The possible reason why gamehub/gamefusion is not talked more about is because its a bit shady chinese closed source app.
I am staying with Joyplay and Winlator for now.
Firstly, closed-source and strange, yes, but one of the main things that wasn’t mentioned about this emulator in the news is that GameSir kind of bought this script/emulator from other people. Now, they have the rights and can modify it (community theory). However, 90% of this seems to be true, since earlier this year, a new emulator called Project Cassia was supposed to be released, but out of nowhere, the project was canceled, and the developers disappeared from the scene. The emulator community believes that GameSir hired the project's developers, which is why they vanished. I totally believe this theory.
About it being obscure, I have root access on my device and full control over it, from battery(I can exceed the permitted temperature limit) and I can dedicate 100% of the RAM to something, and monitoring to sensitive parts like GPU clock adjustments. I also use monitoring modules, and I never noticed anything strange about GameFusion.
By the way, what settings did you use for and the hat phoe you are using.
If you mean the settings of my device I have a moto g60, 6gb ram, snapdragon 732g, rooted, root only influenced termux when I used mobox, box64 and so on, now I only use modules with almost no effect on gamefusion and winlator. now if you mean gamefusion settings, basically I use 800x600 resolution (best performance in my opinion) dxvk 2.5.1 async, translation params, common or fast depends on the game engine, turnip v24.2 r22 only snapdragons (each snapdragon processor can be better with other versions.
