A Reshade aided AA with a little VSR resolution increase to combat aliasing issues of the game.

If your Reshade version is older than 4.8 please make an update so it automatically downloads Contrast Adapptive Sharpen and TAA.

An example of how to use the formula in the video.
Let's say you have a 1920x1080p screen and set your game resolution to 2880x1620.

(1920x1080) / (2880x1620) = (actual total pixels) / (total pixels the game creates) = 0,444
That's your downscaling ratio

Let's divide it by 3;
0,444/3 = 0,148 That's the value you put on TAA User Adjust.

Substract it from 1;
1 - 0,148 = 0,852 This is your FXAA smoothing value. This value is also the "max" value for Contrast Adaptive Sharpen. Higher values than that may bring some shimemring back. I wouldn't recommend.

I just picked, calculated and set the values on this preset. I did not write the actual code. That honor (and talent) belongs to Crosire for creating Reshade and BlueSkyDefender for implementing Unreal Engine's newest TAA to Reshade.

TAA needs motion vectors to keep track of objects moving throughout the frames so it can blend them correcty. Unfortunately those motion vectors can only be revealed by Rockstar themselves, whom I believe would never care. So TAA without motion vectors acts as a "pixel based motion blur" with Reshade. Luckily, even that helps a lot.

The bigger the color difference of a pixel between two frames the harder it gets blended, thus "masking/blurring" most of the pixel crawling problems.

A high quality FXAA solves the jagginess. And finally, increasing the resolution beyond the screen's native resolution helps with terrible geometry rendering desicion of Rockstar. (further objects gets created in lower resolutions with "holes" inside them)

My screen resolution is 1920x1080. I play the game at ultrawide window. This gives me an actual resolution of 1920x800 pixels. The rendering resolution is higher than that (2880x1200 when not recording).

The entire video is then upscaled to 4K Ultrawide to avoid Youtube's compression.

For a 16:9 comparison;
2880x1620 (2.25x more pixel count than 1080p) + Reshade gives better "performance" and "visuals" than 4K + in game FXAA (4x more pixel).

Because, without some post processing effect, even 4K can not hide most of the pixel crawling and shimmering artifacts.
