Material Problem

Blood particles and water are messed up and little things like the vortigaunts eye being wireframe. The blood particles are wireframe for some reason and whenever I go under water the whole screen turns gray. Then when lag occurs half of the screen is wireframe and flashes different colors.

I have tried reinstalling it three times and it still has this problem. I use steam and every time i tried to reinstall it, it would jump to 51%. Whatever is wrong with the game, it seems steam is keeping it.

So I need a fix for this I have no idea how. I have tried everything. Any help would be greatly appreciated.

Try defragging it. Or update video card.

I did both and neither fixed the problem.

So no one knows how to fix this?

Have you tried using -dxlevel 80

bump for knowing the answer :<

Your screen resolution is very low. Very low.

On-topic, try re-installing, cleaning GMod or defragging.
Or perhaps update your drivers.

We have the same problem. if your using -Dxlevel 90. its a lot better for ragdoll posing. but you cant spawn TF2 ragdolls. -Dxlevel 80 is just fine. but Its not lighting up the ragdolls. i prefer to -Dxlevel 90+. or 80.
