To record smoothly on a low-end PC, the goal is to offload as much work as possible from your CPU and reduce the total number of pixels your computer has to process. 1. Core Video Settings
: Use Bilinear for the lowest CPU usage, though it may look slightly blurry. Bicubic is a good middle-ground compromise.
: Downscale this to 1280x720 or even 854x480 . Lowering the resolution is the most effective way to save resources.
: Set this to your monitor's native resolution (e.g., 1920x1080 ).
These changes provide the biggest performance boost by reducing the workload on your hardware.
