Quoting: Power-Metal-GamesnVidia GPUs are switching performance levels all the time like expected. I thought that with CPUs everything was the same...

But they do! Their performance levels are called Mhz, not governer.

Quoting: Power-Metal-GamesI tested it, and it's never switching to „performance“ without command and I find this stupid.

That's how these settings are supposed to work, though: You decide about the governor (if you actually know about it), and the governor decides abotu you CPU speed. It doesn't magically switch governers, it magically switches speed (in the limits of what the governor is supposed to archive).

Quoting: Power-Metal-GamesDoes this mean that all the benchmarks of games were actually incorrect? I mean Windows vs Ubuntu (or Linux in general..)?

:-( I fear, rerunning some might be interesting...

*edit* If you do, don't forget to search for other possible optimizations in advance, like maybe this one: https://www.gamingonlinux.com/articles/you-will-want-to-force-your-cpu-into-high-performance-mode-for-vulkan-games-on-linux.9369/comment_id=89164

Feel free to register unreadablecrap.com and publish there all the documentation you can find in an unreadable tiny font with a choice of colors that makes the readers blind within five minutes.

why? they already did that with this plaintext.

The display of plain text is up to your browser/you. Some Strg-+ makes it already look nicer here.

Wow! Didn't expect that much non-exaltation! Seems I need to rebuy it and play again just to see if I remember all wrong. ;)

Quoting: buenaventuraHow do you do this? Entering bios with F2 during boot, I see no option to turn Turbo on/off. Perhaps it is not supported by my "AMD A8-6410 with Radeon R5 Graphics (up to 2.4ghz)". However, in bios it says that my computer has only 2000mhz cpu freq, so clearly the CPU is not turboin :P

It might be throttling down some GHz as it doesn't need them in BIOS.

Quoting: HailToTheGrailYou could give setuid a try. Make a shell script as root, and then: chmod u+s script.sh
You should be able to run it as a user with it's owner rights, which are root.

Of course, this gives root access to somebody able to login as you (and edit the script).
Maybe giving suid root to the called executables would make a smaller security hole.

Quoting: M@GOidFor a more easy way to change the settings, install the package "indicator-cpufreq"("sudo apt install indicator-cpufreq" for those of you in Ubuntu). It will show a icon in your taskbar were with 2 mouse clicks you can change to the Performance governor and back. I use it for both AMD and Intel CPUs for years and it works great, for any DE.

Sounds good, thanks!

Uh, powersave isn't the default governor, at least it shouldn't be. powersave will run your CPU at the minimum freq.
You want ondemand.

I'm not 100% sure, but AFAIK, I found powersave and performance the only states implemented for my i3570K when I looked.

The reality is that such control algorithms are CPU specific, the notion of a generic "for all cpus" governors is just outright flawed; hardware behavior is key to the algorithm in the first place....

Quoting: buenaventuraHmm, does this setting the CPU governor to performance impact games otherwise you think (like, with OpenGL on a weak CPU?).

I have a AMD quadcore A8-6410 ("up to 2.4 ghz) on my laptop, and I struggle to play Shadow Tactics (and other unity games) on lowest settings, sometimes I think my CPU is at fault as much as my GPU. top reports around 250% CPU usage (which means 2.5 cores used I guess) for Shadow Tactics. Is it possible to increase that usage, you think?

It's worth a try. I had to do it - strange enough - for Limbo to work in the correct speed. :)
