Pyro as Bill said:
Whatever the PS4P/Scorpio can play at 4K resolution, Switch will also be able to play at a lower but still respectable 720p resolution. |
No. In a lot of cases, performance is probably about much more than just resolution. A single bottleneck in some area could cripple the performance. A device is just as strong as its weakest area. Judging by the rumors, RAM could well be the biggest issue.
Also, native 4k AAA games are going to be rare this gen, I'm guessing.
