Hehe FPM will only take you so far Dan =).<br><br>There's no way I'm going to type that whole Doom vs Quake thing out again, I just got so annoyed with that question - I mean even an idiot should know the answer =) - sorry that was out of order.<br><br>Anyway in short, Doom is NOT 3D; it's perspective 2D. A simple way of explaining is you take a bitmap and then another and slide them in at angles. That's why looking up in the original Doom caused warping, because you're not looking in 3D, it's 2D.<br><br>Note that OpenGL versions of Doom have been converted to polygons and so the same principals do not apply. I reckon somebody should allow MD2 (quake/quake2 model) files in Doom for the PPC =), if only!<br><br>Now Quake is true 3D, which means it uses polygons (3 Dimensional Blocks), this is nothing like the math involved calculating doom, which is just one big picture. Not only that but Quake has dynamic lighting and lightmaps, all of which are huge math burdens.<br><br>The math required to calculate the 3D, lighting, models and animation in Quake is compared to Doom (just a picture) - huge. The other key problem you have is that PocketPCs weren't designed for this kind of task, so as Dan may have noticed, they use a lot of tricks to do less-used things. The fact they have a technically emulated FPU core is one example, but FPM gets around 'some' of this.<br><br>There's no reason iPAQ's can't have Quake playing at maybe 10-14FPS (standard timerefresh we all use at start point), but going further might be difficult without killing some features. Remember that 10-14FPS would be perfect for Quake.<br><br>If it gets any higher then great, but the CPU still has a cut off point and there's only so much it can handle. Casio should eventually get to about iPaq 001 release speed, can't see them getting higher.<br><br>As I said, PowerVR have a mobile 3D CPU coming out and the new MIPs & ARM 400Mhz CPU's will be upon us by years end/early 2002. It's a wonderful time to be dabbling with PocketPC's, bet you're glad you never got a PalmPilot =). PocketPCs will be the gamers choice, they could even kill the GameBoy Advance if enough software comes out.
