Original post indicates it fixes a performance issue in Supreme
Commander, where it drops to < 10FPS after a while, presumably due to
graphics memory being exhausted and system memory being used instead.

Also in the original post is:

I'm not sure, because I don't have Supreme Commander, but I assume
this is a current work-around for the performance issue (setting
VideoMemorySize to about 50MB less than what your card actually has).
