About the issue of Media Capture.

In my scene, when Media Capture is not enabled, the frame rate stays stable at 80-90 FPS. However, when I add two in the Media Viewport Capture of Media Capture, the frame rate drops to 30 FPS when I click Capture, and sometimes it even falls below 30 FPS. I tried adding just one, and the frame rate became 60 FPS; adding another one dropped it to 30 FPS. Does Media Capture have such a big impact on frame rate? Is there any way to mitigate this?
