So I am getting this odd issue where I can run everything in GPU mode and it looks great. I render it… the render looks great then it refreshes the GPU and everything gets turned up way past 11… Super bright blown out areas and odd glitches in areas which are pure white. I am running an NVIDIA RTX 4500 ada Generation with the most up to date driver and have 126 gig of ram in my system. If I close Keyshot and reopen the same drawing everything goes back to normal.
Any insight greatly received at this point i will even be happy with the correct words to utter while making a sacrifice the CPU/GPU overlords.

Well Nvidia does an awesome job creating terrible drivers for the past 5 months so I would advise to go back to an old driver since there are also known bugs with Keyshot in all newer drivers.
In the manual they name driver versions but I think those numbers are actually for the normal consumer cards. Last known driver without issues for those is from September 2024.
So I looked for a driver around the same time for the your serie cards and I think you can safely try this one: NVIDIA RTX Driver Release 550 R550 U9 (553.09) | Windows 11
That’s around the same time. And if you install it, pick ‘custom’ and do a clean install. Worth the 10 minutes to try and see if it solves anything.
I don’t have pro series card but really, the past 5 drivers including all hotfixes were terrible.
Thats great I will give it a go thank you. I was going to post some images showing the issue but It turns out I was only getting it with the one file ( which I cant share). It is a large zbrush model (over 2gig), Just out of curiosity I will try decimating down and see if that helps. I did a bunch of updates to things with the help of the dell support guys and ran an anti virus scan and that seems to have sorted out the running out of memory issue i was also getting. but the keyshot one still remains. I will keep this post updated with what solves it.

I hope it helps, I’m not really sure what the actual bugs are since the manual doesn’t mention the exact issue. I experienced rendering stills for an animation suddenly half way too much more time to render, reverting back to the old drivers seemed to solve it.
Since I like to keep things up-to-date, I’m currently using the drivers again from late April but yesterday I noticed sometimes just one GPU rendered instead of both the 3090+4090. When I started again they both came in action. Looking at the forums of Nvidia people are really not pleased in general with the messy drivers. Might be different with the pro-series, I’m not sure how different they really are.
