On my Android phone I don’t have any performance issues, but on my tablet, a lenovo a10-70f, it’s horrible. I tried with a nexus tablet, and again, performance issue. I have the issue with both 5.1.3 and 5.2.2.
My scene has quite a few world space canvases, but other than that, I can’t think of what could be the issue. If you take a look at the profiler, you see a performance hit, being the “profiler.finalizeandsendframe”. But when I turn off development build, I have a just as horrible performance. When I open an extra menu, the performance drops even harder. So it seems a canvas problem, but the profiler doesn’t show canvas issues.
Any idea what could be the issue here?
