Depends heavily on the GPU and resolution. Maybe you selected 640x480? More frames/seconds, more timer calls.

The game test is here to see the average frame time and therefor stuttering.

I want to share my results with Zen 3:
timerbench_256558.png
Much better synthetic throughput and much less frametime spike with it off.

But honestly I don't notice much difference playing games, except emulators, Xenia(the Xbox 360 emulator)runs much worse with it on:

VS. off:

Apparently, my HPET was already off.
It's very possible that I disabled it some previous attempt at tuning my PC performance.

Although, device manager did not reflect this "High Precision timer" was enabled here, and I don't believe I disabled it in BIOS simply because my bios on this ASUS machine is absolute garbage. It's got none of the things most gaming BIOS would have. Probably the worst part about the 2021 ROG G15 Zephyrus (labeled a gaming laptop) is it's crappy BIOS.

... but your program's GUI was displaying the "Enable HPET" button the first time that I ran the software. I ran a test, it said my HPET was 10.0 Mhz. Things seemed to work, I could see test results.

Then I pressed the button "Enable HPET" and my PC rebooted.
When I came back to TimerBench, now there is a button "Disable HPET" and the weird part is, the tests cannot be run anymore. There is a greyed-out button that just says "Initializing" and it never changes.

So apparently HPET was previously disabled on my machine and I just enabled it, and it seems when HPET is enabled on my machine, your TimerBench does not run. I'll just turn this back off now, as I'm pretty sure I don't want it enabled.

Machine specs:
ASUS G15 Zephyrus
CPU: Ryzen 9 4900HS
RAM: 16GB DDR4
GPU: RTX2060 Max-Q
vRAM: 6GB GDDR6

In der neuesten mesa Version gab es anscheinend auch Probleme mit HPET. Schade, dass man es heute im vielen UEFIs nicht mehr einfach deaktivieren kann.

Yes. More calls means less latency per call. Less latency means your CPU and GPU will be less bottlenecked.
