HOT TIPS to reduce Octane crashing After weeks of relentless crashing (like several times an hour) I raised a ticket with OTOY help team. Bepe (great guy) got me to do several system checks & diagnostics, and discovered a list of things to tune.
The changes we made have reduced the crashing dramatically so here they are. I hope this helps anyone who is also suffering a lot of crashes.
Make sure your windows OS is up to date (I upgraded from 1809 to 1903). You will need to do this in order to run the latest drivers.
Only use Nvidia 'Studio' drivers, not Gaming or Beta drivers. Nvidia make you choose which type when downloading from their site, so in the Manual Driver Search panel, click the 'All' menu - here you will find Studio as an option.
Disable 'OpenGL' in Octane. This on by default (and probably shouldn’t be!). It is done in two places:-
Octane Settings > Other (tab) >'Use Octane for Opengl previews' (uncheck this).
Octane Dialog > Options (menu) > 'Opengl previews' (uncheck this).
Make sure your Devices (GPU) priority is set properly. In 'Octane Settings' go to 'Settings' (tab) > Devices (tab).
Set Priority to LOW
Make sure all your GPU cards are checked in the first column
In the Priority column, only check the GPU that is running your monitor(s). Leave the others unchecked.
Make sure that your GPU cards are not overclocked. Check your part number as some come pre-overclocked.
Disable any CPU booster application (eg Intel Turbo Boost).
