FPS ALWAYS CONSTANTLY

When you look around, usually, your vision have a excellent fps ;)

prefer performance rather than graphs

You can check the device and change your graphics configuration

//SystemInfo.deviceModel ->samsung SM - G925I//SystemInfo.graphicsDeviceName -> Mali-T760//SystemInfo.graphicsDeviceVendor -> ARM

if(SystemInfo.graphicsDeviceName.Contains("Mali")){ChangeSceneSetup();}

Different scenes

with different graphics

with different setups, right?

GPU / CPU Level Throttling

OVR_VrModeParms_SetCpuLevel(3); OVR_VrModeParms_SetGpuLevel(1); OVR_TW_SetMinimumVsyncs(OVRTimeWarpUtils.VsyncMode.VSYNC_60FPS);

Signing Builds for gear VR

Signing Builds for VR after APK is done

Add your sign file into Assets folder

Debugging on Gear VR

Debug WiFi

ADB WiFi Connectionadb tcpip 5555adb connect :5555

ex:

ADB WiFi Unity Connection

I dont have WiFi!

Gear VR Develop Mode

Application Manager -> All -> GearVR Service -> Manage Storage and tap VR Service Version 7 times

The device is getting hot!

Optimization

Optimization start in the FIRST day.

If youre not optimizing for the games bottleneck then youre wasting timePhil Lira, Staff Eng.

Loading Time

Texture compression settings

Texture compression settingsIf the device doesnt support your texture compression, Unity will decompress all textures before splash

Disable autoconnect Profile if you are debugging loading time

DrawCall/SetPass

Conclusion

ImmersionOptimization starts on the first dayAlways prototype and test a lotFeedback as much as you can

And you should test Finding Monsters Adventure VR and Rococo VR :)Conclusion
