Thank you for sharing this detailed experience. I’d like to share my experiences and its result as my settings with you.
My graphic card is RTX 3060 (12.1GB) so I can’t increase some settings because of rendering time. I wait mostly 100-120 hours rendering time for almost 11.000-15.000 frames but the result is ok for me.
Please look at that, maybe it will be useful for you.
For Path Tracing Mode
Frame rate: 60FPS
Sample per pixel:20
Path Trace Sample:10
Enabled motion blur
for the lightning:
Outside: Noon_Grass environment and intensity mostly between 1200 - 1400 for outside
Inside: Rectangle light, intensity 800-1000
When I use these settings, I have almost satisfied results with my Graphic card.
If you didn’t try these settings before, please try.Regards
