Ok, everyone calm down
I can see fps counts spiraling out of control here and this is just how rumors start (we've already shot up from 6 to 30!).
Here are the facts - This is just a quick port of sdlquake with the fixed point changes from pocketquake2 thrown in for good luck. Looking at benchmarks for pocket pc's, they seem to be getting around about 6 at 200mhz, and up to about 10 on certain devices at 400+mhz. Fastest I've been able to get this so far is 6.4 (5.5 without any special configuration) which seems to fit with pocket pc speeds. Now as this is just sdlquake running on linux, it may speed up a bit if it's moved directly over to hardware, but to be honest the speed improvement may be minimal as it's the rendering that's the bottleneck, not input/output.
My gut feeling is that things aren't going to get much quicker until people figure out how to effectively use the second processor, and even then there's no guarentee that the speed is going to increase by much (the second processor could be very, very useful for certain portions of certain apps, but it's not the magic wand people seem to think it is).
