I'm running Visualize on my new PC and trying to render in GPU-only mode. The process is turning out almost an order of magnitude slower than in CPU-only mode, and my GPU usage is never going above 10%. I know from benchmarks that my graphics card works fine and can get to 100% usage. Any ideas why this might be or how to fix it?

Specs:

Ryzen 5 3600X

PNY Quadro P620

32GB 3600MHz RAM

Windows 10

Visualize Professional 2019 SP2
