So you changed your mind and decided to keep your 128 MB graphics card. According to you what will be the effect of graphics card's ram on to this game? Especially if we assume to keep our 128 MB ones, cause really I was also decided to increase it up to 256 MB at least with a new VPU.

And also could you please write me down what it should be the settings of the game for Saphire 128 MB ATI Radeon 9800 pro ?

Shader should be 1, what else?
