Craig Zuckerman Posted January 24 Share Posted January 24 Hi, I am using H 20.5.445, windows 11, two high end Nvidia cards-trying to render a single frame, to be about 11" X 8", trying to render 3-4 million particles, rendering very slow, on XPU, have not tried CPU yet, any revelations from anyone, greatly appreciated, Thank you, Craig PS-also, rendering in the scene view takes forever!

curv.u Posted February 10 Share Posted February 10 Could be due to several reasons, hard to say with this few info. Slowness may not depend on your hardware, but rather on your scene optimization. Make sure to: - delete the attributes you don't need in render - remove points outside camera frustum - cache everything just before going to render - check your render samples, ray bounces and limits, motion blur settings If nothing works, proceed with and old fashioned debug: strip the setup to the essentials and take a simple test render for every step. Try to isolate and locate the anomaly. Quote Link to comment Share on other sites More sharing options...
