System Tweaking Tips and Advice

  • If you are running Windows XP SP2 with a multi-core CPU, it is advised you install this MS hotfix.
    Installing this hotfix ensures Supreme Commander uses all available CPU cores.
  • Turn off Shadows! Yes, they look pretty, but they 1/2 the framerate, even when on the Low setting.
  • Large games that cause Supreme Commander to use >1.5GB of RAM will crash due to a bug. To fix this problem, see here and here.
  • Make sure that Anisotropic and Antialiasing settings in the nVidia control panel are set to "Application-controlled".
    Not doing so can cause Supreme Commander to crash.
  • If you are using a normal ADSL/Cable router, you DO NOT need to forward any ports to play or host a multiplayer game.
    Forwarding ports can cause problems when playing GPGnet games (ie, yellow & red pings).
    Supreme Commander is smart and takes care of port forwarding (or NAT) on routers itself.
  • Long load times and jumpy gameplay slowing you down? Vet anti-virus(aka Computer associates) causes this. Maybe other AV's too. Exclude the S/C directory from real time scanning.

Supreme Commander Console Commands

Enter the console in game by pressing "`"

  • ren_Water disables the rendering of water, which increases FPS significantly on water maps
  • ren_Fx disables all particle effects (such as smoke, fire, laser beams, sparks and the power line from power generators to factories indicating the adjacency bonus), significant FPS increase
  • ren_Terrain removes all land textures. Units are a lot more visible. FPS Skyrockets
  • ren_Skycube disables the background image AND reportably the SkyCube for the map your in. FPS can increase significantly
  • ren_MeshStatic disables Trees, Metal Deposit Lumps and Hydro-carbon deposits. The image behind them is still visible (eg: the green picture behind metal deposits), slight FPS increase
  • ren_Decals disables the scarring effects of explosions and craters (different from ren_NormalDecals, as this command turns off all bump-mapping and terrain deformation) Large FPS Increase
  • ren_NormalDecals (similar to ren_Decals, but still renders the terrain deformation such as ACU crater and rocky hills) Large FPS Increase
  • cam_Free - disables health bars and build progress bars on units, significant FPS increase
  • ren_Splats disables scorch marks and craters, slight fps increase (depends on how many scorch marks are on screen)
  • ren_ShowSkeletons disables textures for models, and replaces them with the "skeletons" for units/buildings. Significant FPS increase
  • ren_Reflection is reported to increase FPS slightly (unconfirmed)
  • ren_Refraction is reported to increase FPS slightly (unconfirmed)

Supreme Commander EXE Command lines

  • -nomovies etc, anyone know of any yet?*
  • /nosound - Disables Sound
  • /map - Loads map, use PerfTest to do a benchmark. ie /map PerfTest
