Games unplayable due to thermal throttling lag. Any fix?

Just trying to play Donkey Kong Country Returns on the Snapdragon 860 Xiaomi Pad and I notice fps drops on 1x and 4x. Try every setting, nothing changes. Even Gpu usage is only half.
Then I enabled fps counter and whenever it hits 30 C it throttles to super low fps.
30 C is nothing, feels like a scam, it runs like a low-end device.

Is there any fix? Any tutorial that works? With root or so? Just 35 C would be enough, It’s just 10 C here too. If not don’t buy Xiaomi it’s not playable at all! It’s like a bad joke.

Edit: Ok it seems there is something wrong with Citra MMJ, normal Citra stays at 60 Fps even with high temperatures but sadly there a still stutters. I guess this is normal?

The flickering is only due to recording, but you can see its unplayable. I’m surprised no one else is experiencing this? Does nobody run 860?
