I get the same results on that page regardless of whether or not DisplayFusion is running.

Does it make any difference if you try a different keyboard? ]]> https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791#3 Thu, 20 Aug 2026 21:12:42 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791#3 DisplayFusion HyperX Alloy FPS ]]> https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791#2 Thu, 20 Aug 2026 20:21:48 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791#2 DisplayFusion What keyboard make and model do you have? ]]> https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791 Thu, 20 Aug 2026 09:06:54 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/keyboard-input-lag-while-using-latest-displayfusion-pro-steam-version/?ID=01a01e6c-5de1-7320-9be3-ae67be805791 DisplayFusion With the recent updates i started experiencing some visible input delays while running display fusion (for taskbar function mostly), i honestly don't know which version did it, because i didn't update it for like a year.

With sites like https://www.iobit.com/en/keyboard-latency-test.php i managed to identify that problem is indeed DisplayFusion (while it runs, there are input spikes to 1/60ms from 120ms while pressing mashing buttons) which doesn't happen if i turn DisplayFusion off. These spikes feel very off while typing.

Can't downgrade version because i use Steam version.

Any help? Debug export attached ]]>
