Hello,

I had this error today with my new machine using a brand new 3080Ti graphics card what's wrong ? All works ok when I use the i9 CPU but with the NVIDIA 3080Tii GPU I get these errors

thanks for your help,

Hello Justin,

thanks so much for the quick reply, I'll test this out, the new card is really fast for rendering so I hope this will work

thanks and greetings,

Hans 

Hello Justin,

I installed the 462.65-desktop-win10-64bit-international-nsd-dch-whql-rp driver and now it works perfect, didn't had to reinstall Keyshot 9. Amazing speed for rendering 0,46sec for a 1920x1080px image wow !!!

thanks again for help hope the newer Nvidia drivers will work again with Keyshot,

kind regards,

Hans 

Thanks Justin, I don't have Keyshot 10 yet, I wanted to update when 11 comes out so for now I have to do with v9. It seems to work right now which is strange I had a few crashes and then it started to work again. I'll do more tests tomorrow and let you know how it works out. 

thanks, Hans

Hi Justin , I have a serious issue here, I managed to work with the GPU and safe the file but now when I try to load or work with a project for a client it crashes keyshot most of the time can't even work anymore, this is not good. It worked perfectly with the latest nvidia drivers except GPU export rendering, and why does the new driver cause these export issues ... I'm stuck for now to use cpu only but with a 1600$ graphics 3080Ti card this is really frustrating

thanks,

Hans 

Hey Justin,

if you have workaround for this that would really be help full as this is driving me crazy, it worked well for a few hours and crashing every time I switch to GPU render now it's not the render itself its the switching that causes the crashes in Keyshot thanks, Hans 

Thanks Justin will check this out. 

For now I seem to have found a solution I need to test more but I managed to avoid the crash this way:

1. select 85% CPU usage instead of the initial 100%
2. then switch to GPU 

not sure why ... I'll test more and also your method,

thanks a lot,

kind regards,

Hans 

Hi Justin, yesterday everything worked fine then this morning I couldn't open my project saved with GPU anymore, neither your or my solution worked, really strange, not sure how to adres this I need to finish jobs and am very excited with the new performances of my machine but I cant work this way 

thanks,

Hans 

P.S. new workaround that seems to work is to open a demo file activate GPU and then open my project, really strange, is there any news if Nvidia is going to update their drivers soon addressing the render issues as I didn't had any issues with their latest drivers working in realtime besides the export crash. 

New studio driver seems to have finally fixed this FYI.
