Did anyone succeed in putting a medium-heavy 3dgame from unity on a raspberry pi3 and play it?
if yes, how?
should i install android on rp and build my game for that or can i build linux version and then put it on a raspbian/linux pi?
Unfortunately, Unity does not currently support building for non-x86/x86_64 (i.e. ARM) Linux architectures. The best option would probably be to install Android. However, the Raspberry Pi, even the third generation model, is below even many phones in terms of compute power and graphics capacity, so you shouldn’t expect to be able to have many effects or high polycounts if you want a playable framerate. Additionally, I’m not sure if Android has the fastest or most recent rPi GPU drivers, so that might impact performance as well.
