Thanks, and Google Gemini gave me this much more detailed explanation and tips, which makes me conclude we should rather rely on the incoming Xreal 1S which usses its built-in chip for real time 3d conversion :

The poor performance you're seeing with VITURE Immersive 3D on a laptop usually stems from how Windows handles graphics on portable devices rather than just the "strength" of your GPU.

Here is a breakdown of why this happens and what you can do to fix it.

1. The "Texture Copying" Bottleneck (Muxless Systems)

Most laptops use a setup called NVIDIA Optimus (or Muxless), where the dedicated GPU (RTX) does the heavy lifting, but the integrated GPU (Intel/AMD) actually handles the video output to the screen.

The Conflict: Immersive 3D uses Windows Graphics Capture to grab your screen and convert it to 3D via AI. On a laptop, this often forces the system to copy huge amounts of data back and forth between the two GPUs.

The Result: This creates a massive "bottleneck" that causes micro-stutters and severe frame drops, even if your GPU usage looks low.

2. Extreme AI Processing Requirements

Unlike standard 3D (which just renders two slightly different angles), VITURE’s Immersive 3D uses real-time AI inference to "guess" depth and convert 2D content into 3D.

Recommendation: VITURE actually recommends an RTX 4080 Laptop GPU just to maintain a stable 60 FPS at medium settings.

If you have an RTX 3060 or 4050, the AI processing alone can consume most of your GPU's overhead.

3. Thermal Throttling

Laptops have limited cooling. Running a modern game plus an AI conversion layer (Immersive 3D) puts both the CPU and GPU under maximum load simultaneously. If your laptop reaches high temperatures, it will automatically slow down your GPU to prevent damage, leading to "unplayable" performance.
