Drastic drop in FPS
Posted: Sun Aug 04, 2019 6:33 pm
I'm having trouble understanding what is going on with my frame rate when using Sharpcap3.2 and my asi224mc while planetary imaging. I'm hoping some of the pros on this forum can explain what's going on and if I need to do anything different.
I'm using an exposure time of ~2.2ms and a ROI of 640x480 which is giving me a frame rate of ~130fps. My frame rate holds steady for the first 1600 frames with 0 dropped frames. After 1600 frames my frame rate drops to ~30 fps and I'm dropping a massive amount of frames. When I stop the capture a window pops up saying that it's writing the buffered frames, which is over 1000 frames. I've turned off the High Speed mode setting and adjusted the Turbo usb mode with varying amounts of improvement.
Should I be worrying about this being that there are a significant amount of frames that get added during the buffered frame writing process?
