Nealius Posted July 27, 2023 Share Posted July 27, 2023 Maybe it's always been there and I'm just now noticing it, but whilst having some laggy mission editor performance I noticed this in both MT and ST versions of DCS: Any time DCS is running and in-focus, explorer.exe is up to 25% usage. It doesn't matter what I'm doing in DCS, it's always there and eating up processing power. If I alt-tab so that DCS is out of focus, or close DCS entirely, explorer.exe drops to typical 0% background usage. Why does explorer.exe get so active while running DCS? I've never seen this behavior with other games or software. Link to comment Share on other sites More sharing options...

Tacview disabled. I killed all processes I could think of to kill. Simply sitting in the DCS main menu causes explorer.exe processor usage to increase. Checking the disk usage I get NVcontainer.exe writing to NTFS log and GEForce Experience Log on my OS drive.

Disabled all Geforce Experience applications. Sitting on DCS main menu and not doing anything else explorer.exe shows up to 26 usage until DCS window is out of focus. It returns to 0. When DCS is in focus again, back up to 26. Exit DCS, back to 0. Dxdiag and log attached. DxDiag28JUL.txt dcs.log 1 Link to comment Share on other sites More sharing options...
Flappie Posted July 28, 2023 Share Posted July 28, 2023 Hi. You should use Windows Resource Monitor to find out what explorer.exe is doing while DCS is up. Click the "Disk" tab, and select explorer.exe. Run DCS, then Alt+Tab back to Resource Monitor. Check the bottom list: it shows all files being accessed by explorer.exe (or any other program you select in the top list). Have you by any chance enabled Windows automatic files compression or something else other than the ordinary? Don't accept indie game testing requests from friends in Discord. Ever.

Nealius Posted July 28, 2023 Author Share Posted July 28, 2023 The Disk Activity list is showing empty. However, I discovered that if I change the DCS resolution so that it's windowed on my monitor then explorer.exe is silent. When it runs full screen, explorer.exe usage activates again. On all my drives I have "compress to save disk space" unchecked. "Allow to be indexed" is checked. Should I uncheck that as well? 1 Link to comment Share on other sites More sharing options...
Flappie Posted July 28, 2023 Share Posted July 28, 2023 You can give it a go but I don't think it will solve your issue. Do you have OneDrive running? If so disable it and see if that changes anything. Don't accept indie game testing requests from friends in Discord. Ever. Link to comment Share on other sites More sharing options...
Nealius Posted July 28, 2023 Author Share Posted July 28, 2023 OneDrive is installed but I've never ran it. I found something interesting though. This seems to be linked with resolution and/or full-screen vs. windowed. My monitor is 1080p, but I have it upscaled to 3840x2160 to get rid of aliasing/fuzziness when getting screenshots and video footage. This is the behavior I noticed after experimenting with DCS resolutions: - 3840x2160 full screen; no issues - 2560x1440 full screen; no issues - 1920x1080 windowed; no issues - 1920x1080 full screen; explorer.exe using 20~25% CPU 1 Link to comment Share on other sites More sharing options...
