if you search on google you can find reshade.

its free.

install into each game seperately pointing at the cfs exe.

when it asks to install something so it can run in dx8 ignore it (runs in dx9)

you run the game. upon sitting in the cockpit you can see text overlay top left.

it will say to press the home key, do that.

you can simply tick boxes to try effects. my favourite is hdr fake.

i guess if you also ticked bloom you may have what you are looking for.

note the game may freeze for quite a while when initially choosing an effect just wait.
