  • Why do you want to deactivate 3D acceleration? There is a similar question for Windows 8 on superuser : http://superuser.com/questions/495303/how-do-i-disable-directdraw-and-direct3d-acceleration-on-windows-8. Maybe it works for your, too. – Gnietschow Jan 24 '13 at 09:31

If you mean for your own application, you can disable GPU hardware acceleration by opting for the WARP driver type (D3D_DRIVER_TYPE_WARP) when creating the Direct3D device (D3D11CreateDevice).

If you mean for an existing application, you can do the same with the DirectX Control Panel (dxcpl.exe) and selecting "Force WARP".

  1. Disable Aero(Mostly not necessary but do it for now) Disable aero

  2. Download directx 9.0c control panel from here http://www.majorgeeks.com/files/details/microsoft_directx_control_panel.html

  3. Extract and run "directx.cpl" as administrator.

  4. Goto Direct3D and DirectDraw tabs and uncheck "Allow hardware acceleration ".
