Reporting too little video memory is unlikely to impact performance negatively
since the location of the texture is entirely up to opengl. We don't claim
support for texturing from system memory(since windows drivers can't do that
either), and even if we did opengl would still do optimizations behind our

What it usually does is make the app tell you that you have to get a better
video card because it *thinks* it can't run. Or the app might cut back graphics

The only case where a wrong vidmem value negatively affected performance was
