Shading Problem?

Hello. I have very strange problem:

Images says everything.

My PC Specs (don’t laugh):

  • Processor: Intel Pentium 4 2,4 GHz;
  • RAM: 1GB;
  • Graphics card: NVIDIA GeForce 7300GT;
  • Operating System: Windows XP 32bit Service Pack 3.

I tried re-installing GMod, checking cache files and anything, I should do.
But problem still is.

Please, help.

try putting in -dxlevel 81 into your advanced launch options

OK, it works now.
Thanks for the help.

Bump. Unfortunately, it’ doesn’t work properly.

EP2 effects doesn’t work…

Every SOURCE game are running on the DX9 mode, only GMod have an errors.
Any help?

If I want to change it to DX9, I must add -dxlevel 91 to start parameters?
