Hi,

I just spend a weak building my pc where a saved a long time for.

Everything works as in is functional. But there are a lot of frane drops in the ui, let alone gaming. The cursor doesn't move mooth over the screen. And when I play audio thrue USB, optical or AUX it pops and cracks.

PC:
Ryzen 9 5900x
Aurus x570 master
64gb ram
980 pro sdd
RTX 3080ti aurus extreme
1000 watt corsair gold RM
....

I installed Windows 11 becouse I have already used it on my laptop, I like it more then Windows 10, and I don't like upgrading so I thout a clean install from the get go was the best option.
I ran latencymon and saw this:

I have 2 sceenshots of the overview one with nvidea as main couse and one with acpi

Then I also added a screenschot of the drivers and CPU tab.

And a screanshot inside system information --> Hardware --> conflicts/sharing
system-info-harware-conflicts-and-sharing-png.6456


All of this looks out of normal when I conpare it to my previous pc or my laptop.

I have tryed latencyfix software (and everything else in this thread Fix High DPC Latency on Windows 11/10)
tryed disbling network interfaces in divice menager
Tryed DDU with audio and video driver, installed the autio driver for my motherboard and video driver from nvidea without gforce exerience.
tryed different bios (mobo has 2)
installed all updates and also chipset driver
But now I dont know anymore what to do.

Any recomendations?

Thanks in advance for the help, it is much appricated!!

Welcome to the Forum


Both the first two screenshots indicate that your latency problem are due to CPU throttling. CPU throttling is where the computer restricts the CPU clock speeds, and runs the CPU at a lower frequency. It is likely that is happening due to high temperatures inside the computer. Your computers performance will be affected, but the computer can maintain lower temperatures at the cost of lower performance.

To investigate, download and run Open Hardware Monitor and check your computer's temperature sensor readings

Hi,

thx 4 the replay.
Temperatures are fine, dark rock pro 4 keeps cpu beleof 55 on idle and below 75 on full load. I have an all core 'overclock' set so the clockspeed odes not flutuate, and all power seving and other relatad settings are of.

I now have clean installed win10 on a seperate ssd and everything looks fine after installing drivers.
I also installed win11 after that and it looks also fine.
So I will just try clean installing my main drive and hope for the best.

If the problem comes back I will add a new post

but up until now everything works and I have no explenation why.
