Alright I dont have pre and post update stats but I have 10.6.3 and 10.6.4 and MacPro3,1 and MacPro4,1 stats for my system. I could have swore thought that I used to hit 30 fps with 10.6.4 and MacPro3,1 id. I went back to 4,1 because the gpu would get super hot after a sleep cycle, as described by d00d in his native power management thread. Something to do with the gpu not clocking back down after sleep, (or something to that effect d00d will probably explain it much better after me)
* my 10.6.4 scores are post graphics update*
It may be your newer pci3842,1180 EVGA BIOS, I was only able to find the older pci3842,1281 to flash with.
If you have time, would you dump your BIOS with nvflash so that I can test with it?
For X58 MBs and a GTX 285 with degraded performance, edit the AppleGraphicsPowerManagement.kext/Contents/Info.plist's MacPro4,1 section and change Vendor10deDevice05e2 to Vendor10deDevice05e3.
This will keep level 0 low power mode on gpu under low load after sleep and wake, but shader and memory will be stuck in level 2 high power mode.
GPU temperatures before, and after sleep and wake are still less than using MacPro3,1 or deleting AppleGraphicsPowerManagement.kext, which causes gpu, shader and memory to always run in level 2 high power mode.
I've tested this using nvclock with device-properties video string or DSDT video modification, but not with GraphicEnabler.
