Windows 11 scores varied wildly

[David (PassMark)]

More Win11 performance issues.

AMD discovered that certain Ryzen-powered Windows 11 and Windows 10 PCs experience intermittent performance stutters when running with fTPM (firmware TPM) enabled. The performance stutter is caused due to background memory transactions between Windows and the fTPM, to authenticate an action, as the fTPM serves the function of a hardware root of trust. Since the fTPM is part of the UEFI firmware that resides on the SPI flash EEPROM chip, the performance stutter is caused due to fTPM-related memory transactions with this chip.

TPM is "Trusted Platform Module" technology is designed to provide hardware-based, security-related functions. Usually this is a separate chip added to newer motherboards. fTPM performs the same security functions as a TPM, but it is embedded in the motherboard's firmware. A TPM of some sort is mandatory at the moment for Win11.

Firmware updates are planned for May 2022, but some motherboard vendors aren't very fast at releasing updates.

Seems there are more performance related Win11 patches that just arrived.

January 25, 2022—KB5008353
"Addresses a performance regression issue that occurs when you enable the update sequence number (USN) journal."

This should help improve disk write performance. They claim this was fixed before, but now it is fixed again.

I found one other baseline you uploaded from the same IP address: https://www.passmark.com/baselines/V...d=148754126352

Both baselines are not associated with any web user account, so My Baselines will not show any data.

For My Baselines to display your uploaded baselines, login to your Passmark account > My Services and make sure My Baselines service is enabled and show/request for a API key.
You will then need to enter the API key into PerformanceTest in either the Preferences or Upload baseline window and select 'Upload with API Key' to start associating uploaded baselines to your web user account.

I've noticed a drop in G2D after going from Win 10 (887.5) to the dev Win 11 (780.7). With the latest AMD driver, I'm at 823. Significantly, my Windows Interface score is in the 28% percentile, with a Radeon RX 5700 XT.

I'm not able to compare the G2D sub-tests without being able to recall them. I can only bring up my latest upload (Baseline ID# 1498844): PassMark Software - Display Baseline ID# 1498844

I don't know how to get any of the previous result breakdown web pages. My Baselines (passmark.com) shows no data, even though I've uploaded several. I can see them in Performance Test, but there's no breakdown of G2D there.

Is there a way to search for the web reports? I'd like to see the breakdown for Win 10/11 on my system.

[David (PassMark)]

So a bit of a mixed bag with those Win10/11 2D results. Some sub-test actually got slightly faster with your move to Win11.
But there were also some big drops of up to 40%. But no real obvious pattern.
I assume that you are using the same video card device driver version on Win10 and Win11?
So it seems likely Microsoft made some changes to the Desktop Manager software in the OS and GDI+ graphics layer and it has effected performance.

It is pretty clear at this point that Microsoft didn't do much performance testing before the release of Win11.

What hardware are you using (video card & CPU in particular)?

Attached windows 10 and windows 11 , PassMark 10 screen shot .
Which is having 2D mark details .

[David (PassMark)]

While not only related to Win11, it will probably be seen nearly exclusively on Win11 as it only occurs in new machines with 12th Gen Intel CPUs.

Intel's latest video card driver (for 12th Gen CPUs with integrated graphics) has a bug which crashes the DirectX10 test.

Manjunatha, Those are not the individual test results. So we can't see which sub-test was effected

Microsoft has released new details of the disk performance problems in Win11.

This was as part of this up coming Win11 patch release, November 22, 2021—KB5007262 (OS Build 22000.34 Preview)

"Addresses an issue that affects the performance of all disks (NVMe, SSD, hardisk) on Windows 11 by performing unnecessary actions each time a write operation occurs. This issue occurs only when the NTFS USN journal is enabled. Note, the USN journal is always enabled on the C: disk."

The USN journal is a NTFS metafile (so always hidden from the user unless you are using forensic tools), called, $Extend\$UsnJrnl.
The journal file is used to track file changes, and this is in turn used by the file backup function to determine which files have been created and modified in order to back them up.

It isn't known what the "unnecessary actions" actions they refer to are. But it amounts to extra unwanted background disk activity.

[David (PassMark)]

Thanks for the Win11 results. Do you have the Win10 results to compare with?

[Manjunatha]

pls find attachment of windows 11 Passmark test result

[David (PassMark)]

They are not the individual test results. So we can't see which sub-test was effected. Ideally you want to run each test several times as well just to make sure it wasn't just a one off result.

2D Graphics Mark for windows 10 ( 21h2 ) = 704.2
2D Graphics Mark for windows 11 = 509.2
