How to get graphics sharp?

Hi, so a few days ago I came across this clip of an Ana potg on the forum “Why i’m an Ana main”. I saw a persons sharper and less blurry graphics. and they made me wonder if I could do the same with my graphics. I just think it would be nicer to have more crisp and clean graphics. If anyone can tell me what specific settings I would need to make it look better I would highly appreciate it. Thanks in advance

To improve overall sharpness, you often need to increase your rendering scale to 100% or higher and make sure your resolution is at least at 1920x1080 pixels or matched to your screen size.

Is there anything to do with anti-aliasing?

I personally keep mine at LOW – FXAA for the in-game setting. Anti-Aliasing works to smooth blending of pixels together and can cause some fuzziness in some areas.

Okay that defiantly helped. Is there any way to make it more pixely without the blurriness?
