Hi. I noticed huge increase of render time in new mr 3.7 compaired to mr 3.6 in xsi 7.01. I tried both bsp1 and bsp2, but whatever I did 3.7 looks always slower than old one.
wallclock 0:15:53.95 for rendering 7.5 bsp2
wallclock 0:16:18.30 for rendering 7.5 bsp1
wallclock 0:11:32.08 for rendering 7.01 bsp1
Other tests give me similar results.
