I doubt memory is as big a problem as other aspects. Granted memory space helps games with large textures, but when I consider my laptop with 4GB, and my desktop with 8GB, both of them seem to play fine.
I run an i9 (12900k) with 32GB of DDR5, but only a 3070Ti. Yet, I play at 1440p, 100FPS at full Ultra.
The laptop is a bit lower, since its an 11400h, with 32GB DDR4, and a 3050Ti. However, it runs HD at 100FPS on High settings.
There have been mixed results with using older drivers, as well as latest driver with some different settings applied via the driver itself. You can find details here in my most recent post:
