I guess the Ace 2 be one of the best options? or anything similar like realms GT Neo5. At max settings it'll probably run hot, but if lower the graphics a little (I usually turn everything except render resolution 1 step below highest), SD8+G1 should be able to handle it? On a phone screen that difference in graphics is barely noticeable, and render resolution for medium on Android is low enough that it is quite noticeable. Plus Ace 2 has that Supervooc S charging chip too, so might be better if you need to charge the phone while playing the game too.
(the bottom right. for those who can't read Chinese, it basically say "Temp control mode: charging while gaming, get both speed and thermals").
If they didn't do anything weird to the tuning like they did with the 10T at least. Then in my experience ah, just get a cheap USB/battery powered fan and point it at the phone while playing. Probably will be more than enough to keep the phone cool enough to maintain 60FPS liao. After all, the RedMagic 7S Pro was able to handle the game well too. Even with OP11 I use a fan too to keep the phone cool since too much heat isn't good for electronics/battery.
But if want play at really high graphics ah, then not sure liao. Since even SD8G2 probably will need a fan blowing at the phone if you want good temps for long gaming sessions. maybe a used iPad mini 6 will be in that budget already. lol
