I made this video today showing the load time differences between many versions.

Loading on console from a hard drive is very fast and definitely should be not allowed.

Wii U appears very slightly faster than Wii but it adds up to a 12 second difference throughout a 32 track run.

I also tested Dolphin running from a backup disc because it technically is allowed according to the rules (it's not an ISO). The gameplay is quite inconsistent, but if you eliminate frame stutters it would be slightly faster than Wii U.

Wow. Thanks for doing this. Excellent video.

Wait, so Dane (#4ww) actually has the world record!!!!?????

Holy hell!

I'm guessing there is a variable of inconsistency somewhere in this. I only ran this one test due to the grueling method of testing this. Though the inconsistency between the results of the first and second test in my video can be attributed to performance hitches in Dolphin (frame stuttering). The fadeout portion of Dolphin Disc actually has around 5 extra frames due to this stuttering, making it appear slower than Wii Disc and Wii U Disc in the end.

The 12 second number is just based on this test multiplied by 32, which doesn't really work in reality. Each track has different assets and therefore different loading times.
