For all those with Nvidia cards you have NIS (Nvidia Image scaling) which is the equivalent to FSR and it works through drivers (from November drivers and above) which means it can be implemented into basically ANY GAME. If the game allows you to change resolutions in the video settings NIS will work in that game.
The process of turning it on is straight forward:
1. You turn it on in the drivers under 3D setting or in Geforce experience, after you did that the screen will go black for few seconds and turn back on and after that the drivers will automatically generate 5 "scaling resolutions" to your system.
2. You open up your game and in the video settings you choose one of the "scaling resolutions". You have the option between 85%, 77%, 67%, 59% and 50% of your native resolution. After you choose one of those resolutions NIS will be automatically applied.
3. You press alt + f3 and the pop out window in Geforce experience will open where you can adjust the "sharpening slider" on the fly. The value is from 0-100 and you will have to play around with the values to find the best one for the game you're playing.
NOTES:
1. Keep Geforce experience turned on so you have the option to change the sharpening slider on the fly and see the visual differences in real time. Otherwise you will have to adjust the sharpness through drivers.
2. The sharpening value set in the drivers under Global settings will apply to every game once you enable NIS through drivers and you will have to adjust the sharpness every time you open some game. That's why it's much better to adjust the sharpness (once you find the value that fits you) for every game individualy under Manage 3D settings > program settings and keep the Global settings sharpness value 0. This way the particular sharpening value you set will be applied individualy to your games and the games you want to play without NIS will have the sharpnes level set to 0.
I have to admit that I was wrong about FSR (and now NIS) when it comes to games like Apex Legends. In such fast games it's hard to notice the difference between native and upscaled resolution, but the FPS difference you do notice. I play on 1440p and in some instances I do notice some differences, sometimes with the terrain and mostly when fying with the baloon or dropping from the dropshiop if you set up the sharpeniong too high. Personaly I wouldn't use it on 1080p, but those who seek more FPS can always try it out.
