Windows 11 frame rate stuttering reported by some users with AMD CPUs

Some Windows 11 users are running into trouble with sporadic stuttering issues (accompanied with audio glitches), which according to reports are related to AMD processors and the necessary TPM security required by Microsoft’s newest operating system.

Specifically, on AMD PCs, there’s an implementation of TPM which is fTPM – meaning it’s integrated in firmware, rather than on a separate TPM module – and this is what folks who are affected believe is causing the issue, finding that when it’s turned off in the BIOS, the stuttering disappears.

Unfortunately, some people don’t have the option to turn off fTPM – that switch simply isn’t present in the BIOS – so they’re out of luck on that score. The other alternative solution appears to be installing a discrete TPM module, rather than relying on the firmware integrated functionality, and this also works to fix the issue – at least according to reports. Assuming you have the ability to install a separate TPM module in your PC.

As various reports detail, on Reddit, the Linus Tech Tips discussion boards and Lenovo’s forum to point out a few which Windows Latest flagged up (not to mention Microsoft’s feedback hub), the stuttering frame rates hit at random times and last for a few seconds in some cases – longer in others – and audio is garbled at the same time.

If that should occur, say, during a crucial moment of an online game you’re about to win, that’s going to be pretty frustrating (and doubtless it’ll be a serious annoyance as part of your everyday computing life, too).

Analysis: Losing TPM on Windows 11 is possible, but is it wise?

Note that this problem also occurs on Windows 10 PCs, the difference there being that enabling TPM isn’t part of the system requirements. So, while it’s fine to turn off fTPM on Windows 10 – assuming your BIOS allows for this as noted above – on Windows 11, that comes with its own potential problems.

Now, while it is possible to install Windows 11 and then turn off fTPM, that could cause issues with things like BitLocker drive encryption, or have other side-effects, like not being able to play some games (as Windows Latest observes, Valorant is one such game – and there will likely be more in the future). The biggie, of course, is that it could also interfere with receiving Windows updates, or so Microsoft says – though updates still appear to be delivered up to now.

Essentially, turning off fTPM is something of a minefield of possible collateral damage on Windows 11, and that’s why some of those who want to get around this stuttering glitch are downgrading to Windows 10.

This issue is hopefully something both Microsoft and AMD are putting their heads together to attempt to fix, so we can keep our fingers crossed that a proper resolution is delivered in the near future. If the glitches aren’t disrupting your computing experience too much, likely your best bet is to sit tight and hope for the timely delivery of a patch.

AMD’s Wraith coolers for Ryzen CPUs haven’t been upgraded – there are fakes out there

AMD’s Wraith Prism cooler, which comes bundled with some of its latest 3rd-gen Ryzen processors (and the Ryzen 7 2700X), is suffering from a surprising problem – namely fakes of the cooling solution are floating around.

Initially, it was thought that the respected RGB stock cooler had been upgraded by AMD, and just not announced yet, when photos of a very similar-looking model to the Wraith Prism emerged over at XFastest – except this one had six heat pipes, rather than the four that the standard model has.

However, AMD quickly took to Twitter to clarify that these cooling solutions with six heat pipes are illegitimate fakes designed to look like the Wraith Prism, and that they (obviously) have not been tested and validated by AMD.

Thermal trickery

So instead of speculation about how good this six pipe cooler might be, now the speculation is about what on earth is going on here. And indeed if this cooler is bundled with an AMD CPU, could there be something amiss with the chip itself?

Obviously something shady is happening, and it raises the prospect of an operation perhaps buying OEM chips, and pairing them with the fake cooler, to sell at full retail price (or possibly even fake chips – which we’ve seen in the past with Ryzen – with the fake cooler).

Although if this is the idea, quite why the cooler would be slightly different with the additional heat pipes, well, that’s anyone’s guess (in terms of not raising the profile of this counterfeiting).

Regardless, obviously you should be careful about this new counterfeit product. While it might be tempting to think that with the two extra heat pipes, this could be a better cooling solution than the official AMD-produced Wraith Prism, if it’s been made as a third-party knockoff, there’s every chance there could be all manner of things amiss in terms of the innards. Even if externally, it looks like a good copy of the original.
