Install the "DirtyCRT" preset file into your main GTA 5 directory or reshade folder if you have one, then activate the preset via the reshade settings. If you don't know how to do that watch a fucking youtube video it's not that hard either way....

If it looks like shit you installed it correctly.
 

Will work for NVE or Vanila and other basic graphic mods. 


Enjoy, now piss off.
