$ grep . /sys/devices/system/cpu/vulnerabilities/* grep: /sys/devices/system/cpu/vulnerabilities/*: No such file or directoryA ten skript je na k***t, pretoze nezistuje skutocny stav (ne)fungovania exploitov.
Takže bude chvíli trvat, než to někam probublá.Nicmene zda se ze nektere "enterprise" distribuce maji vazny problem s rychlosti probublavani, jak poznamenava GKH.

že enterprise distra mají občas skluz, než něco otestujouTo bezesporu. Otazkou je jak dlouho jim to trva a zdali jsou vubec schopni opravy v rozumne dobe backportovat.
údajně se to blíží k nule.Tak "udajne" mozna ano, prakticky nikoliv, viz zde.
So most games are not impacted, because there are not many syscalls / user<>kernel commands going on. But if Denuvo (I'm not too deep into that stuff, just a speculation about my AFAIK status) adds some layers between the game, the OS and adds some virtual machine stuff ... well, that needs many syscalls. So that might be a good reason, why some games have a way bigger impact then others. Especially on older hardware.
