Gear VR S6 Android 5.1.1 vs 6.0.1 - performance drop - WaitForGPU/vsync issue
Hi! We are developing VR game for Gear VR (and Rift later on). Recently we spotted performance drop from stable 60 fps down to 30. Further search showed up it's due to abnormally high WaitForGPU and ...
We checked power saving mode but it was not the case, it was still disabled.
We're using Unity 5.4.0b9 now and it worked without any problems before Android version upgrade. We created both builds from this Unity version and only Android 6 coulnd't handle 60fps. We tested a build on Unity 5.3.4 as well and the problem happens there as well, profiler shows 30FPS but the big amount of work is presented under "other" instead of "VSync" category. We're using 1.3.0 plugin for both 5.4.0b9 and 5.3.4 versions of Unity.
I'm attaching some logcat prints, a copy for Unity 5.4.0b9 build named NewUnity and a copy from 5.3.4 version build - OldUnity .
