Found while trying to play @Dragosha game on my TV box, is just a device with android 6.0, it works 99% like a tablet, with a remote control, and I can plug keyboard and mouse. I have played there many popular games without issues, including my own 2D game made with UE4.
Tried running bunnymark project but all buttons make the app close except the one that use particles.
While Blossom Blast Saga runs perfectly fine: video
This may look like a rare device but inside is just another tablet made in Asia. There are many of this kind of “TV boxes” on amazon. And if the problem is related to vsync, I also had problems with Defold on a laptop that I have VSync globally disabled on NVidia control panel, and all Defold projects runs high-speed. Not good.
