New Laptop - Troubleshooting a slow framerate on ASI120

starhopper

Hello Forum,

I have recently upgraded to a new (faster) notebook and the maximum frame-rate droped from 25 to 13fps. I need help troubleshooting this issue.

new notebook:

Asus Zenbook UX305FA

Intel Core i7 6500U

Windows10

256GB SSD

8GB RAM

1x USB2.0, 2xUSB3.0 with intels eXtensible host controller chipset

old netbook: HP netbook, 2GB, USB2.0, Windows 10 -> 25fps

I have tried the following things without improvement:

- shut off AVIRA Virusscanner

- take a friends ASI120

- another cable

- try all USB Ports -> same frame rate

- USB Traffic over 40 results in stocking video

- recording framerate is not lower than display framerate

- Firmware Upgrade -> no change

- turned Windows10 USB enery savings off

- updating ASI driver -> no change

- reinstall USB Chipset driver for intels eXtensible chipset

any suggestions?

Then I think you tried all you can do

there is no other way to improve it

What software are you using for video capture and/or camera control?

there are many of them

most popular one should be SharpCap or FireCapture

Sharpcap can test your disk write speed, can you try this test?

I've just discovered that if I set the frame rate limit in Sharpcap to 30fps (as I have done for as long as I can remember) the max frame rate I actually get from my 120mm is about 20 fps. If I set the frame rate limit to Maximum I get the expected 30 fps. Its taken me over a year to discover this...
