We've released a new beta with some changes here, can you try it out and let us know if the issue persists?


Seems alot more stable (for now), still have to make it run a while to see how it's really preforming, but no more random spikes in the I/O at least! I'll report back if I notice anything else. Thanks! :laugh:

Still, weird that it isnt preset in v11, so it must've been a recent change. I'll report once the next beta is out! ]]> RE: Weird behaviour since DF v12 https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#5 Tue, 20 Jan 2026 15:59:37 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#5 DisplayFusion It looks like that I/O read every 60 seconds is to read in a Windows UI culture file for some strings we need to read when the system language changes. We're updating it to cache for 60 minutes and using another method to detect if the system language changes. This fix will be in the next beta.

Thanks! ]]> RE: Weird behaviour since DF v12 https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#4 Thu, 15 Jan 2026 21:05:51 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#4 DisplayFusion Thanks for the update, I don't see anything unusual in the log. I will pass this up to our developers to take a look at next week to see what they can find out.

Thanks! ]]> RE: Weird behaviour since DF v12 https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#3 Thu, 15 Jan 2026 18:43:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#3 DisplayFusion Alright, the memory leak stopped happening with the new beta version, but it still does the weird I/O search on a steady basis (about once every min for about 1-2 sec). From what ive been able to skim through the log, it might be related to a screensaver i dont use anymore? Not exactly sure, but that's the only thing i can glean from it... ]]> RE: Weird behaviour since DF v12 https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#2 Thu, 15 Jan 2026 17:47:20 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/weird-behaviour-since-df-v12/?ID=019bbe2c-87b5-7593-955f-7613c9b12281#2 DisplayFusion Could you update to 12.0.2 Beta 7 again and send over a debug log for this issue?

It keeps on cycling like this endlessly for no apparent reason... This behaviour goes away if I reinstall the previous 581.xx drivers.

edit: i checked the threads themselves and they seem to call out a invalidation controller reset or something?

edit2: ... or rather, it STILL happens on the older drivers, but they are far less sever or noticeable. Still seem to be driver related.
It seems to stop leaking memory (at least) whenever i play a game, but the I/O and cpu spikes seems to still happening even then.

edit3: Ok, I downgraded DF to 11.1.1 and the issue stopped entierly. I guess i just had'nt been noticing it until now, but v12 seems to really not like my PC. ]]>
