When the caching of video RAM was enabled, the framerates recorded had a
slightly larger variance of 62.7 fps - that's for a high of 91.7 fps
and a low of 29.0 fps. When the caching was disabled, the
framerates were a little more stable with a variance of 60.7 fps.
With the minimum a little higher at 29.3 fps, the disabled
setting managed to score a higher average framerate of 49.1 fps -
0.3 fps or 0.6% higher.

At the resolution of 800x600, the disabled setting now had a wider
variance. The framerates it recorded had a minimum of 29.3 fps
and a maximum of 82.3 fps. Thus, there was a 53 fps
variance. The enabled setting, on the other hand, was a little more
stable with a variance of 51.3 fps.
Although the disabled setting had both the higher minimum and maximum
framerates, it lost in the average framerate by 0.1 fps.

When the resolution increased to 1024x768, caching the video RAM
surprisingly decreased minimum framerate by 18%! But caching also
enabled the enabled setting to beat the disabled setting by 0.4 fps
in the maximum framerate. The variance was higher for the enabled
setting at 48.4 fps while the disabled setting's variance was
only 44 fps.
On the average though, both settings scored rather similarly though
the disabled setting was slightly ahead. As we can see, disabling the
feature allowed for a less variable (more stable) framerate that also has
a higher minimum framerate, allowing for less jerkiness. However, as the
resolution increased, the performance advantage of disabling this
feature decreased.

In this single-texturing game, enabling the caching of video RAM
decreased the average framerate by 0.7 fps or about 0.5%.
In all three test runs, the disabled setting scored both the highest
maximum and minimum scores. So, I would say that the disabled setting is
the clear winner here.
