Microsoft warns of KB4482887 game performance issues

[HEXUS]

Retpoline update: Graphics and mouse slowdowns evident in Destiny 2 and others.

When you apply a little bit of thought, it can make sense, but if you step back and squint..
a patch to improve performance, decreases performance. That's Microsoft(R) Magic™.

[Kanoe]

So if it causes an issue you can uninstall it to regain the performance detriment of having to mitigate Spectre and Meltdown, cool.

This update broke my PC.

Again.

I'm tired of updates which break my PC in such a spectacular way that it takes me hours to fix it. I even made it so I could bring up the boot menu to get into safe mode (they removed this from Windows 10) to allow me to uninstall the updates easier.... and they appear to have removed that now as well. So this time all I get is a blank screen once I've booted and I can't do anything to get into safe mode. So yet again I'm back to turning it off mid boot 3 times to bring up the rescue menu - that's fine, I'll just power down a booting PC repeatedly. I can't see that going wrong in any way shape or form.

What is with these people?

The problem is the patch is not universal. If you do not have any Spectre uCode mitigations enabled the patch does nothing. If you have Skylake or higher it is not applied / does not have benefit due to the differences in the RSB.

The real issue is going to hit in 19H1, as uCode for Spectre v2 is included in the base install mcupdateGenuineIntel.dll (you will have to use the .dll rename 'hack').

As I understand if you have Broadwell or earlier and hardware uCode you will have Retpoline enabled - according to MS AI, this is on 1809 with this KB.

So it won't affect everyone equally.

Hats off to MS they're really screwing this up.

Is it entirely fair to blame Microsoft when it's all to do with Intel chasing performance over security?

Not really no, but currently its cool to hate Microsoft, Nvidia and Apple, so people will

We'd need to look at how it's effected other operating systems that use Intel CPUs, not something i care to look into if I'm honest as Microsoft & Intel will be history to me before the year is out.

Don't really think you can compare with other operating systems though, Windows doesn't slow down as much as Linux as it's already slow

... but then I'm saying that as basically a disinterested Linux on Ryzen user.

Yes. The performance hit is a product of their "update" and as a result plenty of people have been affected. Yes, someone else created the primary issue but they are the ones which did not test their update properly. It wouldn't be as much of an issue if it weren't mandatory. I can not completely opt out of this update, even if I accept the risk and so on that comes with that decision. It's a matter of "we know best and you know nothing so we'll do as we like with your PC, regardless of the negative effects".

I have had to uninstall the last lot of updates as they borked my PC beyond use. There will come a time where MS forces these updates on me and if they haven't fixed the problems I'll be left with a PC that can not use Windows 10 due to modifications MS have made o the product I have bought. I therefore can not use the service I have paid for. Is it a result of MS's lack of testing or is there a part in my PC that W10 doesn't like? Who cares? It should not cause so many issues and every other month result in a PC that requires hours to fix.

Just give me control over my updates and we'll be all good. But no. How about I accept the Meltdown and Spectre risk and choose not to update? A choice? No, they know better. And I'm the one who spends hours fixing things as a result.

Intel's own engineers didn't discover the original exploit, but a 3rd party examining their documentation.
At what point is the fix causing issues.
If its on a hardware level, then is it really any surprise Microsoft might not know its impact sufficiently if Intel's own engineers obviously don't know their own hardware well enough.
If it is on a software level only, then yes Microsoft should have been aware of this.

windows 10 pro + semi-anuual update channel = what updates?
