I'm tempted to feel sorry for him that he has to field such questions but hopefully he see's it as a compliment that people are so insanely invested in convincing themselves and others that only the PS5 could possibly run this demo at these settings and this performance.
Never been intrested in laptops before, i always assumed that mobile gpu variants didn't have the same specs as the desktop ones. Example, a GTX980 dgpu was much better specced then a laptop 980. It seems that since pascal things have changed, aside from clocks, they share the same specs for the most.
Actually might get a laptop in that class (the UE demo was running on), next generation console performance in a all-in-one machine i can easily take anywhere etc. Could easily hook it up to a tv etc. Offcourse, if the prices are somewhat human.
It's not shocking that a 2070 class pc can run this at the same settings etc, but that it does so in a laptop is. This whole ordeal seems laptop PR marketing lol.
Also, i have no doubt optimizing exists on all platforms, they probably can get it to 60 on both that laptop, xsx and even ps5.
