I am trying to set up an NVIDIA Tesla T4 GPU and use its RTX functionality in a raytracing application (Bakery for Unity3D). But every time I launch the app, Bakery tells me it could not find the OptiX library.
I believe to have tracked it down to the driver version being too old (412.16), but when I try to load the GRID 7.2 drivers from the NVIDIA drivers public storage bucket I get an access denied exception.
Do I need to ask for special authorization to get access to this driver?
The short answer is yes. This page will describe that you need a license. NVIDIA vGPU Software (Quadro vDWS, GRID vPC, GRID vApps)
This page, I've set it for the T4 license section depending on what you are looking for. NVIDIA® Virtual GPU (vGPU) Software Documentation
