Bad FPS in landscape

August 13, 2019 - 7:30am #1

Hi!

I've had a problem since late 2018 with bad FPS in landscape mode on my devices (Honor 8 and Honor 9). Currently Unity 2019.2.0f1 and Vuforia 8.3.8

If I set the Orientetion to Portrait in Project Settings/Player/Resolution and Presentation it works perfectly. But if I put it to Auto Rotation and flip it to landscape it starts ok but degrades over time, finally its just stuttering at about 5-8fps. 

I tested both to change it to Portrait only/Auto rotation in Project Settings/Player/Resolution and Presentation and changing it by script (I want to have portrait only in main menu and auto rotation in AR mode)

        if (sceneName == "Main Menu")

        {

            Screen.orientation = ScreenOrientation.Portrait;

        }

        else if (sceneName == "AR Scene")

        {

            Screen.orientation = ScreenOrientation.AutoRotation;

        }

I have a UI on the Camera with a lot of different elements on it, maybe it could be something there that's causing the problem?

Any ideas?

Hello,

Which Vuforia Engine features are you running when you see the FPS degrade?

This is the first time I've ever heard a case where rendering orientation is impacting FPS so it's quite curious.

Thanks,

Vuforia Engine Support
