Dynamic Shadow - Problem with Shadows

hi all I need help with dynamic shadows

Intel® HD graphics 4000

why doesn’t work, tell me?

turn your shadows to high if that doesnt work the source engine is preventing what your hd4000 can’t handle for a GOOD reason.

maybe the reason is not due to my graphics card?
because i see,that worked previously
2 gb memory

ops sorry GT - 630M videocard

Make sure GMod runs on your primary video card, not the power saving one.
