I have an Asus F15 gaming laptop that runs MSFS pretty well. The problem with a laptop is that the small screen size means that glass cockpits are more difficult to see. For me (in my 70s) I find glass cockpits unusable, so I’m restricted to steam gauges (i.e. analog). Which for me is no problem as I like GA planes & I fly the Cessna C301R and the JF Piper Arrow, both with steam gauges.
I run on an MSI GE75 Raider, RTX 2070 and it is amazing for being 2 yrs old. Not running on ultra settings but a mix of ultra, high, and a 3 lows that don’t really make a difference visually.
This is what i have been flying just after release of msfs.
Does still a descent job with everything on high, and a couple on ultra. Just a bit of fan noice, but i always fly with headphones on, so no problems with that.
I can even stream my flights without any issues.

Another problem with running on a laptop is that laptop GPUs often have a limited amount of memory - my RTX3060 has ‘only’ 6GB. So if you fly near an area that makes demands on your GPU - like Milford Sound NZ - you may get some stuttering. Depends on the plane too, as that will be making demands on the GPU. I’ve also been very disappointed with photogrammetry but that’s at least partly because my GPU isn’t up to it. But overall running on a laptop works for me.
I agree with you on the limited Vram. I managed to get a little more by over clocking the Vram, don’t expect big difference but for me it helps.
If you are new to overclocking don’t worry, it’s safe to do.
