Laptop with 1050 poor performance?

I bought the Medion Erazer P7651 a 1000 euro laptop 2 years ago (gtx 1050 4GB and i5 8250u) and when I play Fortnite I don't have 50fps on 1920x1080 and lowest settings, is that normal? And it came from the repair yesterday because the mainboard was broken

You got ripped off and a notebook is not a gaming pc (unless you have a gaming notebook)

What did they replace if the mainboard was broken? With the technical data you should actually achieve 60fps in medium settings

The mainboard

I have a gaming notebook

It is. An office notebook certainly doesn't have a 1050

Then bring him back. Apparently something was not done correctly or forgotten during the repair. Does the fan still run from the laptop?

Everything works normally

This is normal because your CPU goes down on its knees with these multiplayer players. This is a U-power-saving CPU, the clocks are not particularly high because they have to run with little power. 50 frames max is fine for a 0815 notebook.

Let Windows run at peak performance and see if the CPU clocks higher.

EDIT: Install the current Nvidia driver and make sure that the Nvidia is used in the game and not the internal Intel.

4GB is already very weak you will not find my samsung galaxy a70 (c.a 300 euro) has twice as much ram but that should just be enough for fortnite

If everything runs normally everything is fine. You just said your laptop has been slower to repair. In that case, bring him back.

Ok then they pulled you off. The processor is soldered to the mainboard on laptops. The processor is almost impossible to get off the old mainboard without breaking it and they definitely haven't got the processor again. The ram is probably also soldered, you can't get it off the mainboard so easily. I think they just told you that they replaced the mainboard and then changed more

If it were just a constant 50 fps and a graphic where I would see 20m away

It's 8GB ram

See edit

System and games should not be on one partition with an HDD. Then you should partition. With an SSD it doesn't matter as long as there's enough free space available.

I'm sorry that that was your ram but still 8 GB for a 1000 euro notebook is also weak

The drivers can't be installed

Are on the ssd

If they changed the motherboard, you may have been disconnected (if it was made by a dubious company). For laptops, the CPU, RAM etc. Are permanently soldered to the mainboard and are rather not reusable if you remove them.

Look in the device manager to see if it is the same CPU.

How much free space is still available?

Get the latest driver for your card from the Nvidia website.

Then only uninstall the previous driver with any software. Then the new install.
