specs for .kkrieger: chapter 1 beta are:
* A 1.5GHz pentium 3 / athlon or faster.
* 512MB of RAM.
* a GeForce4Ti (or higher) or ATI Radeon8500 (or higher) graphics card supporting pixel shaders 1.3, preferably with 128MB or more of VRAM.
* some kind of sound hardware.
* DirectX 9.0b.
however, there's bad news: due to an unnoticed build error in the actual released version of .kkrieger, there are severe shadow bugs on Geforce4 and Radeon8500/9000 cards. the game should be playable, but everything will be way to dark.
Cool to play for a few mins. For a blink of the eye download what do you expect.
