Has anyone else encountered this issue? It started about 2 weeks ago, in playback suddenly the picture would freeze, while the audio and the time line keep playing. Then an error message comes up "Session freeze and/or feature conflict detected with the current graphics device." telling me to save and close the program. When I reload the file and hit playback the message comes up again. The project is currently showing Video Memory as 1.2/11.1GB which is normally not an issue.

Previously, I installed a new graphics card in early Jan GTX 1080 ti and have had no problems till now and the problem only occurs with Iclone. Researching this on-line it appears a common problem with the 1080 ti. I have followed all the recommendations updating graphics, audio and windows drivers and iclone is up to date, but still the problem persists. I have also tested removing each of the models and props in the scene, but it makes no difference.

Timing wise the problem seems to have arisen around the time of the latest GTX driver update, but also coincides with a lot of RL updates, so while I think its related to the graphics card, I cannot be sure and iclone appears to be the only program affected.

Anyone else experienced this or have some ideas on what I can try next?
Cheers,
Tony

There seem to be problems with the latest Nvidia drivers and iClone. I have a  GTX 1080 ti with an older driver version (417.35) and things work OK.

Yes, I have been having trouble. I've added this to the Feedback Tracker and adding it here too in case someone has something to offer.

Over the past few days, I've been dealing with the same Session Freeze problem: Session freeze and / or feature conflict detected with the current graphics device . The program will be shut down now . Please save your project to avoid loss of data . By restarting the program the faulty graphic features will be removed for enhanced stability.
The full screen render proceeds, runs a couple of frames (none to 3) at expected speed, then runs through the remaining frames quickly without any visual movements. Essentially, you end up with a static image in the video. It doesn't effect audio. It's purely the render image.
Whether, waiting or cancelling the render, the edit window whites out (disappears) and the error message appears.
It's become quite impossible to scrub the timeline, unless you go to minimal view. That's fine except for viewing shadows. The playback in other setting is glitchy.
I don't use IRAY.
Much like others facing this one, it's a repeat performance.
Close the program > Open the program > Open the project > check > render > crash error > end.

I've had no problems rendering until now. Running NVidia GFX 750.
I've tried a few suggestions from different people to resolve, including rolling back the drivers to 417.35, downloading and installing the IC7-CC3-Rov-OFF-2 reg, and in desperation tried adding the Static Noise (Smooth Color Banding) to Post Effects.
I have rendered a previous few versions of the section of the project I'm trying to render again. It's a mere 380 frames.
I've rendered up to 2200 frames previously, even a week ago. Again, this has only been happening over the past few days, maybe 5.
I'm not having problems with any other software.
There isn't any point sending you files as the problem seems to lie with some kind of conflict somewhere.

Has anyone come up with a solution - is there something else to try?
3/4 of the way through a project... hoping for some joy.
Just to add, I'm using iClone 7.41
