Low framerate and framedrops when gaming. Acer Aspire 5 (i5 8250U MX150 SSD)

Hi,
I am having some problems when gaming in my laptop. I am playing CoD: WZ. At first the game runs smoothly(Avg 45fps), I can play it very well and the framerate is very stable, even when I am moving. After some minutes of gaming the fps start to decreace, until it stucks in 20fps or lower and the framerate gets very unstable, i get 20 fps only when I am looking at a wall.
I have MSI Afterburner and it seems like the performance decreaces when the gpu reaches 70°C, but the gpu usage keeps at 100%. I always game with my laptop plugged, I changed the options in the nvidia control panel to get the maximum possible performance, and I tried overclocking the GPU with MSI Afterburner, but even if i do not do that the same problem appears.
I also would like to know if there is an option to change the fan speed, the gpu voltages, I tried upgrading the bios but i do not know which is the version that I should install.(I used my S/N: NXGTCAA020816064133400 and there is a bios with the name MX130 and i have the MX150 I am not very sure which one I need and I do not want to blow up my PC)

Thank you

My Notebook is A515-51G
Intel core i5 8250U, Geforce MX150, 8gb RAM, FHD Screen, 256 SSD.

Battery must be near 100% charged and still have good capacity BEFORE starting game or charger (especially 45watt charger) cannot keep up with the game load and charging battery at the same time. Jack E/NJ

I always play with the battery at 100% and I also have the 65W charger. I did not use the battery very much since I do not move the laptop a lot, It should be in good health.

Go to the elevated command prompt. Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Compare design capacity with full charge capacity. Post screenshot if possible. Jack E/NJ

Do you have any non-Microsoft antivirus still installed? Jack E/NJ

Joaquinmarto

yes, Malwarebytes, the free version

JackE

Uninstall, don't just disable, it. Windows Defender & MaliciousSoftwareRemovalTool (mrt.exe) are all that most folks need. Jack E/NJ

I create an issue here https://community.acer.com/en/discussion/568747/mx150-8250u-throttling#latest
You have the same problem. Also 2GB VRAM is not enough for modern games. Huge framedrops is possible after some time, even w/o throttling.

Thanks for your reply weter, I would like to know how did you change the gpu voltage, I am using msi afterburner and i cannot change it, i am on the 1.20 bios.

On Linux systems like mine changing it is impossible. But on Windows https://overclockers.ru/blog/d1my4/show/20041/geforce-gtx-1060-unylyj-razgon-i-dikij-undervolting
Simply Ctrl+F in AB. If you want something better, there only one way: hardware programmer (cost nearly 8-12$ on ali) & BIOS from 10W notebooks. There no any variants to change BIOS w/o programmer, also PBE don't support MX graphics for example to change GPU TDP in MSI, only GT1050Ti and up.
