About Compute Luminance Pyramid #134
Description
I read the FSR 2.3 technical documentation, which states: "SPD is configured to write only to the 2nd (half resolution) and last (1x1) mipmap level." However, when capturing a frame of the demo in RenderDoc, I found that the actual luminance information is written to mip4 and mip5 of FSR2_ExposureMips, rather than mip1. I wonder if my understanding is incorrect.
And when FFX_FSR2_ENABLE_AUTO_EXPOSURE is enabled, it seems that FSR2_ExposureMips is not used in subsequent compute shaders.
