The goal of this small Reshade is to make the look more modern while also keeping the vanilla look with minimal performance loss by adjusting contrast, saturation and adding bloom.

Screenshots are taken with these optional mods installed:
Tast's DayNight Changes Reborn and Tast's DayNight Changes Reborn Raid Addon
(Raid Addon can affect FPS though*)

Reshade tested at high in-game settings at 1080P:
-GPU: GeForce GTX 1070 8GB
-CPU: Ryzen 3 3100
-RAM 16GB
Average performance loss: barely noticeable

Alternative version with motion blur from this mod is available in the download section
