Yep. Latest BIOS, drivers, etc.. AFAIK, I'm all up-to-date everywhere. The problem I'm seeing is that certain programs (mostly Calibre ebook manager and its tools) will not necessarily visibly start when I click on them. But, if I look in Task Manager, they'll be there using a bit more than 10% of the CPU. When that happens, if I continue launching copies, those'll start, but each additional copy uses about 10% more of the CPU. At first, I thought this was a problem with Windows Security (Defender). So, I put in exceptions for the program's folders. It still happens.
This started with my old installation of Windows 11 21H2. But, it continued through 22H2 (and a new install, at that). I think the issue started about the time I upgraded the chipset drivers to the latest version. But, I'm not sure. Another possibility is Adrenalin, since I also updated that at the same time.
I just tried turning off GPU acceleration in QT Webengine (which Calibre uses). So, I'll give it a bit more time to see if that fixes anything. Oddly, this version of Adrenalin is supposed to have fixed GPU acceleration in things like Chrome.
