Please tell me you did not apply meltdown and spectre patch.
If you did then you degraded your performance by atleast 2 generations.

Ivy bridge here and windows automatically updated those vulnerabilities, i lost minimum 15 fps on most games.
Unpatched it and now everything is fine.

You really think someone is out to get you if you don't patch these vulnerabilities.

>> No.68853914

>>68853897

the risks are that if you have open ports on your router/modem then you'll get fucked by an intrusion, as no operating system withstands a spectre/meltdown attack

but it typically need to come from inside your local network, as updated firewalls can easily deflect most of these attacks.

tl;dr don't download suspicious stuff and don't host public servers and you're fine

This whole shit gets very confusing.
Everybody deployed patches to mitigate/secure against those.
Windows did, Firefox did, Chrome did. I'm really wondering if the CPU microcode update is really necessary at this point, especially considering the likelihood of such an attack ever happening to you. Besides, iirc, the vulnerability doesn't make execution of code possible.

Definitely this, all those getting worried are tech illiterates who know nothing about programming.
All major browsers are patched and only way you infect is if you download some dumb shit.
And attacker even has to know that you are vulnerable to even care about attacking you.

You can simply downgrade the microcode of your BIOS and delete two DLL files to stop windows aplying microcode updates on runtime.

One reason is because before Haswell, there is no INVPCID instruction, therefore pre-Haswell CPUs become slower when the patch is applied. Microsoft also refused to use INVPCID optimizations on older Windows except Windows 10, so even if you are running Coffee Lake with Windows 7/8.1 it's slower. INVPCID is related to the Meltdown patch, not spectre. The patch for Spectre is what slowed Haswell down though.

Basically, these patches highly impact performance on the following architectures:

Meltdown: Nehalem(Partial), Sandy Bridge, Ivy Bridge

Spectre: Nehalem(Partial), Sandy Bridge, Ivy Bridge, Haswell, Broadwell


The one advantage of pre-Skylake processors is that you can simply use Retpoline on linux and you are patched for spectre. However, on skylake processors, since the BTB(predictor thinggy) is too aggressively utilized, you need IBPB as well.

Basically, on windows you are using IBRS, STIBP and IBPB for Spectre which are microcode instructions. They highly impact performance in many scenarios.

In Linux, you either use Retpoline(software based) for Spectre or Retpoline+IBPB for Spectre. The performance impact can be greatly reduced.

Another reason to switch to linux on your older machines.

Also, AFAIK most current silicon still doesn't have built in Meltdown/Spectre mitigations built in yet. Maybe the 9000 series K and X processors have it.

>>68853605
The Spectre patch is installed together with the Meltdown patch, but remains disabled until a microcode update. If your Microcode is updated via a BIOS update(Microcode is embedded in the BIOS), or via Windows update (This microcode exists as mcupdate_genuineintel.dll and is loaded from the OS not at boot), then the Spectre patch becomes activated.

I'm confused now.

There's a way to upgrade the BIOS for my mobo by updating the microcode manually for these patches. If you have an up to date microcode, is it any different than having these protections enabled on Windows without the microcode?

I mean, I did that manual patching being a little bit paranoid but to be quite fucking honest I haven't had anything ruin my shit for generations and I haven't even used some antivirus/antimalware for a long time. So would it be just fine to disable those protections or does it require a downgrade if you want to bring performance back? That's what I don't get. I get slower speeds on my SSD from what I've seen so far.
