One of the main causes of poor video recording performance is the speed at which your system writes data to the hard disk and very often this is caused by the hard disk itself. There are a number of things you can try in order to improve hard disk write performance and hence improve the RightBooth video recording performance
De-clutter. Remove unwanted files and free up some space on the drive. Run the Windows Disk Cleanup utility to remove unwanted files.
De-fragment. Older hard disks can end up having lots of fragmented files. Try de-fragmenting the disk. Run the Windows Disk De-fragmenter utility or better still, try a free de-fragment utility like Disk Defrag from Auslogics
Write caching. Run the Windows Device Manager. Open the Disk Drives branch. Right click on your hard disk drive name and select Properties from the popup menu. On the next panel click on the Policies tab. Tick the box 'Enable write caching on the disk'.
To improve performance further also tick 'Enable advanced performance' or 'Turn off Windows write-cache buffer flushing'. But please note that whilst these settings will improve disk performance, you will be at risk of data loss should the computer lose power, so in this situation you might need to consider a separate power supply.
If you still find that video recording is struggling to keep up you may need to reduce the recording size and/or reduce the recording frame rate within the RightBooth Settings, which in turn will reduce the amount of data that is written to disk during the recording.
Finally, try turning off any virus scanner applications and also close any other applications that may be running at the same time during the RightBooth recording session.
