Laptops with the newer nvidia generations that support framegen make this a harder argument. Yes, laptops are always severely power and thermal constrained, but you can run raytraced games at 1440p 240hz on them now. HL2 RTX at that fidelity is a trip. The concept of a high end gaming laptop is a pretty big market, but not when the mfgs and firmware devs can't manage to prevent stuttering that most of their target market would notice and find unacceptable.
