dude why so quiet

Well, the xbox is much more powerful than the PS2 so it'd be even harder to emulate at full speed... even if it's running a modified version of DX 8.1....

Yes it's probably easier to emulate because like I said above it uses a modified version of DirectX 8.1 but fact remains that's it much more powerful than the PS2 / Reason for Turok, well there could be many reasons here are 2

1. Turok isn't exactly the most impressing game on the xbox and I doubt it uses the xbox resources to the fullest.
2. The author has probably focused to make this single game as fast as possible.

Well, most people don't think Halo 2 is crap ~_~ , and it's not just x86 in a box , As you can see above I wrote that it'd be easier to emulate because it uses a modified version of DirectX 8.1, and of course like you said it also uses a intel x86CPU. However it's still not just a PC in a box because the memory arcitecture for example is different.

So what? And the PC is much more powerful than both of them.
The interesting thing is the amount of overhead emulation creates, and that should be far less for xbox-emulation than for ps2-emulation (or every other emulator).

Of course overhead is important, but if something is twice as powerful as something else, and creates half the amount of overhead... it's equally hard to get to run at the same speed :O

Touché my statement was not meant as a conclusion but merely as an explanation to what I meant, even if the xbox creates much less overhead.. it's still hard to emulate at good speeds because it's faster. I'd very much like for someone to prove me wrong and write a fully working xbox emulator within a year, or two though
