Game mode doesn't matter, but currently trying get performance right while messing around in single player - axis campaign, mission 2 (the night one).
I've run AIDA64 logging during gameplay, and pretty much every crossfire capable game I have will push both gpu's past 90% easily as long as I turn vsync off and let the frames blast to the max. RO2 on the other hand caps gpu util at about 40% average for me, both gpu's. This behavior is irrelevant of the graphics settings chosen (within the game UI at least). The log below is from default/vanilla settings after deleting the RO2 folder and letting the game recreate all the ini's.
I've made another interesting observation - if during gameplay I esc in to the menu and go and uncheck all the boxes in video settings, and then get back to the game, and then go back to the menu again and check all the boxes back, and return to the game once more - the framerate delta is roughly +10fps for me. Essentially, changing settings to off and then back to on as originally set yields a performance boost for a game already in session.
Anyway, hope this helps. I know if my gpu's cranked at least up to 80% my fps would be very playable and I would love the game.
