When I'm not moving my cursor around I easily reach my capped FPS but as soon as I move the cursor it beings to stutter and goes down to half with lots of fluctuation. ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#9 Thu, 30 Apr 2026 20:30:58 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#9 DisplayFusion Can you try out our latest beta and let me know if the issue persists? ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#8 Wed, 29 Apr 2026 19:41:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#8 DisplayFusion Here you go, hopefully you guys can figure it out!

The game I've been having the issue with as of late is Slay the Spire 2 but it definitely happens in many games I play to the point that sometimes I just close display fusion while playing stuff. ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#7 Wed, 29 Apr 2026 17:52:12 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#7 DisplayFusion Could you send me a copy of your troubleshooting info?

Yeah some games don't like when we hook into them. Did you disable the hooks for just that game via the compatibility tab, or globally through the advanced settings?


I had the same issue with Division 2. Disabling Application Hooks in Compatability as you suggested DID work. ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#4 Tue, 10 Feb 2026 17:08:42 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#4 DisplayFusion

I had the same findings as OP. it took me months to realize the problem was displayfusion. I used the compat settings to disable everything since I don't use DF for any of that. Maybe there should be some warning or something, considering it is on sold on Steam

Agreed. It took me ages to realize it was DF as well. To the point of doing a boot drive format, installing software then testing a game before creating a restore point and installing another piece of software, one by one. ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#3 Mon, 09 Feb 2026 10:42:00 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#3 DisplayFusion I had the same findings as OP. it took me months to realize the problem was displayfusion.

When moving my mouse in games I will get extreme stutters/fps drops caused by display fusion eating up the CPU. The higher the polling rate on the mouse, the worse this stuttering becomes. At 500hz, the issue is almost fixed, anything above 1000hz it becomes unplayable. I've heard that disabling application hooks fixes the issue, but that disables the main reason I use display fusion. ]]>
