Acer Aspire VX5-591G-721N low fps without A/C connector.

Hi everyone! I had bought this laptop and I have this problem the title. I had already tried several options like:

 

-High performance mode in w10 settings

-Turn off in nvidia Experience the limit when using battery

-HIgh performance in Nvidia control panel

 

I do not know what more I can do, when using A/C I am around 120-140fps in CS:GO but without 60-70...

 

Thank you!

 

pd: some screenshots about what i had done

    It is normal, to make the battery life longer. While the laptop is not charging it limits the CPU and GPU frequency to save power, otherwise your battery would be drained very quickly.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    I spoke with ACer technical service in Spain, they told me that it shouldn't happen... I don't know if that person is confused and yuou have reason or maybe there are ways to increase performance.

     

    By the way, is there any option to increase cooling? when the A/C is unplugged the fans are not working very hard...

    I own a gaming laptop and it drops performance when unplugged from charger. Also sometimes the people who work for Acer don't know what they are talking about.

    My laptop is Acer predator 17x and it loses about 45% performance when not connected to charger. I tried with high performance power plan and setting the CPU limit to 100% but still the fps is still low. I kept a record of the CPU's frequency while on battery and it is the same as when the laptop is plugged in, but when I put the CPU under load(playing game) its frequency drops almost with a half from the maximum frequency. Also the GPU that gets downclocked. when on battery the highest frequency it reaches is about 40%-50%(when loaded) lower than the maximum frequency even if I have set to 'prefer maximum performance' from power management mode in Nvidia control panel.

    It is most likely a BIOS setting or probably somewhere from the registry in windows it is set to downclock the components while on battery.

    Anyway I don't think this matters, because if you game the battery won't hold more than 1-2 hours and if it didn't downclock the CPU and GPU by 50% then the battery life would twice less 30minutes-1hour. They have designed the gaming laptops considering that because of the poor battery life no one would start gaming away from the charger.

    If anyone passes by this later...

    I think the fix is to right click on battery, click power options, click change plan to any plan that you have selected, click change advance power settings, go down to intel(r) graphics settings then to power plan, and change both to maximum performace.

    Ven 98 is correct and it doesn't matter what Performance you set your Notebook to. Gaming Laptops are NOT designed to game on battery power at High Performance and the Laptop WILL limit despite setting to High Performance. It isn't a problem and nothing is broken

    Thank you and have a blessed day  B)
