Hi,
could you please try the latest beta version of SharpCap 4.1 to see if that is any better? See https://www.sharpcap.co.uk/sharpcap/sha ... p-4-1-beta
There have been some changes made to the beta recently to improve performance and responsiveness.
Other things to check are
* You are capturing to SER file in SharpCap? It's possible to set it up to capture individual frames to PNG files, which is slow (and probably not what you want!)
* Turbo USB should be set to auto or manually to maximum
* Make sure processing options (flat frame, dark frame, etc) are *off* in SharpCap as they can use extra CPU
It's also worth checking the CPU usage/frame rate when not capturing. If the frame rate is fine when just viewing the image but drops when capturing then it narrows down the likely causes to things related to saving the images.
cheers,
Robin
