I managed to borrow my work's copy (well.. their entire Steam Account ), and I tested SGSSAA ingame using the same old compatibility flag. With DX11 disabled, so everything on DX9 Ultra. SGSSAA works fine for me. Note that even with 8xSGSSAA (completely unplayable for me) that the red circle in the Nanosuit room is still aliased. However it's definitely less aliased.
