I often play Fortnite and have actually always had 60 fps at the highest settings, but lately it has been so much less that I have around 20 I have ne GTX 1060 MOBILE i7 8750h ASUS TUF GAMING FX 504
Above all, everyone else has a lot more fps with the 1060 mobile so 90 and why I have such a lousy crisis
Is apparently a bug, my old GTX 970 also has lags and freezes in Fn all the time. Is probably due to the new chaos, but you can try whether changing the Dx version in the settings helps, you may be playing on Dx12 and there's not yet so mature, there are often such performance problems.
Since it is a mobile GPU, I would check the temperatures
How come?
Dx 11/12 doesn't make it better
Aida64 or hwinfo64 or MSI afterburner
66 degrees is normal
Yes in the green
