Fortnite experience HORRIBLE on Honor 90!!!

The honor 90 has a very capable hardware, it's not flagship, but it's capable to push 60fps in Fortnite, as the in game limit is 60fps.

Tho, for some reason, on this phone, the game randomly lowers fps, no matter the phone's temperature. And the worst part is that's intermittent. For 20 seconds, it's a smooth 60. Then, it goes to 30fps, and it's a choppy, a laggy 30fps. Then it goes to 40-50, and then, back to normal, to 60. This is not thermal throttling, because the thermal throttling actually fixes the issue, stabilizing the fps at a pretty decent 45!! :D

I have tried disabling couple services from honor, messing with them. Those include the Game manager or whatever it's called, system manager (which doesn't want to be disabled via ADB, no matter what). Nothing worked.

What I wanna say is, this phone is very good, the CPU in snapdragon 7 gen 1 accelerated is close to snapdragon 888 (trust me benchmarks don't tell the whole story), as I also have an OPPO find X3 pro, which pushes 60fps without problems, because there is no strange throttling like this. I don't even know it's it's a bug, or intentional to make a DIFFERENCE between midrange and flaghsip device???

Btw I'm on magic os 8 and I'm NOT updating, things got laggier when updating from 7 to 8, and I'm scared, because there's no going back.
