Presentmon 2.3.1 comes with new GPU telemetry features; Check out the details

In the new version it made available from Presentmon, Intel added new telemetry metrics, which include effective frequency, voltage regulator temperatures and total power of the plate.

Version 2.3.1 also brings new SPF overlap indicators and overlap can now disable alpha mixingimproving performance during measurement.

Intel also updated Presentmon to allow the execution of the software without the need for system administrator privileges. The update aims to circumvent the problem of Windows Defender accuse the software as a virus by trying to access hardware information.

The new version can be downloaded directly from the official link.

New FPS and Telemetry features

The update brought three new FPS overlap indicators. The goal is to provide a clearer view of frame delivery behavior, especially in scenarios involving frame generation.

Now, users have access to FPS Display (The frame rate displayed on the screen), FPS Presents (which measures the frequency with which the tables are presented to the GPU) and FPS App (which is similar to FPS Present, but behaves differently when the generation of frames is enabled).

The FPS-PRESENTS measures how often the frames are presented to the GPU, while the FPS-Display captures the rate at which the frames are actually displayed on the screen. The FPS-APP usually corresponds to FPS-PRESTS except in frame generation scenarios.

With the update, they were also added the following GPU telemetry metrics (Currently supported by the GPUS Intel Arc Battlemage):

• Effective GPU frequency
• GPU voltage regulator temperature
• Effective GPU memory width
• GPU Overtension Percentage
• GPU temperature percentage
• GPU power percentage
• GPU fan speed percentage
• GPU plate power (total plate power)

Other news

The update reintroduced support for several CSV timing metrics, including msbetweenpresents, msbetweendisplaychange, msinpresent, msrenderpresentlycy and msoutidoplayed. Msbetwensimulationstart and mspclatecy have also been included, but are currently disabled until support for underlying events is enabled.

Version 2.3.1 also increased the size of the standard Presentmon circular buffer to 2048allowing support for higher FPS applications. In addition, a command line parameter has been added to manually configure the buffer size.

And, with the addition of the click option to disable the alpha mixing of overlay, there was the reduction of the impact of overlap on the present time target. However, there are some exceptions for this reduction.

General News:

• Added presentmon console application support for hybrid presentation detection
• Compatibility with the binary version of the stabilized Presentmon API, implementing Presentmonapi.dll side by side with the service and migrating to a dynamic loading model.
• Added loader.dll + static import.Lib to facilitate the discovery and resolution of endpoints from API Presentmon.
• Added ETL cut utility to cut ETL files to a Timestamp interval and remove unnecessary event types (source only, currently without binary distribution provided).

Updates on Experimental:

• Added the ability to inject executable code into the destination process to make a flash draw in the game whenever the mouse is clicked. The function is intended for use in conjunction with specialized optical measurement instruments.

Security and Life Cycle Updates:

• Multiprocess architecture dismissed to allow presentmon to be executed without administrator privileges.
• Improved security, ensuring that the CHROMIUM user interface frontand is performed with reduced integrity, even when Presentmon is performed with high integrity.
• Updated Vue.Js 2 updated border, as it has passed the end of its life and without support.

WinRing0 vs Microsoft

Although most users are more interested in GPU telemetry issues, The main update for some enthusiasts involves solving the problem with the Winring0 Library.

For those who are unaware, it is an open source driver that was largely Used by developers who could not develop and certify their hardware control tools, such as RGB LEDs and fans LEDs.

That is, for small teams wishing to distribute software to monitor or control any hardware from a PC, Winring0 was a great option. However, it was also widely used by large companies.

The problem is that The Creator himself announced the end of development in February 2010. At the time, he stated that “winring0 is essentially a library that should not exist” as a result of several problems that occurred after its creation.

It turns out that drivers are a great way to hide viruses. Therefore, Microsoft requires installation certificates for Windows. The goal is for drivers on a site not different from what is announced.

Certificates are guaranteed by a reliable “certifying authority” (AC) that verifies:

• If the file, or the file set, is signed.
• If the signatory is reliable.
• If the certifying authority that authenticated the signatory is reliable.
• If the file set was not changed after its publication.

Problem history

To get an idea of ​​the problem, in 2019, HP has been involved in problems with including pre-installed Winring0 on its HP Touchpoint Analytics service. And this has become a major safety concern for one of the largest original equipment manufacturers (OEMs).

By 2023, Steelfox malware took advantage of a vulnerability. Basically, after getting the administrator rights, The virus created a service that performed Winring0.sys internally and guaranteed local access permissions of the highest level. Even the virus had greater access than the administrator.

So it was not only with Windows to defend that Winring0 and similar drivers have encountered problems. Software like Easy Anti-Cheat also tend to signal it due to its ability to read and override memory.

That is, as much as it is a trusted software that the user has downloaded, using winring, the risk exists. In short, in this case one cannot blame Microsoft for the inconvenience.

Small, but a victory

Intel is in need of a victory and, however small, the new Presentmon update is a victory for the company. With the update, the company has shown that it can reinforce system safety without harming telemetry software.

However, the situation is still concern. Especially with rival AMD winning the first and second place on the list of the most powerful supercomputers in the world.

Recently, the company’s actions have reached the historic low of the last 16 years. Despite the negative result, Jim Keller said the company is worth $ 1 trillion. It remains for delivering results that are compatible with the value.
