. I agree it seems like too much of a decrease. I haven't tested any other projects yet but I will because that's a pretty significant issue IMO. Please make sure that SLI is disabled. And could you send us the scene? Thank you very much in advance.haknslash wrote:Yea I'm seeing huge differences in speed from 1.5 to 2.0 (demo).

When I bought Octane..... yadda yadda, ranty bollocks
I just realized, that in the demo version the "use priority" option (see File -> Preferences... -> CUDA Devices) is enabled by default and according to your screenshots the render priority in your scene seems to be set to "low", which would explain at least some of the slow down.haknslash wrote:Yea I'm seeing huge differences in speed from 1.5 to 2.0 (demo).

I have checked and it is at the defaul use priority setting. I'm not sure why it shows otherwise but the setting hasn't been changed and everything is "out of the box default". I am almost positive use priority is selected on 1.50 but I will double check when I'm back in the office. SLI has always been disabled unless 2.0 upon launching is changing my Nvidia Control settings somehow and then reverting when I launch 1.50 (I don't think this is happening). I can send you the file Monday next week for testing. Thanks for looking into it.abstrax wrote:I just realized, that in the demo version the "use priority" option (see File -> Preferences... -> CUDA Devices) is enabled by default and according to your screenshots the render priority in your scene seems to be set to "low", which would explain at least some of the slow down.haknslash wrote:Yea I'm seeing huge differences in speed from 1.5 to 2.0 (demo).

Could you set the "use priority" option and render priority to the same settings as in your 1.5 version and try again?
Sorry, that I didn't think of it earlier...
The demo version doesn't load or save preferences, so your 1.5 prefs are ignored. It's default is: All GPUs use priority and the default render priority is "low". Earlier today I uploaded a new demo build, where the default render priority is "high". Let me know how that goes.haknslash wrote:I have checked and it is at the defaul use priority setting.
