This guide explains how to boost browser performance by making sure your computer’s dedicated graphics card (GPU) is being used, which is especially important for tools like cmBuilder. For users whose hardware includes a GPU. activating this setting solves the majority of performance issues.

Why It Matters

If your browser isn't using your GPU, cmBuilder will run slowly, like pedaling an electric bike with the battery turned off. We strongly recommend enabling your GPU when using cmBuilder.

Signs That Your GPU Isn’t Being Used

• cmBuilder shows GPU tier as 0, 1, or 2.
• GPU name says "internal" or includes "Intel" (Some Intel GPUs are okay, but often this means your dedicated GPU isn’t being used.)
• cmBuilder feels slow or laggy.

Further Actions

If after activating the GPU setting as described above and restarting the browser does not address the performance issues, or if the App Performance tab does not recognize that the GPU has been activated, try the following:

• Check the NVIDIA Control Panel to make sure there aren't any settings preventing hardware acceleration.
• Try updating the graphics card driver, as an outdated driver can sometimes cause issues.
