garybrun Posted February 8 Share Posted February 8 (edited) For those of you who have latency problems. Its took me ages to find a solution to fix the high system load that kept popping up in my windows 11 installation. I have now solved it.. its a long process of things to optimize but it works fine now. Hope some people find it helpful.

Jim Roseberry Posted February 8 Share Posted February 8 FWIW, You do NOT want to disable Hyper-Threading. That was necessary many years back... with the very first implementation. Hasn't been necessary since Steinberg and other developers caught up (shortly after). 5 Link to comment Share on other sites More sharing options...
Simeon Amburgey Posted February 10 Share Posted February 10 Some good (and scary ones) in this video. I ran a couple of these, especially the NVIDIA Debloat and driver slimming suggestions, along with the DYNAMIC TICK suggestion. Honestly though, my biggest update was finally being able to add an RME Babyface Pro FS to my setup, it has been an absolute dream for me here. My past livestreams have been rock solid and I am able to run everything at 128 buffers which nets me around 2.7 ms roundtrip latency. It has been such an eye and ear opening experience with this and now I know first hand what everyone has been talking about all of these years. Here is what my latest Latency Mon is looking like: 2 Link to comment Share on other sites More sharing options...
garybrun Posted February 11 Author Share Posted February 11 Hi Simeon. I have managed to get mine quite low now. It is a game changer. There is one more tweak that is not on the list.. but makes a huge improvement.. Will post it up. 2 Link to comment Share on other sites More sharing options...
garybrun Posted February 11 Author Share Posted February 11 (edited) @Simeon Amburgey This is the one... on the high performance power plan. Crazy massive change.. https://www.youtube.com/watch?v=n9xAG3nb9XQ I am now running all of my projects on my UAD with latency at the lowest of 32. Not even a twitch and loads of plugins on.

mettelus Posted February 12 Share Posted February 12 That OP is a pretty comprehensive list worthy of being a reference guide! The only one I didn't see explicitly, although would be covered with services, is disabling "Automatic network discovery." For folks who do work staying connected, that is often the biggest latency hitter as it pings every 4 seconds or so. You really don't want your computer trying to connect with "everything in range" on its own anyway; that should be a very deliberate pairing for simple security reasons. 3 Link to comment Share on other sites More sharing options...

Gary, I ran that particular tweak and it did seem to make a big difference. Here is another video that goes into a possibly more specific breakdown of the Ultimate Power Plan settings: Again, I have to go back to the dramatic difference my stability became after installing the RME interface and drivers. It would be interesting to see if things held steady let’s say if I went back to the Arturia or Focusrite. That might be something to investigate, but for now I am feeling a confidence in my system that is hard to explain. Joyfully, Simeon 1 1 Link to comment Share on other sites More sharing options...
garybrun Posted February 13 Author Share Posted February 13 I cant believe I can run Cakewalk at 32 buffer size and loaded with plugins. Doesn't stall at all. I wish I had found these things out years ago. ? 1 Link to comment Share on other sites More sharing options...
Danny Bullo Posted February 13 Share Posted February 13 Thanks for your post, garybrun! Which tweak would you say is the most dramatic in terms of DPC Latency? I tried most of the "classic tweaks". I'm interested in - Set Processor performance time check interval - 5000 - Set process scheduling to long quantum Thanks Bullo Link to comment Share on other sites More sharing options...
garybrun Posted February 13 Author Share Posted February 13 (edited) I just did the hacks in the first video and it solved my wdf problem, i found the the check interval hack... which decreased latency even more. I can guarantee that the hacks in the first video work. I wished I found these years ago. I am now running at the lowest buffer size (32) with no problems at all. I'm not searching for any more hacks... I'm rock solid. ? Edited February 13 by garybrun 4 Link to comment Share on other sites More sharing options...
Starship Krupa Posted February 14 Share Posted February 14 I haven't watched the first video yet, although I will, just to check it out. The recommendation to disable hyperthreading is a red flag, though. I've tested that one pretty thoroughly and modern audio software seems to prefer having those virtual cores. To the point of the same Cakewalk project not even being able to play when hyperthreading was disabled. At least, if you try it, don't do so blindly, test before and after with a large project with lots of plug-ins to see if you get a latency improvement with no other negative consequences. There's a lot of outdated folklore floating around in the Windows audio community about what settings to enable or disable in BIOS. It neglects to consider that technologies that may have not worked so well when they were first introduced but then got the bugs worked out by the hardware manufacturers and Microsoft. Up until a couple of years ago, the Cakewalk Reference Guide even suggested disabling ACPI in your BIOS 'cause that darn plug 'n' play just didn't work right. That advice is about 25 years out of date, but it stuck around in a company's documentation. The one about setting processor performance time check interval, though, whoa doggie. I never heard of that one before and at least in my initial testing, it's cut my LatencyMon average measured interrupt to process latency in about half. Remains to be seen how that will affect actual use of programs, but it seems impressive at least for now. The other one, setting process scheduling to long quantum, I'm much more skeptical about. I Googled it and it seems like it would cause problems. I'm not even going to try that one. This topic also inspired me to go in and double check one of my favorite tuning things, which is to set as many devices as possible to use message signaled interrupts. This has to do with our old, old configuration bugaboo, IRQ's and what happens if two devices wind up sharing an IRQ. On my system, my motherboard loves to assign both my Firewire adaptor (which of course connects my audio interface) and my nVidia GT 1070 to IRQ 16. Fortunately, the nVidia supports message signaled interrupts, but somehow it got disabled, so I just turned it back on. Thanks for posting these tweak guides. With all of them, do your own independent research via Google, don't take any single person's word for it (except maybe Jim's ?). If you don't understand what it does, make notes about what you do and test your system before and after. If it has no effect or a negative effect, back the change(s) out immediately. 4 Link to comment Share on other sites More sharing options...

Its not just the author I have followed I've checked around. Forget the HT... it all works and I have a massive improvement. The secret is to take what you can use and what you can not. the proof of the pudding is in the eating. Im stuffed ?
