It might be placebo but I find that using ISLC to set the system timer to 0.5ms
feels so much better on my ryzen machine with HPET ON in BIOS(OFF in Windows strictly with disabledynamicticks YES, useplatformtick YES).
I thought applying useplatformtick tweak forces using HPET if it's enabled in BIOS.

useplatformCLOCK does that.
And if using this 'true' or enabled, and HPET is forced off in BIOS it will use ACPI TCO Timer.
Anyhow, whats the most ideal DPC/ISR latency under these Ryzen systems
Both my Intel desktop and laptop are around 1~20us

Ok, I did "bcdedit /set useplatformclock true" and played few CS:GO matches, it seems mouse movement improved.
Now need to test "bcdedit /set useplatformtick yes".

I am about to build a new machine after 10 years on my Intel 2500k oc'd to 4.4 on stock volts.
I came across this thread because I was actually thinking about going the AMD route with the new 5900x coming out next month.
They mentioned that the single threaded performance of that chip is significantly faster than the 3900x.
Should I be rethinking the AMD route and stick with Intel?
This machine will be a work/editing/gaming pc and now that I am working from home I really feel the need to build my next machine. I play fps pretty competitively and being that historically I build a machine every 6-10 years, I want to make sure that I am getting the best possible CPU ( and lowest latency for gaming )

If your audio breaks with those two timer edits, e.g. every game I played at one point or another the audio would completely cut out in-game, force HPET with bcdedit /set useplatformclock true. For me that fixed the audio issues. Your experience might differ. To restore the default: bcdedit /deletevalue useplatformclock.
I noticed that I have DPC spikes to 1200-1300 during the game if I set "useplatform
tick yes", but if I use "useplatform
clock true" instead (not together!) DPC spikes to 300-400 max.

My Program disabled DWM in WIndows 10 up until v2009, as the time of writing. Its still not released yet but it will be soon. Search for GPU Booster or n1kobg.

Wait for reviews. I will, however, bet the 5K series will be a beast of a chip.
Tells nothing about the latency so yeah, reviews is a must.

HPET has both a counter and timers.
UsePlatformTick invokes an HPET timer as the system timer or in the event there is no HPET then uses the RTC and uses interrupts.
UsePlatformClock invokes the HPET counter as the performance counter (QPC) or in the event there is no HPET then uses ACPI PM Timer as a counter, the PM Timer isn't suitable as a system timer. No interrupts, just a count.
