------- Additional Comments From vitaliy@kievinfo.com 2007-27-04 20:47 ------- What video card do you have? What drivers? You can't just disable vertex shaders and expect anything to work. You forcing HL2 into what's called dxlevel 60 mode - which is buggy and doesn't work.
What if you force it into dxlevel 70? When HL2 stars, open console and type "mat_dxlevel 70" and hit enter.
