Poor performance in camaign (on Altis) and memory leak on Windows 10
Assigned, WishlistPublic

Description

I have an issue with performance in-game with windows 10 and the campaigns Resist and deliverance(20 FPS while playing on altis, i got between 40-60 on stratis).

The game seems to leak all over the "system" process ntoskrnl.exe (see capture).

I already fixed the Windows 10 Ethernet driver leak, the process only goes as high as 2 GB when I play Arma 3, it don't use more than 100 MB normally, on the main menu of Arma 3, the process is at 400 MB, then it goes up when i start a mission. {F26922}

Resist and Deliverance are not campaigns made by Bohemia Interactive. Are you experiencing low performance on official content?

Hello,
I tried in the showcase "tanks", the performance was good at the beginning, then my FPS dropped to 20 FPS when the combat started, probably when a lot of AI spawned.

The ntoskrnl.exe process was also at 1.2 GB, see second pic)

After making some tests, I noticed that this issue was here on every game.
After some research, I found out that Windows 10 Superfetch service is kinda broken, and take a lot of RAM and CPU. after disabling it, the memory leak was gone, and performance better.
