No, I still encounter massive lag spikes with dwm.exe after a few weeks of uptime, and restarting the process fixes it. However, I get lag in the Windows UI itself, not games. I think it has something to do with one of my monitors always disconnecting from the computer when it goes to sleep, so Windows acts like I'm constantly plugging and unplugging the monitor multiple times a day, for weeks. Leaks like 200-500MB+ each time, and dwm.exe is often using close to 3-4GB when I kill it.
