    Stupid question: why are people looking to OC Retroarch when RA already has an overclock main menu setting? Is it for GPU purposes in 3D-based games (N64, PSX, etc)?

    Thanks!

    Thank you, had no idea. Are there a generally accepted GPU/MEM/CPU settings for PSX/N64 games?

    Last I checked most PSX games were ok at max Retroarch CPU overclock settings; though I could see being able to up GPU to lower the load on CPU...maybe?

    I was hoping to get the answer too or it just for Switch games.

    GPU isn't relevant for PSX-Rearmed, its all software rendering.

    I'm skeptical of a significant benefits from underclocking the GPU when it's not being pushed, it seems to idle quite well as is. You can definitely gain from dropping unneeded CPU clocks though.

    what about on MAME cores in RA? i copied and pasted from sys-clk pre-made configurations in atmo/sysclk/conf.ini

    Only dreamcast, N64, PSP, and now I guess Saturn have Switch cores that use 3D acceleration. Everything else is pure software and relies mainly on the CPU, which can be changed within Retroarch. Unless you want to run an intense shader there's not much gain to be had clocking the GPU for arcade games.

    Noob questions,

    1. Does handheld_charging override both handheld_charging_usb and handheld_charging_official? (assuming it can't reach higher clocks than the max)
    2. If you set a higher value than the max for certain mode, is the OC pushed to the actual max of said mode or does it get disabled?

    Reading the github itself...
    2. This one I cannot answer, but since there are max values, I'd have to assume the closest working value is selected. If you want to disable OC'ing for something, you can either put a '0' or nothing.

    2. It’ll get pushed to the max clocks that mode supports (ex. If you set handheld to 921mhz GPU, it’ll run at 460mhz)

    Thank you. Does the sys-clk overclocking apply to PSPPPP as well? Or just RA?

    huh, I was under the impression that the official charger was required for some/most/all handheld overclocking. Is that incorrect? Thanks!

    I used sys-clk in combination with Atmosphere / Hekate and it doesn't seem to work. I see no graphical improvements with max overclocked specs in handheld mode with official charger (with DOOM and The Witcher 3). I have set the config file correctly. What could that be due to?

    Not exactly what you are looking for but the latest hbmenu has a temperature indicator. Quite fast to check if you launch it as an applet.
    I have it compiled here:

    You don't need that, sys-clk has temp logging, so you can cross that data with the freq and game you currently have. CSV export is also available.

    I need that. And I'm aware of sys-clk features, thanks.

    This is not for you specifically, i'm answering the original question which reads "Does anyone know if there's a sysmodule for live temp readings?" because you answered with a homecompiled hbmenu.

    Battery damage. The fan also doesn’t run as fast in handheld as it can in docked, so you could also encounter overheating.
