Low FPS (20-25) with 4K Video Feed in Unity with Vuforia on Mac M1 or Intel 13th gen with RTX 4090

[VA_12110304]

Greetings,

I’m experiencing performance issues when using a 4K video feed (3840x2160) in Unity with Vuforia. Despite optimizing settings in Unity, the frame rate remains at around 20-25 FPS, even when using high-end hardware. Below are the details:

• Mac Mini M1 (Apple Silicon, Metal API enabled) and Windows 11 with RTX 4090 and Intel 13th Gen CPU.
• Unity version: 2022.3.50f1 (Apple Silicon support on Mac, DX12 on Windows).
• 4K feed stutters in Unity, but works fine in OBS.
• I've tried disabling VSync, optimizing the scene, and adjusting other Unity settings like multithreaded rendering, but the performance issue persists.

Is there any specific configuration or optimization in Vuforia that would help improve 4K AR performance across these platforms? Your advice would be greatly appreciated.

Thank you!

Hi @VA_12110304 ,

your question seems to be a  Vuforia Unity question  and is not directly related to the  Vuforia Studio product.  Therefore I want to refer to the Vuforia Developmet portal - support -  https://developer.vuforia.com/support where issue for Vuforia Engine /also unity related are handled.

You can aks questions and discuss with other developers via the official vuforia tag on Stack Overflow
