My Lenovo laptop (Ryzen 7 7840HS, Radeon 780M, 16GB RAM) suddenly became extremely laggy out of nowhere about 2 weeks ago even though before this I could run Resident Evil 4 Remake, Valorant, Genshin and PUBG smoothly without any problem for months around 60-100fps on low to medium settings and now I’m getting less than 20 fps in the same settings. I’ve already tried restarting, Performance mode, keeping it plugged in, virus scans, AMD driver updates and clean reinstall, but nothing has fixed it, so what could be causing this and how can I fix it?
