Hello all,
I’m at wits end with an annoying problem. Hopefully someone can shed some light on it.
I have a brand new gaming laptop, with an i7-10750 6-core CPU, 32 GB DDR4 ram, and Nvidia RTX 2060 GPU with 6bg of memory. Two 1TB M.2 NVMe SSDs. Windows 10 is at 20H2 update, and all firmware and software up to date.
The problem is the Desktop Window Manager (DWM, as seen in the processes tab of task manager) will pretty rapidly (within 10-15 minutes) climb from a normal 108-200 mb of memory usage, to insane percentages of memory. I flew for 45 minutes the other day, and it had 7 GB (yes, GB, not MB) of memory used for DWM. Once quitting MSFS2020, it does not continue to climb, but also will not go back down.
I did some investigating and found it’s ONLY MFSF2020 that causes this, and only when the ATC window is on my second monitor. I have two screens, so why not put that window on the second one, I thought… Well…I guess it causes problems.
I have tried the following to remedy this.
-Updating windows from version 2004 to 20H2.
-Updating Nvidia drivers from 456.xx to 460.89
-Running integrity check on RAM
-Running windows diagnostics
-Running full virus scan with my A/V and from Eset online
-Running MS System File Checker (sfc scannow)
-Changing Virtual Memory Paging size to recommended size vs. auto managed size.
-Contacted laptop manufacturer (they had no idea)
-Contacted Microsoft (they had me do the same basic things I’ve already done)
-Lots of googling.
Seems like a common problem, but no clear answers.
The real kicker is that it doesn’t always have this issue. Some days I can fly with the ATC window on my second monitor and DWM will sit happily at 108mb the whole flight. I change nothing, boot up the next day with all the same settings and same running software, and it will chew through gigabytes of memory.
The ONLY solution I’ve found is to not put the ATC window on the second screen. Which then defeats the purpose of having two screens. Not ideal at all.
Thank you for any help!
