16" M1 Max Macbook Pro high GPU usage (20%-100%) at random during routine activity This started last Mon or Tue after I upgraded to Monterey 12.6.2. I also applied the Parallels 18.1.1 upgrade. I run two Windows11 VMs. My usual workload is Excel. Large spreadsheets, 25-85MB in binary format. The M1 MPB is great for this work. It cut my computation time from 7-10 minutes to less than a minute for the smaller file. I can scroll the screen and do other graphics intensive things without a blink. I love it. After the upgrades, all of a sudden I get slow screen response. This give me flashbacks to running these jobs on my 2018 MBP. The high GPU use happens randomly. I check the Win11 Taskmanger, it shows excessively high GPU use. What is going on? Most internet research shows two things: I am using the wrong resource monitor. The GPU use is not real in which ever monitor you are using. Wrong answer, the resource monitors match the sluggish screen response. I am looking at three different monitors. Task Manager and Process Explorer in Windows. And, Activity Monitor in Monterey. They all parallel each other in their reporting. I really do not need a resource monitor to see/know this happening. Upgrade my video drivers. Parallels does not use those kind of (hardware) video drivers. But, I did roll back to Parallels 18.0.2, just in the case 18.1.1 had something in it. This is not the problem. This leaves three areas left to explore: It is a macOS issue with the 12.6.2 upgrade? It is a hardware issue with the MPB M1 Max? It is a Windows11 issue? macOS 12.6.2 issue?? I would love to rollback to 12.6.0 or 12.6.1. See if that eliminates the cause. Unfortunately, I do not have a copy of either if those installers. This give me the only choice of upgrading to Ventura 13.1. I can rollback to 12.6.2, as I have a copy of that installer. No, I do not see this problem while running programs on the Mac host. My work is done in Excel for Windows. Still could be a problem in the 12.6.2 release that "breaks" something in Parallels 18.x and/or Win11 for ARM64; without affecting other Mac applications. Hardware issue?? I do not think so, I think I would see this popping up with Mac applications too. Windows11 issue?? This is a Beta of Win11 for ARM64, after all. Some problems are expected. Some problems were experienced in August. I would like to roll this back too. Alas, Apple and Microsoft, both sort of force you to the latest version. And, make it difficult to get the older versions. That gives me an idea . . . I will look in my backups and see if I have an older PVM. While typing this up, the GPU went wild for about 5 minutes. These excursions run 5-15 minutes. AND, affect both VMs at the same time. Here is what TaskManager looks like during an excursion. It was quite a trick to snag this while the GPU was going crazy. You thoughts . . .

Hi Alanastro,

I believe we need to proceed with an EtreCheck report. EtreCheck is a useful app to diagnose issues, both hardware and software. It is trusted by many users. Please follow the steps outlined below:

Go to the Mac App Store and search for "EtreCheck."
Download it. It is a free and trusted app; as it is on the Mac App Store, and only trusted apps can be submitted.
Run the report, and put it in a post, as seen here - https://discussions.apple.com/docs/DOC-250000211
If it asks for Full Disk Access, follow the prompts to enable it.

Cheers,

Jack
