Setting 3DCONFIG Manual Tune Options In Command Line

I am looking for a way to set a couple options in the Manual Tune window from the Performance Tuning window (3DCONIG Prompt). More specifically I want to be able to:


  1. Check what the setting for Enable hardware acceleration is (so it can be restored back)
  2. Set Enable hardware acceleration off
  3. Reduce the number of tessellations to cache
  4. Reduce both the Surfaces, and Curves tessellation

How would I do this from command line? My ultimate goal here is to run these commands in .NET.

You can set some of the acceleration parameters using the commandline version of 3DConfig: -3DCONFIG

We are using it in our TURBO utility -


Other parameters can be set in the Registry - in HKCU....3DGS Configuration\\GSHEIDI10  (be careful when changing these values)
