Pixar's RenderMan & Maya - NVIDIA Quadro K4200
Hi everyone,
I am not totally sure if this is a graphics card issue, but I will post it here to get started anyway. I will also be posting again over in the Official Pixar forum, but would like to see if anyone can help here also.
I have recently wiped my PC and reinstalled Windows 7. All drivers/Windows updates are installed. I have Maya 2018.5 installed along with RenderMan Non-Commercial version 22.3.
This latest RenderMan has been totally re-written and is meant to be blazing quick in IPR mode. I have seen demos of it upon release and it is indeed, the team did an amazing job with this release, it does seem a lot zippier and responsive. However...
I am running IPR and it is running fine, I can do material edits, move geometry in the viewport and it all updates fine in the IPR window. But, after some minutes, it begins to stutter and becomes nowhere near as responsive as it should be. For example, I had a piece of geometry and went to hide it, then Maya and the IPR froze for approx. 4 mins, then came back to life, reflecting the change. But this is meant to be interactive, on the fly updates. (This was a bare bones scene with a ground place, a few spheres, cubes and a torus. With no textures! A brutally simple scene.) It is a bit random, it will run normal for another few mins, while I move the camera around the scene. But, then lets say I go to move the position of a light, it freezes up for about 20 or 30 secs, then decides to move the light. Instead of showing an instant update.
Can anyone suggest any ideas of how I would go about fixing this? I know that it is definitely not meant to behave in this manner. It is meant to be WAY more responsive.
Thanks,
Paul
