1/5/2024 0 Comments Dwm exe windows 10Although, when testing in-game, and constantly alt-tabbing from full screen and back, it would seem that, sometimes, the dwm.exe had to be restarted in order to get the effect (no need to leave the game, just service restart and then alt-tab back to the game). Changing the states of any other priorities was not needed. Through the Process Hacker, the Priority was set to Idle. Recreated the effect with only one DWM priority. Don't worry about Command Buffer as it should be off by default. Without one or another, I have struggled to recreate the effect.Īlso, maximum pre-rendered frames should be at one, obviously. 2) Use NV Profile Inspector and set: Frame Rate Limiter Mode - Limiter V2 Force Off Frame Rate Limiter - 0x00200000 PS_FRAMERATE_LIMITER_DISALLOWED. 1) Set the DWM priorities to the lowest states as described above. In order to get the effect you need 2 things. I have double-checked some variables and done some additional tests. NV Profile Inspector (Maximum pre-rendered frames - 1 Maximum frames allowed - 0x00000001 Frame Rate Limiter Mode - V2 Force Off Frame Rate Limiter - 0x00200000 PS_FRAMERATE_LIMITER_DISALLOWED MAX_PENDING_CMD_BUFFERS - 0x00000000 Off Enable Ansel - 0x00000000 ANSEL_ENABLE_OFF) NVCP (V-Sync - Force ON Triple buffering OFF G-Sync - ON Resolution/Color/Scaling settings - NV default) Don't worry, they do reset to defaults after system reboot.Īcer Predator XB241H OD- Extreme fps through RTSS) In the Process Hacker utility find the dwm.exe, then right click and set: Priority to Idle I/O priority to Very Low Miscellaneous > Page Priority to Very Low (page file priority, but for good measure). However, I have noticed that the better way, is to do it through the Process Hacker 圆4 utility (seems I can get more consistent results). You can just go to the Task Manager > Details > dwm.exe > right click > set to Low (works straight away, no need to reboot or anything, you can even alt-tab from a game). Nevertheless, could anyone with a G-Sync monitor or Rift, do me a favor and test something out please? Could you change Windows 10 DWM priorities and tell if you notice any difference in image quality (clarity, input lag, blur)? I don't know if it is just my config/system or something that would benefit some other people, but would like to find out. I think that different display managers behaving differently (unfortunately, in Win 10, we can't completely disable DWM, however, we can set it to the lowest priorities, which (just a guess) might somehow restrict it from interfering with the pipeline). All it took was changing dwm.exe (Windows Display Manager) priories to the lowest possible values (EDIT: some NV Profile Inspector settings are also needed). Tested on various openGL and D3D, old and new games, as well as with Oculus Rift (had a very noticeable improvement, maybe due to the lower persistence). Done some additional tests, and strangely enough, I did eventually get improved results in Windows 10 (much clearer and responsive image). Apparently, some of the games in Linux, have produced a better image clarity. I dual-boot Win 10 and Linux and sometimes like to test and see how the same games perform in different OSes. Searched through forums, couldn't find anything specific about that.
