I found new skips that can only be performed at 60 FPS on PC version. The whole point is to quickly and constantly press the jump button. It takes a little practice.
Gold Acorn cutscene skip < this skip were found by Zetrile
Skip an entire Forest 1
Skip the end of Forest 2 (We don't need to waste time on a rhinoceros and carry apples to a large mammal. Now we can just jump to all nests and get all 5 nuts) 1st nest: 3rd nest: 2nd nest: 5th nest:
Tiny skip in Forest 3 Another little skip in Forest 3 that saves us a few seconds and also works at 30 FPS.
- Out of bounds in Forest 3 (We just get into the water and can go back to the level. It doesn't do anything, but I'm 100% not sure) More detailed video
Skip the spikes in Inside A Fish
Skip an entire Mud Bog 1 & 2 < these two skips were found by Zetrile https://www.speedrun.com/user/Zetrile
Skip an entire Mud Bog 3
Skip in Sloth Village 2 (At 60 FPS we no longer have to swim underwater, climb a wall, and risk being stopped by a spider. Now we just jump on log, then run towards group of stones and, as shown in video below, jump several times towards platform with the nut)
Time-saving skip in Sloth Village 4 (You may notice that to jump in there, you need to aim at the corner, just a little to left of gap with lava flow. Pay attention to small cloud that occurs when Scrat touches some surface. It is this area that gives us opportunity to push off and jump to nut. This skip, unlike others, requires a little more practice. [Unfortunately, YouTube made video darker, but nevertheless it's quite obvious in which place you need to make a skip]) A slightly more complete example
Mini skip in Sloth Village 5 (Skip climbing the wall, risk of being fried [fire stops us for a second], risk of being stopped by a spider [also a second])
Next, we don't need to go for stone, we just jump to the next platform through an inclined surface.
Time-saving skip in Sloth Village 5 (We skip a tunnel with fire, descent on a rope, two rocks and non-skippable cutscene. In the place where Scrat slips, you must press jump button as often as possible and without stopping. If you do everything on first try, you'll save a decent amount of time. However, this skips requires long and hard practice)
- Improvements in Sloth Village 5 that are slightly faster than in the video above.
Time-saving skip in Glacier 1 (Here we skip completely Glacier 2, which is with Diego)
Skip Glacier 3
These are all possible skips. Only some skips save time in minutes, which must be done on the first attempt. Remaining skips only save a few seconds.
At 60 FPS, Scrat can touch almost any inclined surface for a few milliseconds during a double jump. At 30 FPS, Scrat will simply roll down, i.e. above skips will be impossible. There is also possibility to get out of the levels, but this doesn't give much, because one wrong step and you just fall endlessly down.
Bonus: In the level with Sid at 60 FPS arrows move too fast! It's impossible to keep up with them, so in this mode they are meaningless. Moreover, you can score more than 7000 points without these mini-games for reaction.
