Poor performance (low FPS) on a Pixel 4a 5G

February 10, 2021 - 8:06am #1

Hello everyone,

I'm currently creating some AR game levels with Unity 2020.1.14f1 and Vuforia 9.6.4.

Everything works perfectly when I'm testing directly in Unity, but on my Android phone, I have huge performance issues.

When the Image Target is not detected, I already feel a high latency on the camera and when my GameObjects are displayed (therefore the Image Target is detected), I'm literally at around 5fps with a lot of freezes, in short... it's not playable at all.

My phone is a Google Pixel 4a 5G, so it surprises me a lot to have terrible performance on a recent phone. So, what can I do to achieve a reasonable framerate?

I already tried to switch the camera mode to MODE_OPTIMIZE_SPEED, uncheck Include ARCore library and switch to Very Low in Quality tab of Unity Project Settings.

On my screenshot, you will have a overview of what my project contains.

I wanted to ask you to test with the video mode SPEED but see that you already tried it. I tested our Core Sample app on Huawei P20 PRO and did not encounter any performance issues. Unfortunately I do not have the device to further test the CS on the device.

Could you please try out our Core Sample app from the Unity Asset Store and let me know if the issue is reproducible?

Thank you.
