    Até pode nem ter nada a ver, mas porra...isso fica tão mal.

    Understanding the performance impact of Spectre and Meltdown mitigations on Windows Systems
    ...
    Here is the summary of what we have found so far:

    -With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.
    -With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.
    -With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.
    -Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.

    For context, on newer CPUs such as on Skylake and beyond, Intel has refined the instructions used to disable branch speculation to be more specific to indirect branches, reducing the overall performance penalty of the Spectre mitigation. Older versions of Windows have a larger performance impact because Windows 7 and Windows 8 have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel. We will publish data on benchmark performance in the weeks ahead.

    Your Antivirus May Cut Off Microsoft Security Patches

    It seems as though a lot of antivirus packages have been causing a lot of headaches for Microsoft Windows users and Microsoft support lately, in that with the Spectre and Meltdown being pushed out, some of those antivirus packages put the OS into a BSOD reboot state.

    Future Windows updates to be blocked if your anti-virus isn't set properly

    In an interesting new development, some anti-virus applications may be incompatible with the patches Microsoft has pushed in order to mitigate the Meltdown and Spectre vulnerabilities that were recently revealed. In a rather heavy-handed tactic in order to ensure compliance by anti-virus vendors, Microsoft will hold their users' PCs hostage, and block all future security updates until a specific registry setting is changed.

    Bem, acabaram as férias e a semana da papança, lol.

    Só jogo, não tenho nada de importante no PC, mas uso e abuso do meu homebanking, devo preocupar-me, ou forget about it?

    Boas!

    Preocupa-te em aplicar os patches de segurança. De resto, que podes fazer?

    Intel's fix for Meltdown and Spectre had a bug of its own

    https://www.neowin.net/news/intels-f...bug-of-its-own
    Here’s how, and why, the Spectre and Meltdown patches will hurt performance
    Now that microcode and patches are starting to ship, a clearer picture is emerging.

    Spectre and Meltdown patches causing trouble as realistic attacks get closer
    Driver incompatibilities and microcode problems are both being reported.
    ...
    However, anti-virus companies aren't the only people to write ill-behaved drivers. ZDNet reports that a wide range of industrial systems is experiencing driver incompatibilities with the Meltdown fixes, with current guidance being to hold off on deploying the updates until the problems are resolved.
    The Spectre updates are also proving problematic. Microsoft withdrew the patch for AMD systems last week after some machines were left unable to boot. The company has resumed distribution of the patch to most AMD systems, but some older machines are still being excluded.

    First Hybrid Intel-AMD Chip Benchmarks Show Vega M Obliterating Intel UHD and MX 150 Graphics

    HotHardware has gotten to run some benchmarks on the first Intel-AMD hybrid chip with the Dell XPS 15 convertible. The XPS 15 2-In-1 tested was configured with a Core i7-8705G processor (3.1GHz base, 4.1GHz boost), the Radeon RX Vega M GL graphics engine with 4GB of HBM2, 16GB of DDR4 memory, and an ultra-fast NVMe SSD.

    Running at 1920x1080 resolution, the XPS 15 2-in-1 was able to maintain an average frame rate of nearly 35 frames per second with High image quality settings dialed in, 29.69 on Very High in the video. Intel's HD 620U could only manage 8 FPS on medium settings, and could not run the game on high as it would run out of frame buffer memory. An 8th generation Core processor paired with an NVIDIA MX 150 GPU was able to put up an average frame rate of around 23 frames per second in the same benchmark at High IQ settings.
