The default release mod that comes with the source SDK Visual Studios Projects is all right for many mods, but it can be better, and run faster with some small changes. In the project properties page of your client and server, change these settings to get faster DLL-files.


General

  • Whole Program Optimization 'yes'
Note.pngNote:Memory requirements can be very high when compiling with Whole Program Optimization on


C/C++ add these two switches to the 'command line'

  • /GL /G7


Link add these three switches to the 'command line'

  • /OPT:ICF /OPT:WIN98 /LTCG


It will take longer for it tot link the code, but it will run faster then with the default release mode.

You can also enable SSE (Streaming SIMD Extensions) optimizations due to the minium requirements of HL2 being a 1.2 GHz CPU, that defaults to a Pentium 4, or AMD Athlon that support this technology. This can be found under the Code Generation.
