Open jeffnn opened 4 years ago

jeffnn commented 4 years ago

Repro: Run the pix file mentioned in PIX bug 26308011. Attempt to recompile the shader in question with /Od. (Ask jeffnn/jeffno for details on how to do this)

@jeffnn - moved this to dormant (ie we're not planning to schedule anyone to work on it). If you happen to know that this is no longer relevant please feel free to close it.
