Thank you so much for reaching out to us, I am sorry that you are running into this issue, but I would be happy to assist!
First, I do want to advise you that all of our DisplayLink based devices are not recommended for gaming, as performance related issues like the one you are experiencing can occur. We make sure to point this out via the product pages and Amazon listings. This is due to the incompatibility of virtualized graphics drivers being utilized, and games not knowing the right communication factors when a dedicated or integrated graphics card is used in unison with the DisplayLink drivers and devices.
I would be happy to review the log files from our PlugDebug output to see if any driver updates or software installation may add a little better experience when utilizing the devices. When you have a moment, please head to www.plugable.com/support/plugdebug and send over the output of the PlugDebug application, as well as the Amazon Order ID Number associated with your product to email@example.com. Please include “Ticket No. 199605” on the subject line.
Thank you for your time,
Product Owner & Technical Support
