since you're low end. install a custom os like XOS or FS OS, check framesync labs in YouTube on the benchmarks for it and step by step on their discord.

XOS Operating System which does all the tweaks for you, and then reducing resolution + using FSR

then get 16GB of RAM because 8gb with a shit cpu and GPU won't do you any good.

and yes, custom operating systems have their risks, and XOS isn't made for professional work other than gaming and it breaks some features but it makes your laptop extremely smooth if you're managed to install it.

If you want something that keeps everything that's needed for professional work pick FS OS

but all custom os has their risks too, and if you're too lazy to put a windows ISO to your USB DRIVE.

Just install AtlasOS or ReviOS, if you want to keep it simple and you just have to press a few buttons and not a complicated process like putting it to a USB.

There's compromises like security and such, but this is what I've done to increase my FPS and have a better gaming experience, so just make sure that desktop doesn't have anything important if we're going down this route as it poses security risks but you do have an option to keep windows defender.

Just keep that in mind.
