Thank you for the info. Could you check it again, please? Because I did that a few times and it might be something else :( There is something going really bad. I tried similar setup (experience/tourist + smaller) on two versions. I did uninstall (through adb) and install both versions and it works similar. A drop here and there (menu is unplayable). It is still far from good (many times GPU is at 4 and utilisation >90). But a day or two ago I was testing newer version (0.3.13) and a few playthroughs were unplayable, it was so bad. I am now investigating, what's going on. Haven't changed anything related to rendering (even the basic meshes) since first 0.3.11 (#190).
I will need to provide an option to reply same seed, so it is easier to test the actual performance.
