Mine is also a laptop of i-7 9750H, rtx 2060, 32G ram, ssd, etc. and I use a Quest 2 with link cable.
I can say my computer is still enough to run sim in vr mode with medium or low graphic settings.
For me, even lower resolution 3D flight is more immersive than 4K 2D…
Feeling is like I’m in a real bird without my glasses…Everything is little bit blurry but looks real.
