Redundant render states!
Author
Hello.
I am trying to speed up my application a little, and before I get a profiler on the case I am trying all the 'easy' fixes, such as checking the DirectX debug spew. I keep getting this message.
Direct3D9: (WARN) :Ignoring redundant SetRenderState - 60
Could somebody tell me which renderstate this '60' refers to, and also how I would go about finding this out for myself.
Thanks in advance.

1) Open the "d3d9types.h" header file and go to line 325, you'll see a "typedef enum _D3DRENDERSTATETYPE" around there. That contains the numerical value for each renderstate.
2) A quick look at the above list reveals: "D3DRS_TEXTUREFACTOR = 60"
3) D3D does contain its own internal redundant state checker for non-PURE devices. So when you set the same state twice in a row, that warning message is it's state checker telling you. For that reason, unless you're using a PURE device, a redundant state checker in your own code is only truly useful if it can do it on multiple chunks of state (you can use application specific knowledge here).

Dont mean to take over the thread but does this also apply to sampler states?
I`m getting the following:
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 13
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 14
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 25
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 15
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 19
Direct3D9: (WARN) :Ignoring redundant SetSamplerState Sampler: 0, State: 20
but the thing is in the "d3d9types.h" header file theres a typedef for the samplerstates but that only goes up to 13 (as far as I can tell)?
Thanks
