HELP: flickery gameplay....MOBILITY RADEON 7500

[bman18]

i need major help on the quality of gameplay....it flickers like crazy when i play with horrible graphics.

my graphics card is MOBILITY RADEON 7500. is this graphics card good enough for the game?

i read in a message earlier that the ram of the video card also matters...how do i find out the ram of my video card?

thanks.
