Some of the maps really suffer from shadows that are essentially black.
The desert mission where you have to cancel the heretic transmission is one of the best examples.
You cant see anything on this map. The parts in the sun or blindingly bright and the rest is essentially black.
Flashlights surprisingly also do little to combat that.
The new map where you fight in the streets and churches of the city is also a good newer example. Everything in the shadow there is practically invisible because its just black.
Fatshark did such a great job with the environmental design, its a shame i cant see anything of it.
I do play on everything maxed out without RTX.
