FPS counter bottom right is bugged
and radeon adrenaline doesn't seem to recognize your app as a game so it won't give me driver overlay. looks like is is just drawing over itself and not clearing it. this is probably related to the lack of black background on the wide screen area as the FPS counter is anchored to bottom left which is well outside of the play area in the center.
I had to add the game manually to the gameslist in radeon, and enable the overlay. it gets about 376-389FPS pretty consistently, with occasional dips to 260 fps on room changes. specs are 7950x3d / 9070xt / ssd
