On the contest page you mention to target 100k p/s untextured and 75k p/s textured. Is there any more info? Like is the stencil buffer really slow in the hardware. or other similar gotchas which might catch out someone not familar with the hardware? Also, a question along the same lines would be, what are the capabilites of the processor. Is refilling the cache slow? Is there a scratch pad of some sort? How fast is accessing memory? Stuff like that. Thanks.
