Hello,

My scene takes long time to start rendering using interactive GPU. It also takes long time to render and update render when I change things in the scene.

When I hit render I also noticed that the graphics card performance rating only goes up to 10% so it feels like the machine is not really using its potential. I am wondering what is the problem?

My graphics card is Quadro P4000 I am using low res (800 \* 450 ) and turned on Material override I am also using fur on the scene for grass btw. Especially for interactive rendering I need faster feedback.

I was wondering if anyone can advise how I can speed things up? Thank you very much.

Best,
