fpsVR - 1.24.1

The fpsVR has been updated with the following changes:

• The numerical display of the frame time values (above the graphs) now shows not the maximum values, but the average values over the overlay update interval. (In update 1.24 for Oculus headsets, the overlay refresh interval was not used, but a certain number of frames. This was not the right approach. Now a unified approach used for all headsets. This 1.24.1 update uses the overlay update interval for all headsets and instead of choosing the maximum frame time, it now calculate the average frame time)
