Let me know if you need any additional information. Monitors: 3x Dell 2715H 2560x1440, running in extended display mode. Motherboard: ASUS ROG MAXIMUS VIII HERO LGA1151 RAM: 32GB Corsair Vengeance LPX DDR4 3000MHz C15

I've found a number of threads on other forums of people having issues with dwm dating back to Windows 7, but I haven't found any solutions that solve my particular issue.ĬPU: Intel Core i7-6700K (default clocks)

I've performed a windows reset (remove all files version), but have not done a complete reformat/install from ISO.

I've updated chipset and other hardware drivers to the latest version provided by Asus, intel, etc. I've cleaned out all nvidia drivers and reinstalled the latest version. I've had the same issues manifest after restarting the system and just letting it sit idle for a while.Īntivirus/malware scans (no infection). Skype and Skype for Business, Excel, Discord, Steam, and Sublime Text 3 are also usually open. I have Microsoft Outlook open at all times. Between Chrome and Firefox I usually have 100+ tabs open and 8-10GB of RAM dedicated to those browsers. The time it takes for the responsiveness to degrade ranges from 30 mins to a couple hours. This started a few months ago, with no significant changes to the PC configuration (hardware or software) at that time. Before restarting dwm.exe, its CPU usage is usually around 12%, memory 200-300mb, gpu 2-3%, nothing that stands out to me as a huge problem, and yet restarting it fixes my issues. The moment dwm.exe is restarted everything returns to what I would consider "normal" speed for 60hz monitors and a PC with these specs, which is a very noticeable difference. hover effects on text/buttons) lag behind the cursor event by close to a second while window movement, game inputs/frame rate feel like they are moving at less than 20fps. At its worst, interface interactions (eg. Interface interaction and display responsiveness degrade until I manually restart the dwm.exe process (task manager > details > dwm.exe > end process tree).
