Hello @JabbaTheNut,
When this first arose, it affected all NVIDIA cards, quadros included. Just to show you how much I was following the cards affected, here is my internal spreadsheet for the problem that I updated based on all of my forum cases and sent to QA. (Attached) You can see it was basically all cards, not just GTX's. I don't think the quadro specifically would solve your freezing problem, unless the different drivers for it fixed some kind of driver issue.
NVIDIA released a driver update in July that addressed the issue and fixed it for (I thought) everyone. The couple folks in this thread recently are the first I've heard of any problems since those new drivers were released in July. My first thought is to try to run some kind of driver removal and wipe any traces of your current drivers out, reboot, and install the latest versions. At home I do not install parts of the NVIDIA drivers that I don't use. For example, the sound driver, the vision (whatever that is), and geforce experience. Given this this was driver related in the past, I think that's a good place to start looking here. If you want, you can email me your event viewer logs to [email protected] and I'll look for any issues in there. You might also try the suggestion for Bostlund in the 2nd paragraph below, might be power related.
Hello @bostlund,
The locking up issue you are experience during renders was the result of a Vray update, I believe it started with 3.2. (Maybe 3.5) There is a forum thread about it at the Chaosgroup forums, might be worth a peek. Although it isn’t part of Autodesk, this post may have information that could help you. Please use best practices to safeguard your systems if you decide to adopt any of the suggestions on this site.
I have never seen anything like that screen stretching problem before. It's affecting your bg, so it's a hardware/driver/OS issue no doubt about it. Are you running in SLI or something? Maybe not enough steady power to the 12V rails? It feels like a power problem to me. Please try to go to the NVIDIA Control Panel ->Manage 3D settings->Global Settings->Power Management mode and change to “Prefer maximum performance”. This seems to solve issues like this for many people. Also setting Windows to maximum performance can help a bit too. I wonder if these would also help @JabbaTheNut.
EDIT: Grammar, flow.
Best Regards,
