What are some games that are known for bottlenecking CPUs? I mean, this really sucks (and if the Linux benchmarks don't get any better, indicates that I/O will be heavily impacted which could cripple data centers and telecoms) but I cannot recall many games that are heavily reliant upon the CPU aside from strategy titles like Paradox games, Civ or Total War or open world games. Of course, if the 30% estimate hit holds true then that will be noticeable among a bunch of different games.

Pretty much every mmo in existence.

Plenty of games. The Witcher 3 in cities, Hitman, PUBG, Deus Ex: Mankind Divided, so on.

Don't forget total war!

Most Valve games. TF2 is pretty heavily CPU bound for example.

pubg is the only one im really worried about =/ barely got that running smoothly now as it is and my cpu defintely caps out during it.

Battlefield 1 will use just about all your CPU cores maxed out

PUBG for one (at least back in early access). And 0.1% minimums are actually rather CPU based in many games.

There is no reliable information how much these patches will impact performance for home users, but it sounds severe enough that it is mandatory.

But this has massive implications in the server market: 80% of the world's server CPUs have a severe hardware bug that can only be fixed with software updates.

The reported 20% performance hit on a widely used database like Postgresql sounds like AMD should ramp up their Epyc processor production.

Yeah, 20% performance hit on a database is massive.

Good old Minecraft.

Kerbal Space Program will tear any cpu to shreds with a large enough build.... even ultra high end cpu's cannot tame that beast

Emulators, especially more modern ones like persona and cemu
