I used the lut.png from RTGI Next so be sure to grab that, place the lut.png in reshade-shaders/Textures
FishEyeCA.fx can be gotten from the Carmack's Doom ReShade preset. It goes in reshade-shaders/Shaders
This preset seeks to improve the visuals of the game but keep the overall feel.
For best results put this in launch commands:
+menu_advanced_AllowAllSettings 1
Here's my steam launch commands.
+com_skipIntroVideo 1 +devMode_enable 1 +menu_advanced_AllowAllSettings 1 +jobs_numthreads 16 +r_useHardwareTextures 1 +r_TAATransparentsK 1 +m_smooth 0
Now in the Advanced options in the game set Shadows and Virtual Texturing Page Size both to Nightmare

Installation:
Download and install Reshade and make sure you select OpenGL or Vulkan
If using OpenGL then select the DOOMx64.exe, if using Vulkan then select DOOMx64vk.exe
At the top right, uncheck all and then check all.
Drag and drop .ini's from this .zip into where DOOMx64.exe is located
When launching the game press Home and set preset to either DeathWrench or Hell at the top
Additionally if you do not like the Film Grain or Chromatic Aberration then you can turn those off, and change anything else to your hearts content.

In Game Graphics settings
Make sure to disable Directional Occlusion in the in game Advanced settings. Even if you don't use this shader, this setting, when turned on, generally looks ugly and seems to not work properly.

The in game Anti Aliasing produces a doubling effect if you have it set to anything other than these 3:

Sharpening and Film Grain amount (you can turn off film grain in this preset and use the in game film grain if you want, or disable it altogether)

NEW GAMMA 0.8

OLD GAMMA is 1.6 - 1.2
