Rendering in higher resolutions leads to broken DOF and bloom in Unreal Engine 3 Games (Tested with Mass Effect 2, Mirrors Edge, Unreal Tournament 3).
See attached example screenshot of Mass Effect 2 with broken blur shader in the background.

Same issue with your newly added option DirectExt\AlternativeScaling.

System: Ryzen 5600X, RX 9070, Win10

It is the same problem as with other games: image postprocess texture coordinates do not align properly when resolution is forced. I'll try to come up with some solution for that some day.
