I need help removing video/visual memory

[siredhuman333]

I have a game called NiBiRu.
I have the requirements.
I checked my dxdiag and i have enough space.
but the graphics are really slow.
so maybe it needs more visual memory.
Anyone know how to get rid of it?
or how to get more [without buying a new computer]?

You have a Nvidia TNT2 Pro AGP 32 MB video card installed, and your computer will only support 1GB max of RAM using 2 512MB SDRAM 200MHz modules. You can upgrade your video card, and increase your system RAM to 1GB. How much hard drive space to do have left?
