Yes all of them were running. You can see in the lower right corner of the display port ;). 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.

Will the 3DS max plugin demo work with the standalone 2.0 demo? I'd like to test it but I don't want to mess up my existing 1.5 max plugin. I suspect speeds would be the same regardless if it's the standalone or plugin version so I'm not sure if its even worth to test.

Octane Render 1.50 (standalone)
336.43 Ms/sec @ 8 seconds (0:24 seconds est. time to reach convergence of 16,000 s/px)

Please make sure that SLI is disabled. And could you send us the scene? Thank you very much in advance.

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.

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...

Yes, when I tried 2.0 with the demo and unchecked "priority" I got the same ms in benchmark as with1.16!

I can't imagine the demo is faster than standalone

I'm slightly disappointed in this, hopefully this speed decrease becomes less and less as future updates happen. However the features are a great asset. Hopefully particle/volumetric rendering will be in 3.0. And hopefully without the speed losses :P

Yep, we are working on it all the time.

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.

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.

Thanks,
