i have 2 Quadro RTX6000 GPU . use passthrough . one(pcisid:1e30) work well . the other one(pcisid:1e78) Partial work .
windows task manager cannot find GPU and openGL cannot find GPU .
Why do you think the GPU is not supporting PT? This GPU supports PT but for Windows you would need the vGPU driver as all datacenter GPUs only support TCC mode on Windows with the datacenter driver.
