On the other hand, Skyrim will run at its intended frame rate.If the game is 30 fps then my math tells me that no 30 fps PS4 game can be ported to Switch.
For 60 fps titles:
60 - 30 = 30 fps
For 30 fps titles:
30 - 30 = 0 fps
0 fps means 30 fps PS4 games can only run as slideshows on Switch.
You can't argue with math.
