vray for rhino gpu rendering errors

[ryan_howell]

Never had any issues until now, but I'm not able to render using gpu, neither cuda or rtx will work without errors. I'm using a RTX A4000 card/Rhino 7 and checked that both vray and rhino are up to date.

Hoping its something simple thats easily identifyable, if not let me know what you need thank you!

After investigating further, it ended up being out of date drivers.

Hello ryan_howell,
I apologize for the delayed reply. Thank you for sharing that your issue is already resolved.

Regarding drivers version you can find this information on the top of this page: https://www.chaos.com/vray-gpu. This is the version that is tested and approved by the developers and how it works with V-Ray, so it can be different from the latest version released by NVIDIA.

In this forum post you can find steps to install drivers in order to have best performance with V-Ray GPU: Installing the recommended Windows Drivers for V-Ray GPU on Windows.
