Re: Valve decide what fps is OK
"I *think* that one of the great misconceptions about technology, especially regarding graphics, is that it's revolutionary rather than evolutionary. Remember how people complained about Thief3's and DX:IW's performance? How they performed worse than they looked? I think the *only* difference between those engines and Doom3's is that Doom3 uses specular light maps on everything, whereas those other two don't. Meaning that if you turn off specular in Doom3, you end up with a game that looks the same as the other two, with similar performance."
Just because engines have the same features doesn't mean they perform those features as well. Pre-Release IW did indeed have all the general features of the D3 engine in name, but D3 has defacto superior quality of those effects. Also the polycounts in D3 are WAY higher than those games.
