![]() However, with testing across 2 systems (my old Q6600 and my current 8700k builds with various GPUs) I've clearly found that HPET has severely degraded gaming performance on my Intel systems. ![]() Lower max ISR and DPC latency by definition is an indicator of how quickly your system can respond to any given interrupt and execute the driver routine and/or other code.Ĭlearly, if any of your input devices or GPU processing latency is unaffected in this regard, then technically, you may not see reduced input lag. Sorry, but generally speaking, that's incorrect. ![]() On my Ryzen PC with Windows 10 v2004 I have HPET enabled in BIOS and "useplatformclock true" in OS because it gives me better mouse input (less input-lag), and honestly I couldn't care less if this tweak raises DPC latency from 30 to 50. "Better DPC latency" doesn't necessary mean "better input lag". , 14:08However, as he mentions, do not enable HPET if you want low latency.
