Windows 10: QueryPerformanceFrequency returns 10mhz on Windows 10 Build 1809+, causing performance...

It appear something has happended to the timer subsystem resolution on Windows 10 starting from Build 1809.


QueryPerformanceFrequency() returns 10mhz (10ms) which is causing the GUI et al to have latency. DPC latency is also elevated post 1809 installation. This happens on multiple, different motherboards (AMD, Intel) as well as various configurations.


Video editing software is no longer able to render things as quickly as it used to, on post 1809.

The hilarious part is, my Mac Mini with less ram, CPU and video card power is able to perform the rendering faster than Windows 10 (1809). It can also boot up faster than anything Windows 10 servers.


Some issues with 1809:


- Logging into windows takes 8-12 seconds before I get into the desktop. This is on a m.2 SSD, with a threadripper 1950x / 128G of memory. (1809)

- Removing 1809 allowed it to boot into the desktop around ~2 seconds. (Tested on 4 different machines, AMD, intel, etc)

- 1809+ has caused additional lag when clicking, launching and performing any kind of tasks.


Notes:


- Removing 1809 causes QueryPerformanceFrequency() to return ~3mhz, which is the TSC. Performance returns to it's snappy self.

- Forcing the use of the slow, awful, HPET makes things better, for a time, until multiple one-shot timers are running and then the boxes crawl to a halt.

What timer subsystem returns 10mhz? The TSC doesn't, PIT doesn't, APIC doesn't, ACPI doesn't, HPET may do it with a divisor.


TBH, If this doesn't get solved soon, I'll just move the rest of my stuff over to Apple Products and never used Microsoft products for enterprise again.

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Stuck in Returning to previous build

Hi Paul,

Thank you for posting in Community.

Before we proceed, I would like you to provide the information stated below:

1. What task where you performing when you receive the Black screen?

2. Where you installing any software?

3. Can you access your desktop screen?

If not, then I would suggest that you perform Power Drain and check if you can return back to your desktop screen. To do so follow the steps below:

• Unplug the charger and remove the battery of your laptop, if using a desktop remove the power cord.
• Press and hold the Power button for 30sec
• Plug the charger/power cord and restart system.

I would also suggest that you refer to the Microsoft Article Troubleshoot blue screen errors
provided in the link below

Your reply is very important to ensure a proper resolution. Please get back to us with the above information to assist you accordingly.
