- Dpc latency latencymon. But what is DPC latency? DPC stands for Deferred Procedure Call. sys behaving itself, with peak DPC times well within acceptable limits. 40 WHQLSupir barunya gan, detail dan download : https LatencyMon now shows nvlddmkm. If you’ve Latencymon introduces additional latency on modern windows/processor schedulers which can undercount and overcount durations due to the nature of how it tracks the latency, one thing to note that most people don't look at, is the Count of times that the DPC was at that level, which is shown on the Stats tab of latencymon, quite common for Feb 2, 2026 · LatencyMon checks if a system running Windows is suitable for processing real-time audio and other tasks. sys DPC time reduced (~429 µs), but D2R SFX issue persisted. 74). sys, and my network latency/bufferbloat during download tests spikes to over 130 ms. Let LatencyMon run until the audio problems are observed, even if it takes several hours. Used DDU in Safe Mode and reinstalled NVIDIA driver clean (From 591. . When the GPU is enabled, LatencyMon shows very high DPC times (up to 4000–5000 µs) caused by nvlddmkm. The 3090 was okay (still bad DPC latency, but not this bad). Priority 2 is eliminating background interference. 3. Users who don't need the much-improved graphics horsepower of the Core Ultra X7 will find the less expensive Core Ultra 7 option much more attractive especially if upgrading from an older XPS 13 I have the same issue as you guys. The minimum time for collecting DPC latency data should be 15-20 minutes to get a sufficient set of data for a complete analysis. It turns out, for legacy hardware like the HP xw8400, the less "smart" your graphics driver tries to be with buffering and multi-threading, the better for real-time audio. This started to happen just a couple of months ago for me and to this day I have not managed to fix it. Sometimes, the simplest solution is the most effective. After reinstall, LatencyMon improved significantly (“system suitable”), nvlddmkm. Asus and Intel are starting off the year strong with the debut of the Core Ultra X7 358H. DPC latency observations: Latencymon users reported increased DPC latency in some configurations; if you rely on ultra‑low latency audio or DAW workflows, validate driver behavior before committing. LatencyMon analyzes the possible causes of buffer underruns by measuring kernel timer latencies and reporting DPC and ISR execution times as well as hard pagefaults. Oct 23, 2025 · How LatencyMon works — the technical essentials LatencyMon runs as a monitoring tool with administrator privileges and samples kernel timer latencies, ISR and DPC durations, and hard page faults over a test interval. 4090 kills audio. In its purest form, it is the part of your Windows system that handles driver efficiency. In the past the DPC latency was an annoyance, but did not hurt me much (it used to only hurt folks working a lot with audio, think editing and such), but every since upgrading from the 3090 to the 4090 I cannot use my USB based audio DAC. sys", so Windows is also to blame here. 86 to 591. sys on my MSI 3080. Spent hours with Focusrite trying to figure my sound card issue and the DPC routine in LatencyMon shows HUGE execute timers for nvlddmkm. Notebookcheck reviews the Lenovo ThinkPad P16s Gen 4 AMD, a 16-inch workstation laptop with the powerful 12-core CPU AMD Ryzen AI 9 Pro HX 370. That combination of Initially showed real-time audio issues with very high DPC time in nvlddmkm. sys", you most likely will be for "wdf01000. sys (NVIDIA kernel driver). If a driver takes longer than usual to process, it may prevent other drivers from being processed in time (latency). Perform a clean boot (msconfig for Windows) to disable all non-Microsoft services, and use a tool like LatencyMon to identify driver-level DPC latency spikes, often caused by audio, network, or peripheral drivers. 02). The program reports both the highest single execution times and aggregated totals so intermittent but severe spikes become visible even if they’re rare. I have the same issue as you guys. • Increase in DPC latency observed in Latencymon [3952556] • Applying GeForce Experience Freestyle filters cause games to crash [4008945] Erick Sham 1 reaction · 2 comments Andri Andrian GeForce Community Indonesia 5y · Public #Driver#GameReady Download NVIDIA GeForce Game Ready 461. Many audio problems on a computer can be caused by high DPC latency. LatencyMon checks if a system running Windows is suitable for processing real-time audio and other tasks. 79 WHQL" Increase in DPC latency observed in Latencymon [3952556] " I am confident using an AMD GPU makes no difference to the default high DPC latency, and even though you will not be getting spikes for "nvlddmkm. Priority 3 is in-game graphical configuration. Although technically a business-oriented laptop, both graphics performance and performance-per-watt are The XPS series has gone through some bumps on the road, but the latest Panther Lake XPS 14 puts the family back on track to be a much easier recommendation than any recent predecessor. 2 Open Issues in Version 531.
