Like AMD, NVIDIA has updated its gaming graphics drivers to bring support for DOOM VFR. This version brings back the NV Tray too.
The following issues have been fixed:
– [NVIDIA Control Panel]: With cross-adapter clone mode enabled, the NVIDIA Control Panel crashes or hangs when you select With the NVIDIA Settings from the Adjust Video Color Settings page. 
– [Optimus][Notebook][Wolfenstein]: The game crashes.
