andyk Posted May 11, 2015 Share Posted May 11, 2015 (edited) try a better/faster card Thanks a ton for deciphering the cause. Really frustrating. I find it almost unbelievable that MS ships a product that can't use it as, to quote PassMark, "The low to mid range chart typically contains video cards that are a couple of years old and includes . . . better performing Integrated Display Adapters from Intel, Asus and other manufacturers." Anyway PassMark gives the GeForce 210 a score of 184 which is half way down the chart. How much faster do I need to go? AndyPS. Found this thread with similar issues to mine and which I see you contributed to. https://social.technet.microsoft.com/Forums/windows/en-US/6884366d-6759-4ab9-89c5-fd6af8008b28/dwmexe-starts-consuming-lots-of-cpu-when-machine-is-idle?forum=w8itproperf Edited May 11, 2015 by andyk Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted May 14, 2015 Author Share Posted May 14, 2015 the other topic was a different issue. Try different nVIDIA drivers (also older ones, which where optimized more for so old cards). 1 Link to comment Share on other sites More sharing options...

BobsBurgers Posted June 14, 2015 Share Posted June 14, 2015 (edited) I must be stupid because I can't find a version of Windows Performance Toolkit to download for Windows 7. There's a page for Windows 7 downloads on the microsoft site: https://technet.microsoft.com/en-us/windows/windows-7-downloads.aspx but when I click on Windows Performance Analysis Tools: https://msdn.microsoft.com/en-us/library/hh162945.aspx It says that it only ' Applies To: Windows 8, Windows 8.1' Any tips? edit: Never mind, apparently it works on Windows 7 too. It doesn't have as many graphical features as the OP listed but it still works. Microsoft should really update the page for the toolkit so other idiots like me don't get confused Edited June 15, 2015 by BobsBurgers Link to comment Share on other sites More sharing options...
andyk Posted June 17, 2015 Share Posted June 17, 2015 I've fixed this now. Quite separately I had a problem with low (less than 500k) network throughput. After having tried various remedies I found that setting my card from 'Auto' to '100M full duplex' solved the problem. Since then I've also had no further problems with dwm and high cpu / dpc.

fliperpl Posted June 27, 2015 Share Posted June 27, 2015 (edited) Hello guys. I have trouble with DPC latency and mouse inputlag-feel like.Here is my Latencymon :http://imgur.com/jVOXJauhttp://wklej.to/ANdHWWhat did i try : what i have done to try fix :- followed "performance tweaks" tut from guru3d- fresh install windows 7 and diffrent drivers- using additional software what is forcing up raw_input instead of using from game- i change GPU and soundcard to MSI-mode - disable HPET in windows- change USB ports- disable everything in bios (unused ports etc and energy saving things)- disable overclocking- enable IRQ control by windows (in bios)- change ram (from a-data 2x2gb 1.65v to crucial 1x8gb 1.5v)- reseating CPU- In the meantime i change GPU from gtx460 to gtx660. Ofc i did clean install with DDU- i did use resolution timer- changed HDD from intel to Jmicron controller- i have full performance in nvidia drivers and windows- my computer its not overhearting (gpu max 60C,cpu max 65,motherboard 45-50C)- i borrowed PSU thermaltake SE 530W for testing- i did change LOD settings in mouse- diffrent voltage amplitude in bios- unplug xi-fi music- disable integrated sound card and ethernet- i changed motherboard from Asus P7P55D to intel PD55KG- i replaced CPU to another one xeon x3430 Propably i missed half of things that i did, but i dont remeber everything. It was just too much what i see : - in lower resolutions like 1280x1024 its not so much noticeable,but still- low FPS in smoke's in CSGO, flame and sometimes when flash blinds me (like 100fps. Normal is 250-400fps in everything else)- unstable pooling rate when playing catched in mouse movement recorder MY current spec is : xeon x3430 @ 3.6ghz 1.29v (was holding intelburntest and prime95 in 1.305v without any problems)Intel PD55KG 200bclk1x8gb crucial ballistix 1600mhz cl9 2tOCZ SXS2 600WCreative Xi-Fi music + pax drivers + integrated soundcard Genius ImperatorZowie FK1 + a4tech x7-700mpAcer G245HQ @ 75hz fhdspeakers Genius sp-hf1800amicrophone natec snake blackW10 64bit last build - at 8.1 and 7 same issue help :/ Edited June 27, 2015 by fliperpl Link to comment Share on other sites More sharing options...
Matirep Posted June 29, 2015 Share Posted June 29, 2015 (edited) Hi Andre, luckily founded your guide, this is driving me nuts, please help me One of my cores is always at 80%, dunno why, tried to diagnose by myself but Im running 8.1 and not sure which graph is the one.Im up to date with drivers from AMD (GPU, and this one), still getting drops on almost everything (gaming, movies, youtube). 3 DPC's attached just in case. Let me know if something's wrong with the link/filehttps://mega.nz/#F!WQRBXJKL!NJFA9tmIT5MHK3Hz3hBDbA Edited June 29, 2015 by Matirep Link to comment Share on other sites More sharing options...

saberbros Posted November 30, 2015 Share Posted November 30, 2015 Dear Andre, I appreciate the guide and I followed it to the letter. However, I honestly have a very little idea as to what most of the data in the text documents actually means. I have attached two documents and am hoping you can help me out. Thank you for your time! fileversion.txt dpc.txt Link to comment Share on other sites More sharing options...
Tripredacus Posted December 1, 2015 Share Posted December 1, 2015 From your dpc.txt, the ones on high end are relating to these: - networking - usb - hard drive - McAfee Link to comment Share on other sites More sharing options...
jdennis187 Posted February 26, 2016 Share Posted February 26, 2016 (edited) Hello Andre, Is this thread still going? I am having the similar issue. Random "system" cpu ramp ups to 10-20% of my Core i7 920 system. I have attached a trace though I don't know how this trace really works. I don't know if it is valuable because I am not sure if it was running while I was lagging. Let me know what you think thanks! Trace: https://dl.dropboxusercontent.com/u/66927202/DPC_Interrupt.zip EDIT: I have posted a second trace which I assume has data from when it was lagging here: https://dl.dropboxusercontent.com/u/66927202/DPC_Interrupt2.zip Edited February 27, 2016 by jdennis187 Link to comment Share on other sites More sharing options...
