Hi, just wondering if anyone else has experienced something like this/ has a solution:
I have a basic architectural environment in a scene with some scattering and props etc. All is fine and good, it renders snappy in the viewport until I hop into a camera....any tweaks I make will take an eternity to update and I have no idea why. It's not switching render prims as far as I can tell and I have it set to half res in the viewport (this is happening with Redshift and karma)
thanks in advance!
Render Camera Slow to update but native cam is fast?

This is most likely due to cooking a complex graph after the camera. Is your camera node being edited at the top of a long change of LOP nodes? This would trigger all of these nodes to recook when modifying the camera. For best performance, use a merge at the bottom of the chain to combine your scene, your lights, and your cameras. This way editing lights and cameras stays performant even with more complex scenes.

I was able to fix it for me. It was the Scene Import bringing in the Materials. I had a stonewall with tons of named individual pieces. For some reason the material got recooked on all stones whenever I moved the camera. I deleted the name attribute, so it came in as one mesh and the lag was gone.
