One possible explanation that comes to mind is that maybe your refresh 
rate is locked to the monitor's vertical sync.

If you set the monitor to run at 85 Hz you'd only ever receive as much 
as 42.5 Hz if the highest "unlocked" frame rate would be around 60 Hz.

For NVidia cards you can decide if the application controls the vsync 
setting or you can override the default in the Nvidia control center 
(not sure where, currently don't have a Win-PC in front of me but it 
should be easy to locate).

As for the application, the SL viewer has a debug setting called 
"DisableVerticalSync" which - as you probably guessed - has to be set to 
"TRUE".
