'live' settings updates cause DX crashes

I'd like to run full-screen and limited to 60fps (PC, steam) but to do that I have to go from 'no frame rate cap' to the first option which is 30fps, which immediately crashes with a directx error indicating the mode is not supported, which is not surprising. The same thing can happen when selecting an upscaling algorithm, because settings are applied the moment you change a value the game can easily get into a state where it locks up with no display (including no ability to get out back into windows) leaving the only option to pull the power cable and deal with whatever mess that leaves you elsewhere.

This would be easy to fix with an 'apply settings' button rather than immediately trying to apply any changes, or handle failures more gracefully (or, you know, at all). Game runs beautifully otherwise, but I know what settings I need - let me select them without the game trying to select everything else on the list first (and why can't I just select from a dropdown?)
