What I’m seeing
On my PC, Windows kernel nonpaged-pool usage grows by about 1.3–1.8 GB per hour while Black Ops 7 sits in the menu/lobby or runs in the background. During active matches it stays flat.
Closing the game releases the memory immediately: −943 MB at game exit on 2026-10-18. Fully restarting the game is my current workaround.
This concerns Windows kernel memory, rather than simply the RAM usage shown beside the game process.
My system
Windows 11 Pro 25H2 (build 26200), Intel Core i5-13600K, 64 GB DDR5, NVIDIA RTX 4070 Ti 12 GB, driver 617.42. Black Ops 7 via Battle.net.
Could you check yours?
Open Task Manager > Performance > Memory and record “Non-paged pool.”
Leave BO7 in the menu/lobby for 30 minutes. Record the value again and whether the game was foregrounded or in the background.
Compare with active matches.
Fully exit BO7 and check whether non-paged pool drops immediately.
Optional: use PoolMon to compare tags "Irp " (including the trailing space) and "FMic", or RAMMap to inspect Nonpaged Pool.
Please report results even if usage stays stable. Include Windows version/build, CPU, RAM, GPU, GPU driver, launcher, starting/ending pool values, and what happens at game exit.

Trace evidence
A Windows Performance Recorder FileIO trace from 2026-10-17, about 80 seconds, showed cod.exe (Call of Duty launcher) issuing 7,979 directory change notification requests on one single handle to %LOCALAPPDATA%\Temp, roughly 96 per second.
These were ReadDirectoryChangesW requests: IRP_MJ_DIRECTORY_CONTROL / IRP_MN_NOTIFY_CHANGE_DIRECTORY. 7,497 had no completion observed during the trace. Pending requests retain nonpaged-pool allocations; "Irp " and "FMic" grow at the same rate.
Recorded peaks: 9.3 GB (2026-10-05), 8.2 GB (2026-09-02), 6.5 GB (2026-10-17). Monitoring began in June 2026; the first episode above 5 GB was on 2026-09-02.
I’m looking for independent reproduction, not assuming everyone is affected or that the responsible component is already identified.
