DWM Latency IO Tweak?
Hi, long time lurker of this thread, and also a big audio nerd.
Happy with all of your contributions through the years, even if it gets a little dubious and messy at times. Thanks to all the experts for their input and to the tweakers for bringing up new topics and interesting new options.
I'm on Win10, 100 hz display, with lord knows how many tweaks for gaming and optimizations for live audio playback. Mostly been following the likes of Melody and CHEF-KOCH lately.
I recently was messing in regedit, since I've been trying to address some audio latency issues (which I've bettered by normalizing my voltages in BIOS, but still present) and wondered if anyone knows what these do, and if they're worth modifying for input/audio latency.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Win dows NT\CurrentVersion\BackgroundModel\BackgroundAudioP olicy
AllowHeadlessExecution = 1 //original is 0
AllowMultipleBackgroundTasks = 1 //original is 1 (might try another value sometime)
InactivityTimeoutMs = FFFFFFFF //original is 6ddde (I think, oops)
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Win dows NT\CurrentVersion\Windows
DwmInputUsesIoCompletionPort = 0 //original is 1 (I suspect this could be big for input response)
EnableDwmInputProcessing = 0 // original is 7 (curious to why original is 7 and not 1)
My cursor movement is now a dream, it actually felt really weird at first, kinda like cracking headshots without interpolation when you've been used to it.
Of course, I'm not claiming this was the actual cause (or that these even do anything), so I wonder if anyone knows what these actually do or has any experience with these. DWM disabling is a big deal for some in this community, so you might want to take a crack at it.
I await your hate comments with anticipation.
