You're not the only one with the problem of a weak PC. I have the same problem. I remember when I found here https://www.techshout.com/great-games-for-your-non-gaming-laptop/
different games for weak PCs and played and enjoyed it. One of my favorite games was Grand Theft Auto: San Andreas, the fifth edition of the GTA series. I've been through it, like, 3-4 times.
