Low Frame Rate with ZWO174MM
Posted: Sat Oct 28, 2017 3:33 pm
Hello,
I have a ZWO174MM, and I am seeing a frame rate of 20 fps at full resolution using SharpCap 3.0 (latest update and camera drivers). The camera is advertised to take 165 fps. My laptop is a new Alienware running the latest of Windows 10. My camera is plugged into USB3.0 and the data is being saved to a SSD drive. I downloaded USB Device Tree Viewer and installed it on my machine per Gary Palmer's suggestion. Below is the result for my camera. Please help. Thank you!
