Freestyle is already live (although still on Beta). I tried it yesterday and absolutely loved it, it works pretty well in a game like this where colors are washed out. Here's a few things I could observe:

- No impact on performance. Stormshade and its presets makes my FPS dip by 40+ on maximum settings.
- Doesn't screw up your HUD transparency like ReShade does (this is the big dealbreaker for me)
- Much easier to tweak and customize
- Seemed to have less of an effect on screenshots compared to ReShade

Can't speak on the colorblind feature since I don't have this issue, but for all intents and purposes of making the game look more lively and pleasant to the eyes without hampering performance, I'd say it does wonders.
