Quake 3 3Dnow! optimizations...

[aNtHrAx323]

whenever i play the Quake 3 test 1.08 or earlier, it detects my CPU during that blue screen as an "AMD 3Dnow! enhanced CPU...", but in Quake3 final, it only detects it as an "x86 Pentium2/MMX" CPU. what's up with that? can i manually set my CPU as a 3Dnow! CPU? i have a K6-3 400 @ 112x4.0...

They
1) dropped the 3DNow! support for some issues or,
2) the CPU string given is general or,
3) there never was 3DNow! used.

In all the cases, there's nothing one can do about that. I'm having hard time believing argument #1 because I saw no such a drop in performance that it should have caused.

I think there's no 3DNow! used, and they've never had. That's why they probably removed that separate message for AMD, so that users wouldn't think it's somehow different.

Sounds resonable explanation to me.

I'm not really sure about Quake 3 (I'm not playing this kind of games) but... Quake 3: Arena (don't know if that's the same) is supposed to be 3dNow! optimised: <a href="http://www1.amd.com/products/cpg/3dnow/optimized/"> http://www1.amd.com/products/cpg/3dnow/optimized/ </a>

The so-called "3DNow! optimized" can be different in term of how good the optimization goes. If you're not very particular, any application/games developed and compiled using latest compiler/linker can be the so-called "3DNow! optmized", just because the compiler/linker support 3DNow! instructions. Such generic optimization will not have very good results. Anyway, it's better than nothing.
