Try this, open msconfig, got to the boot tab then click the Advanced Options button. Then set maximum memory to 2048 and reboot. This didn't work for RF1 but for RF2 it works fine. Just remember to untick the maximum memory box and reboot after you finished playing. This has nothing to do with video memory, Microsoft has taken the methods of the illusionist and applied it to software, i.e the art of illusion is misdirection.
