Hi there,
finally someone who asked this question. I search for it through the internet for many month now but only without result.
Sorry, I can't answer your question.
My intention for replying was to stress the importance of the question back to AMD.
In the whole graphic program (no matter whether it's Catalyst, Crimson, Adrenaline or one from Nvidia/Intel) there are so many tweaks like GPU-scaling (the most important in my opinion), screenshot function, hotkeys, automatic updater, last played games, color adjustement, etc. but the main aspect - how the configuration could be done silently without menue was never told to us, at least not for public.
If only AMD could be so nice and create a guide for that...
In my case I search explicit for a chance to change the GPU-Scaling option with CLI.exe in Catalyst (not in Crimson or Adrenaline) but without luck so far. I'm aware of how the aim could reached in the newer versions (with profile import/export) and that Catalyst is not longer supported official, but I would really like to know anyway.
