Old Valve/Source games lag on new laptop, but ran perfectly on my old one, anyone know why?

Hey everyone, running into a weird issue and hoping someone can explain what's going on.

My laptop specs:

CPU: AMD Ryzen 5 7535U

iGPU: AMD Radeon 660M

RAM: 16GB DDR5

Newer, more demanding games run surprisingly well on this setup, but older Valve titles (Half Life 2, Portal 2, Half Life Source, etc.) stutter and lag for me. Feels backwards, shouldn't the older/less demanding games run better?

Anyone dealt with something similar on an integrated Radeon 660M setup? Is this a known issue with Valve's engine (Source/Source 2) and AMD iGPUs, a driver thing, or something else entirely? Would appreciate any pointers before I go down a rabbit hole of tweaking settings.
