ive not read the thread, but hyperion not supporting elbox hacky mediator pseudo dma is due to technical reasons i suspect. its not ill will. the benchmarks (the quake demos and compositing) are though cerfully choosen to expose certain aspects where applications actually gain some speed, i suppose. for instance as where compositing on redeon lets the system look fast although accessed through 7mb/s zorro bus, whereas on the other hand the direct bus of p5 gfx cards lets you play framebuffer/non opengl games faster.
i think one should wait unbiased reviews, as well.
