I have an ASUS TUF F15 that was working fine and giving me high fps until today where it capped all games on 60 fps, weird thing is that when i unplug my charger the fps goes back to normal. Please help.

Windows, by default, acts differently when on battery compared to plugged in.
On battery, performance is lowered and integrated graphics is used.
Plugged in, you use discrete graphics and max cpu performance.
Unfortunately, that generates heat that some light coolers are not well equipped to handle.
As a result, you may be thermal throttling.

Run an app such as HWMonitor or HWinfo, you will get the current, minimum, and maximum cpu temperatures.
For intel processors, if you see a max of 100c. it means you have throttled.
The cpu will lower it's multiplier and power draw to protect itself
until the situation reverses.

At a lower multiplier, your cpu usage may well be at 100%
What can you do?

First, see that your cooler airways are clear and that the cooler fan is spinning.

It is counter-intuitive, but, try changing the windows power profile advanced functions to a max of 90% instead of the default of 100%
You may not notice the reduced cpu performance.

The CPU temperature averages between 60c-70c

Try turning armoury crate off. Check your Nvidia control panel 3d settings to check the gpu power setting.
Just did it and still it didn't get solved. Its really frustrating me because the first week everything was fine then all of a sudden it caps games like valorant and league of legends on 60 fps. I tried CS:GO and the fps there isnt capped and works fine, can even reach up to 400 FPS on high setting . Super frustrating.

When the FPS drop happens, check your battery level, it might not be at 100%.
When the battery is not at 100% the Armoury crate software sets an EDP throttle on the CPU lowering its TDP.
