Hello,

I'd like to ask if there're some ways to make Firefox config using specifically the D3D9 path rendering instead of the D3D11 MS basic display driver the ANGLE wrapper seems to find and prefer basically not using any acceleration at all considering it's a compatibility driver in Win 8.1. I'm using an old GMA netbook gpu which has Directx9.3 PS3.0 support. I've tried any "force" options but no way it still goes for the WebRenderer (software) mode. I've tried forcing OpenGL mode but it seems to not use it cause old drivers and anyway I'd like to use D3D9 to also use eventually DXVA acceleration when needed.

In the heavier chromium based browser there's the ANGLE choice to use D3D9<>OpenGL ES translation but in Firefox it seems like only going for the D3D11 that of course find only the MS basic adapter driver which would have no sense using being a sw driver itself (beside not a bad software renderer but still slower than the D3D accelerator of this old PowerVR gpu).
Any suggestions?

EDIT: some log after trying all force options I've read..

(#0) GP+[GFX1]: Potential driver version mismatch ignored due to missing DLLs igd10umd32 v= and igd10iumd32 v=
(#1) GP+[GFX1-]: RcANGLE(no compositor device for EGLDisplay)

The gpu is a GMA3600. I'm not suprised OpenGL might not work but D3D9 should at least start like in Chromium browsers where is not perfect and probably slower than the software rendering but still can accelerate WebGL rendering while the sw renderer can't.

Thanks
