Marcus,

BTW - could you change the title of the topic (just remove "on Octane 3.03")?
I'll post results for different versions.

Here are latest results for new beta nvidia driver 310.33 - seems that "hallway" problem gone.

Done. And thanks for the benchmark update.

Cheers,

RC2 scores. Hallway problems again:

Hi, thanks for the feedback. Unfortunately I can't reproduce your results here on 1 GTX 690 GPU: The Hallway PT gives 2.03 Ms/s and the Hallway PMC 1.67 Ms/s. A GTX 690 GPU should be a little bit slower than a GTX 680 GPU. -> I think there must be something else going on. Could you try the last WHQL certified driver (306.97)?

Cheers,
Marcus

Marcus,

I did tests again and something is strange. WHL 306.97 gives the same results on RC2 as the beta driver. But I couldn't reproduce results for RC1 on the beta driver - still 1.6Ms/s for the hallway scene (I had 2.31Ms/s). I'll try some more tests and let you know if anything changes.

PS. In PT (with one gpu, my second gpu is at RMA) my computer is so slow. I need to wait seconds to pull down menu or to change any values in Octane. In DL and PMC this is not the case. Isn't it strange?

The hallway numbers still seem wrong to me. With RC3 I achieve on one 690 GPU on Windows 7 the following sample rates for the hallway scene:

PT: 2.10 Ms/s
PMC: 1.73 Ms/s
DL: 18.82 Ms/s

So something is going wrong in your system. How does it behave if you don't overclock? Did you disable Windows Aero, SLI and PhysX? The latter shouldn't make any differences, but you never know...

Cheers,
Marcus
