All background programs suddenly slow when DCS is open after Windows 11 upgrade

[Onslott]

Hello All,

As the title states, after recently upgrading to Windows 11, I am noticing that background programs are noticably visually and operationally slower when clicked into the DCS window. I firsted noticed the SRS overlay would blank out, and then my Streamdeck would have up to 5 second input lag times, and discord would blank out as well. While in DCS, I would also mopve my cursor over a Chrome window and would see that scrolling is also slow to respond. Specs are: i9-13900 KF, 4090FE, 68GB DDR5. I understand that I could go back to Windows 10 as a quick fix, but seeing as support will no longer be available later on, I might as well just figure this out now.

I have tried:

• running everything as admin
• disabling launcher
• restarting
• updating drivers
• closing everything but DCS and normal background programs that I run with DCS

I am running Process Lasso Pro with the Bitsum Highest Performance profile enabled as well.

Any ideas/solutions would be greatly appreciated!

Try disabling Hardware Accelerated Graphics (HAGS) if you haven’t already.

Thank you, this was the issue! However, Windows 11 24H2 would constantly crash the Settings>Display>Graphics window - no idea why and was super frustrating to try to figure it out. I went back to 23H2 and was able to turn it off.
