You didn`t read these tests too carefully, did you?
Quake1: Mediator is the slowest even though tests are being made on V4/V5 gfx card. G-rex is on top here, but gets beat by Prometheus here and there.
Quake2: Prometheus is the best. No Mediator tests here but G-rex and CVPPC gots beaten up smoothly
Heretic2: Slight difference between A4k version of Grex and Prometheus, Mediator is the slowest.
Payback: Funny thing, Grex is the slowest here, Mediator/Prometheus extactly the same.
In overal Mediator is worse in these tests than Grex 4000 and Prometheus.
