For any fellow SSHIP player which may not be using Reshade yet and could be interested, I tried to keep it basic, It's mainly a color correction and some light.
You may also enable HDR, FilmGrain, HexLensFlare, ADOF and SMAA (They are set but disabled), but the current settings are a little off, so perhaps you'd have to tweak them a bit, but I remember I left them in a useful starting position.
Also, some loading screens get oversaturated because the preset is tweaked over battles/campaign, but if enough people download it I may correct that in the future.

Also, this one speeds up animations (therefore unit responsiveness also, but it's still not instantaneous) and movement speed, battles feel more alive and charges more epic, if you haven't already tried it yourself, I offer mine. You can further tweak it to taste as well of course :

Moreover, I find the game even harder with these values, beware of enemy knights! you'll probably have to learn to react faster. It can speed up your battles, but if you don't want that you can always increase the melee-hit rate separately.
