GPU vs CPU "will it fit"?

richardrhinson

Is there a simple way (menu option, add-on, what ever), before hitting "Render" to see if a scene will process via GPU, or drop into low gear and go into CPU?

Unfortunately no, it isn't possible tio know.

If you disable the CPU render fallback; "Render Settings/Advanced.../Allow CPU Fallback", third from the bottom of the pane, then that done Studio won't waste time going to the CPU, so you get to the black render quicker.  Other than that it is intuition because the GPU has a lot of options for decreasing memory use as things get tight and it will use them (at least with the latest implementations of the NVidia stuff).

Simtenero's iray memory assistant isn't 100% accurate, but it's a prety good 'guesstimate'.

Haven't tested it in 4.20, so caveat emptor.

Thank you!  I'm loving this Tool.  Wish I'd thought to ask the question years ago.
