CPU utilization spikes when running applications in full-screen mode.
CPU utilization spikes when running applications in full-screen mode.
When I turn on Vsync and unlimited FPS, my CPU usage goes crazy (full screen) with a Ryzen 5 1600. However, when I am in windowed borderless mode, it is fine. When I turn on Vsync plus a 60 FPS limit (full screen), the game is smooth and my CPU usage remains fine. It's especially noticeable in The Witcher 3. Is this normal?
Activating Vsync compels your graphics card to maintain a frame rate synchronized with your monitor’s refresh rate. For example, a 60Hz display will be limited to 60 frames per second, and a 120Hz display will target 120 fps. Consequently, enabling Vsync alongside an unlimited frame rate setting can lead to compatibility issues.
Enabling Vsync forces your GPU to maintain frame rates synchronized with your monitor's refresh rate. For example, a 60Hz monitor will be capped at 60 frames per second, and a 120Hz monitor will be limited to 120 frames per second. Consequently, activating Vsync alongside unlimited frame rate settings can lead to issues.
