Hardware Acceleration Camtasia Recorder > Tools > Options > Capture tab > Disable display acceleration during capture The option to disable hardware acceleration during capture is only available on Microsoft« Windows XP or earlier operating systems. Screen recording can exhaust the CPU resources which can result in low frame rates or sluggish performance. Tool low of a frame rate can make videos appear jerky. If the system resources are exhausted, the mouse cursor or background applications may run slowly. After recording, you may see a black box instead of the recording. This is evident on slower systems, when running CPU intensive applications and recording large areas of the screen. Disabling hardware acceleration greatly reduces CPU utilization on Microsoft« Windows XP. Some applications require hardware acceleration to run properly. Games, CAD programs, and TV cards are a few examples. Try other methods to reduce the CPU: Decrease the size of the recording area. Lower the capture frame rate. Use a faster computer.
