I get error code 20, “invalid channel descriptor” from cudaBindTexture2D, only in release builds (debug seems to be fine).
Any idea why? Isn’t it highly unlikely that the driver doesn’t support 8-bit unsigned textures? Those are essential in games. And again I only get this error in release builds :|
Personnaly i use 8-bit unsigned textures.
I could be a wrong initialisation or a missing initialisation.
What are you doing exacltly?
are you doing something like that:
texture<BYTE,2,cudaReadElementType> tex;
…
cudaBindTexture2D(0,tex,array,cudaCreateChannelDesc(8,0,0,0,
cudaChanelFormatKindUnsigned), width, height,pitch);
where array is what you want to bind with texture.
