Hello,why would my computer say my video card needs to support shader 1.1 or higher
I can assure you, your computer doesn't really care.
But some software you are attempting to run on your rig might require Shader1.1 or higher... such as a game.
Older integrated (on-board) video without hardware acceleration will have this problem, also a lot of laptops that are a few years old now...
But even the dirtiest $39 buck DDR2 vidcard will have Shader2.0 these days.
