Windows OS animations run on CPU without using IGPU or GPU.
Windows OS animations run on CPU without using IGPU or GPU.
Windows OS animations work with CPU or GPU/IGPU depending on the situation. When opening or closing software, the start menu and Telegram effects run using either the CPU or graphics card, not exclusively one over the other. Whether your i5 9400 F is affected depends on which part handles the rendering. If you notice performance changes, it’s likely tied to GPU usage rather than CPU alone.
You prefer your GPU to stay idle because animations are handled by your GPU, but only minimally—just a tiny percentage—and this won’t impact its performance. They won’t affect your GPU’s power consumption significantly; it might use a bit more in the case of brief animation use, but that’s negligible. The real impact would be if there were any animations while gaming, potentially causing a slight drop in FPS. Overall, having animations on doesn’t harm your GPU’s efficiency.
This feature applies only to Telegraph and not Windows. It allows animations inside Telegraph, but how it animates or draws its windows can differ. The choice you highlighted indicates the use of an ANGLE graphics backend, meaning Telegraph employs a rendering engine for its windows and contents. For more details, refer to the Wikipedia entry: https://en.wikipedia.org/wiki/ANGLE_(software). You'll notice that the rendering engine may utilize DirectX, OpenGL, Vulkan, or even switch to CPU if the graphics card is insufficient or unsupported.
