@DonPablo I have tried everything so far including NVE. and I can honstly tell you Redux is the best of the best graphic mod I have ever seen compared to everything else.
It's not absolutely perfect, it has it's flaws too I admit. but it's compatible with every other mod you can use etc corona, rain, water and such. and it's free.
The main problem of Redux is it's installing bunch of other things that are not related to graphic improvement and many people including me don't like it. If it had an option that only installs graphic mods it would be truly perfect really.
The only mod that can excite me more than Redux is GTA V Remake although it's in early access too and just released today. That mod truly has a lot of potential and I am looking very excitingly forward for it's final.
