I cannot add an app to the list to manually set it to high performance (Radeon instead of Intel HD). When I browse for an exe, nothing happens, the list is still empty. So, maybe I can edit some .cfg or .ini?
This is NOT my screenshot... actually I've found it on the Net. The list with iexplore.exe is what I meant. When I click 'Browse' and choose any exe (Portal2.exe, for instance) nothing happens. The list is empty, so I cannot set mode for Portal2.exe.
