Not so sure about that!

This is just a humble Quicksilver, running a passively cooled GF 6600GT which doesn't even have an external transmitter!

...and no, it is not the Quad behind the corner, driving the display! 😝

Its only been a few years, but just noticed the non stock cpu heatsink on the QS. What CPU are you using ?

Cool monitor :)

The thread adds notes about a method to do the benchmark more quickly (do it manually using the mouse wheel) and how to increase the score in Leopard back up to Tiger levels by putting the display to sleep for second.

Very interesting. I noticed the fan going to full speed after sleep and it annoyed me but I didn't think it would have any effect on performance.

EDIT: can confirm that it works, was able to get the 12700 score with the display sleep.

I had a major power throttling experience on my 7800 GT (Flashed OEM ROM v2152.2) in my Quad G5 as documented here, which was resulting in a consistently low OpenMark score of 1254, under both Leopard or Tiger.

I tried the display sleep technique above and I couldn't hear (or see) the fan spin up as reported by others, but I did finally resolve the issue by changing the performance profile in System Preferences. The GPU now benchmarks exactly 9331 as reported by many others.

Something had locked the GPU state in its low performance mode, which was not addressed by PRAM or NVRAM resets, so I just wanted to share, that if anyone is seeing lower than expected benchmark results, then try using Energy Saver to toggle between Automatic/Highest/Reduced and see if this makes a difference.

I am able to see the single sphere render window jump from ~750fps to over 1400fps when I switch between Reduced performance mode and Automatic or Highest (while in it's throttled state, this was sub 100fps).

Are you unable to get the expected 12700 in Tiger or in Leopard (after display sleep)? (7800 GT Mac Edition 2152.2)
Use the mouse wheel to select 9124992 triangles. It should read 13 fps instead of 9 fps.
Or select 12700800 triangles which should read 9 fps.

Thanks for the response. I rebooted into Tiger and set System Preferences > Energy Saver > Processor Performance to Highest, then launched OpenMark and reran the benchmark. I am now seeing 12700 (at 1680x1050x32). I can confirm the 9fps at 12700800, and 13fps at 9124992.

So it seems a score of 9331 is consistent for Leopard, and 12700 on Tiger. Which is not surprising. The single sphere render (on a fresh app launch) now gives ~1600fps tops, which is up from ~1400fps on Leopard.

I didn't need to display sleep to achieve this – can you confirm you get the same behavior by setting the energy saver performance to highest? Or is it only achievable with the display sleep/wake method?

You should be able to get 12700 in Leopard after a boot with sleeping the display for a second.

My Processor Performance setting in Leopard was set to Automatic. Changing it to Highest had no affect on the benchmark even after a restart. Sleeping the display for a second does increase the fps from 9 to 13 for 9124992 triangles.
