If anyone is wondering how this level works, here's a long explanation:

The level abuses something called the X position limit, a barrier that makes your position stop updating after reaching a certain distance into a level (basically freezes you in place). This limit occurs closer to the origin, the higher your FPS. For example, it's around 33 hours into a level for normal speed and 60FPS, but here, because of 5 million FPS, it occurs 256 units = 8.5 blocks into the level (30 units is 1 block)

The level uses this high FPS to its advantage by forcing you to freeze before a wall. While frozen, you have to continue spamming in one of the tightest UFO gaps (made by Illuminati65, works on 5mil FPS). Inside the gap there are exactly 322560 multi activate black orbs (in this video it's only one as it lags way too much). Multi activate orbs can be activated only once in a single frame, so by doing a double click you can click the orb once, and then jump right after, and the next frame the orb can be activated again. In here though, instead of double clicking you have to click all the 322560 orbs in one frame so none of them can be clicked again, and then jump with both players. You go up for 2 frames and then down for 1 frame by using the orb. You have to spam like this for a very long time.

Once you're stuck in that gap, a spawn trigger loop will activate and add 1 to a counter every 4 seconds (any higher value will break on FPS that high). The counter consists of 1098 pickup and instant count triggers stacked on top of each other (it uses all available groups). When the 1st counter reaches 2147483647 (the 32-bit integer limit), it overflows and loops all the way back to -2147483648, and eventually goes back to 0 (or 4294967296). Whenever it reaches 0, it adds 1 to a 2nd counter, which again overflows and goes back to 0. This adds 1 to a 3rd counter etc. It repeats until the 1098th counter goes back to 0. In total this process finishes after 4294967296^1098*4 seconds.

X pos limit depends not only on your FPS, but also on your speed. On slow speed it's at 256 units (8.5 blocks), but on 4 speed it's actually 512 units (17 blocks).
So when the last counter reaches 4294967296 and everything gets toggled off, you can just jump up and hit the speed change to extend the x pos limit beyond the wall, so you're able to move again and complete the level.

The level needs around 537603333333 CPS, and its total length is around https://pastebin.com/gXdPhtLe seconds (a number with over 10k digits) In this video it's shortened for showcasing purposes.
