[SOLVED] How to Enable Hardware-Accelerated Rendering in MATLAB 2025b

The old opengl command has been deprecated and replaced by rendererinfo.

In MATLAB 2025b, running rendererinfo returns the following:

ans = 
    GraphicsRenderer: 'WebGL'
              Vendor: 'Google Inc. (Google)'
             Version: 'WebGL 2.0 (OpenGL ES 3.0 Chromium)'
      RendererDevice: 'ANGLE (Google, Vulkan 1.3.0 (SwiftShader Device (Subzero) (0x0000C0DE)), SwiftShader driver)'
             Details: [1×1 struct]

According to MATLAB’s online documentation, if RendererDevice does not show a GPU name, it means rendering is on the CPU. The details field also confirms this:

HardwareSupportLevel: None

My system hardware is an AMD Ryzen 7 8845HS with integrated Radeon 780M graphics (no discrete GPU).
All dependencies are correctly set up, and the system can definitely use hardware acceleration:

❯ vulkaninfo | grep "GPU id"
                GPU id = 0 (AMD Radeon 780M Graphics (RADV PHOENIX))
GPU id : 0 (AMD Radeon 780M Graphics (RADV PHOENIX)) [VK_KHR_xcb_surface, VK_KHR_xlib_surface]:
GPU id : 0 (AMD Radeon 780M Graphics (RADV PHOENIX)) [VK_KHR_wayland_surface]:

❯ glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD Radeon 780M Graphics (radeonsi, phoenix, LLVM 21.1.4, DRM 3.64, 6.17.5-arch1-1)

However, MATLAB 2025b still reports software (CPU) rendering via SwiftShader.
Does anyone know how to enable hardware-accelerated rendering in this new version?

It appears you need to use an environment variable to change what device is used.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

I found solution: hardware acceleration can be achieved by adding `export LD_PRELOAD=/usr/lib/libstdc++.so.6`.
