GPU/ Graphics card not working in vray

[Annelies]

Hello,

I was trying to use CUDA and RTX MODE for rendering in the latest Vray version and it doesn't work. I can see the name of my graphics card and select it but when trying to render it gives an error (device not available). I tried several drivers and nothing works. Then i started trying previous vray versions and now i know that:

i could use CPU, CUDA and RTX in version VRAY 6 (october 4th)
i could use CPU, CUDA and RTX in version 6 hotfix 1
in version 6 hotfix 2 and 3 only CPU and CUDA worked

in version 6 update 1 (may 31th 2023) and any newer version from there on, only CPU worked.
I tried a lot of different drivers (the ones chaos recommend on their website, other ones suggested by chaos staff in forums, newest ones,....) and i don't know which one is best in the end.

Graphics card is Nvidia Quadro M620 

I also downloaded Vray Benchmark 6.0 and in there my graphics card doesn't even show in "V-Ray GPU"

Anyone with this problem who found a sollution? Thanks in advance
