How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
1: Launch the game, options, graphics. On top you can change API, to apply need restart the whole game. Start game, go to the options and choose different ambient occlusion technique in graphic settings, applies instantly.
2: Launch MSI Afterburner 4.4.0 Beta 12, set in settings RTSS - Raster 3D and Framebuffer. Launch the game (OpenGL), in menu it will be okay, but when you load level, OSD will corrupted. To fix it you can switch between Frame Buffer and Viewport in OSD, restart the game don't need.
3: Just run game with OSD, also you can quit in main menu and load your save again and it will crash performance even more.
Demonstration AO bug

Settings, i used window mode, ignore API and AO of course.
Demonstration RTSS OSD and performance problem
Switched between Frame Buffer and Viewport in OSD
Quit in main menu and loaded save again
I believe OSD performance problem it's a driver bug.
For OSD performance problem also check game "Dead Cells" its OpenGL game too.
Grab MSI Afterburner here.
Just interesting read, dev in comments talks about SSAO.
UPD: driver 4729
DX AO SSAO
OGL AO SSAO
