Hi. This is a mod that gives GTA 5 FidelityFx Super Resolution. Works with both AMD and Nvidia.
I have nothing to do with it, i only use it my self and thought i should share it because it is amazing.

The author of the mod is NarutoUA on github.com
Here is the link to gitHub. READ IT ALL. https://github.com/NarutoUA/gta5_fsr

I take no responsibility what so ever. I only provide the mod. I urge you all to read on GitHub before doing anything.
If i do anything wrong with this post then feel free to edit or delete.

So what does it do then???
Basically it gives you more fps with a trade off in image quality. How much of a trade off depends of your setting.
I use 0.883x - Ultra Quality Mode and see no trade off at all but gain about 20 fps. Not bad at all.
You might even get a more crisp image.

GTA Online

In general, mod works in GTA Online. If you are worried about being banned... Well, I don't know how GTA Online anticheat works so I can't guarantee that. I tried my best to make it anticheat-friendly based on my knowledge how other anticheats work. This mod doesn't require DLL injection, it doesn't modify game files, it doesn't change ingame memory, setup hooks etc. People ask me to add this mod to ReShade because it is allowed in GTA:Online. First of all, it's impossible. ReShade doesn't work with frame scaling and custom resolutions AFAIK. Secondly, ReShade became allowed because it started disabling Depth Stencil Buffer access, which is widely used in WallHack cheats, if any internet activity is detected (i.e. you are playing online). This mod doesn't touch depth buffer at all. Anyway, use this mod in GTA Online at your own risk.
