I'm glad you turned off hardware acceleration. This usually corrects most problems we choppy screen recodings. The latest version now has a new setting that automatically disables hardware acceleration when starting a screen recording and it is rest back when you have completed the recording.
Here are the steps to use the automated hardware acceleration toggle feature:
1. On the Tools menu, select Settings.
2. Select the Performance tab.
3. Check the option Disable Hardware acceleration during recording.
4. Click OK.
If you recording a video from Windows Media Player then you will need to also turn off video acceleration.
The steps to turn off the video acceleration in Windows Media Player:
1. In Windows Media Player, on the Tools menu, click on Options.
2. Select the Performance tab.
3. Move the Video Acceleration Slider to None.
Choppy video is a PC performance related issue. If the above settings did not help, here are a few things you can try to increase performance:
1. Reduce the screen resolution of your monitor to 800x600 pixels or lower.
2. Reduce the color depth of your monitor to 256 colors.
3. If you are interested in recording a portion of the screen then try using Region recording or Window recording instead.
