JcRabbit Posted October 9, 2019 Share Posted October 9, 2019 Hey Fiery! Not sure if this issue belongs here, but after installing the latest Windows 10 update (KB4517389 & KB4524100) I started noticing a general 'sluggishness' of the system (an Intel 9900K @5Ghz with an Nvidia 2080TI GPU and an Asus Formula XI Maximus motherboard) plus occasional video stutter and audio drop outs. This prompted me to run LatencyMon which showed me the system was running in the red almost constantly (3000 - 5000us + interrupt to process latency). The culprits seemed to be dxgkrnl.sys (highest reported ISR routine execution time) and the Nvidia Windows Kernel Mode Driver nvlddmkm.sys (highest reported DPC routine execution time). I installed the latest Nvidia and Realtek drivers, rebooted, no change. So I started exiting all running monitoring and control software (at first I thought it was Corsair iCue given the recent problems) and the only thing that fixed it was exiting Aida64. I use Aida64 primarily for the OSD, where I display system and hard drive temperatures, fan speeds, voltages, APC UPS stats, etc... I tried un-checking anything related to the GPU (GPU Diode and GPU fan speeds) and restarting Aida64 but that didn't help either. I also run MSI AfterBurner, but exiting has no effect on the high system latency while Aida64 is running nor does it increase latency if I run it without Aida64. I'm not sure if the high latency was present before (might have been) but if it was I didn't notice it as it didn't cause audio dropouts. As I stated above, only started noticing this after the latest Windows 10 update. If I exit Aida64, none of the latency values ever go above 250 us (usually fluctuate between 30-110us). Same thing if I hide the OSD in the Aida64 tray icon, of course. Running Aida64 Extreme v6.10.5200 build date 23/09/2019. Any ideas which sensors might be causing this and why? Anything you want me to try? Quote Link to comment Share on other sites More sharing options...
