For some reason I’m getting very different results if I use DirectX when using cel-shading technique described in the manual:
Using OGL:
Using DirectX:
I’m also getting a very low fpson OGL when I use this effect (30 fps on my crappy laptop). If I remove the following lines:
self.panda.setAttrib(LightRampAttrib.makeSingleThreshold(0.5, 0.4))
self.panda.setShaderAuto()It goes back to the fps cap (60fps). On DirectX I get 55 fps. For such a simple scene with only one light source this is really strange (even in DirectX I think I should get 60 fps).
Am I doing something wrong? Or panda directX shaders is not working?
