Unfortunately, most webcams have a low-to-medium frame rate. After all, there are only so many things you can do with a front camera. It mostly boils down to video calls and occasional selfies. However, if your webcam is glitching, it may be caused by an overrun CPU (Central Processing Unit). Like most software, the camera performance depends on the speed of the processor. Here’s how to check if the CPU usage is at full capacity: 1. Type in “Task Manager” in the Search dialog box. Click to open. 2. Find your camera on the list of apps. 3. Check the usage capacity in the column on the right-hand side, under “CPU.” 4. If it’s anywhere near 75%, it’s probably causing the lag. After you’ve established the root of the problem, you have to make some adjustments. The simplest solution is to change your capture resolution from the default 640x480 to 320x240. You can also disable all advanced settings and make sure there’s enough light for your webcam.
