How to increase .hdr resolution above 4k


I have been trying to increase the resolution of imported .hdr file. I have followed this thread:

but none of this works, I have copied BaseDeviceProfiles.ini into my project, renamed it to DefaultDeviceProfiles, also tried without Default, but anytime I opened the editor I saw the same thing:

how can I increase this resolution?

Also - I do not really care for performance, for testing purpose I want the highest quality possible. Each time I open UE I set t.maxFPS to 30. I did add this line to ConsoleVariables.ini but it does not apply. How can I cap my fps without doing it manually each time?
