why is my computer running games so booty?

hey guys, i have a lenovo "gaming laptop" I bought like 2-3 years ago that cant run anything stable and its really bothering me. hopefully someone here can give me some guidance on how to fix that. now to be clear, im not asking alot of this thing. I only play Cuphead and Rivals of Aether on it, and they both have requirements a fricking 2001 dell pos could run. yet im getting dropped frames in cuphead and rivals will lag out on some characters move animations every time and will just straight up freeze for like 2 seconds mid game, not even online, just story or practice. the eff is going on with my comp? it should be able to run 3 copies of both of these games simultaniously but i cant even get a smooth experience in 16 bit 2d fighters offline? i just updated my geforce drivers and it changed nothing and i have auto updates for all the others and windows claims everything is up to date. it cant be viruses i just dumped the entire system and reinstalled windows 10 last month and literally the only thing i have on the computer is steam, those 2 games and firefox. and i dont even browse the web aside from checking system requirements so no porn or torrent aids or nothing lol. why cant i get these things to run? any help would be greatly appreciated. id love to be able to play my 15 dollar indie games on this 1200 dollar piece of garbage.
