Describe the Bug
The nvenc sunshine is using is being configured to use preset 12 which is not present this configuration. I verified the system version of ffmpeg does support it, but sunshine goes through shared libraries or some other mechanism and these seem to be what are failing.
Expected Behavior
Prerelease works with 600 series nvidia drivers, as nvenc and similar dependencies have demanded this previously. nvenc fails so it falls back to vulkan
