Performance drop when plugged in on Fusion Pro laptop

[LucOst]

Hi everyone!

For the last 2 months I've been having performance drops when I use my laptop plugged in... It's not instant, but as soon as the fans start screaming and the laptop becomes super-hot it starts "lagging".

How can I solve this? Should I ask the support?

Thanks for the help!

1) How old is the laptop?
2) Have you ever cleaned it since purchasing it?
3) Where is your laptop seated when playing games (e.g. cooling pad, bed sheets, table)?

When your laptop charger isn't plugged in, the system limits the power of the components to conserve battery life. Your FPS is usually capped at 60FPS in this mode, although GeForce Experience can change this.

Because it only happens when the laptop is plugged in, I imagine there's a form of throttling occurring (likely thermal). Thermal throttling lowers your the system performance capabilities to reduce the temperature of the components, and since your system lags when it gets really hot, this is why I think it's thermal throttling.

The best way to check for thermal throttling is to monitor your temperatures with either HWInfo64 or HWMonitor while playing games.

HWMonitor: https://www.cpuid.com/softwares/hwmonitor.html

Alternatively, you can run Intel XTU in the background while gaming and it'll tell you with an indicator the type of possible throttling. This is a little more demanding to run than the other 2 though.

Once you've confirmed if there is thermal throttling, there's a few steps you can take to prevent this.

1) Push the "FN + 1" keys simultaneously to turn the fans on to their maximum speed. It's loud, but it does help with cooling
2) Opening up the laptop case and cleaning dust out of the fans + heatsinks
3) Possibly re-pasting the GPU + CPU (usually have to do this every time you remove the heatsink from the components)
4) Undervolting the CPU in small increments until you have a good sweet spot
5) Purchasing a laptop cooling pad or laptop vacuum cooler. This isn't always a guarantee and evidence shows it doesn't make a huge difference, but I personally use IETS GT300 for my laptop and it reduces the temps by a decent amount:

6) Check if there's CPU/RAM intensive apps running in the background when gaming. You can check this by using Task Manager, or my recommendation would be to deselect some apps from running when starting up Windows (Windows Key > type "Startup Apps"

Hopefully this helps!

What a comprehensive post. Fair play mate!

@LucOst As above mate. I would putting money on this being thermal throttling. Check your temps in HWMonitor as advised above.
