Are you from the AMD development team? It looks to me like the new design is intentional, so there is no guarantee whatsoever that they will bring back the dynamic range option. In Crimson, it follows the pixel format option (0-255 for RGB Full, 16-235 for RGB Limited), and in a way it makes sense like that. The levels are fine in RGB Limited, but that's not the best mode for MadVR. It's only if you switch to RGB Full that you have levels issues with PowerDVD, especially if your display is set to HDMI standard. It would be great if they decided to bring some advanced options back, but the fact that RM doesn't work with Crimson regarding these is a bad sign, as it means that there is no registry have to provide this level of control. This isn't only something that's not accessible in the settings app anymore, it looks like it's gone in the driver itself.
