Digital Foundry basically disproves all the claims of other Youtube videos that thought Patch 1.11 improved the Wii U version.
Summary:
Overall, for the Switch version only, it still does not maintain 30 fps but it is a big improvement over the framerate drops of 1.10.
Framerate still dips as low as 20 fps but the game recovers faster than before.
Playing the Switch version in portable mode is the smoothest experience according to their tests and conclusion.
In portable mode, the framerate drops only in a few areas.
Switch version:
Dynamic resolution when docked: 900p drops to
840p when stressed.
Dynamic resolution when in portable mode: 720p drops to 648p when under load.
In patch 1.11 Docked mode: Kakariko village still has framerate drops to 24, 25 fps but recovers faster.
In patch 1.10 Docked mode: Kakariko village dropped to as low as 20 fps for a sustained period of time.
Korok forest still has framerate drops in Korok village but is tangibly improved over the previous version (as much as 10 fps improved over previous tests).
Wii U version (720p native resolution still): Still drops and locks to 20 fps for extended periods of time when stressed.
Patch 1.11 on the Wii U runs almost identically to patch 1.10 but with seemingly some minor improvements once in a while but basically performs
exactly the same within their margin of error.
