I've had my 1050 ti since early August, and it always worked like a charm. Suddenly a few days ago, FPS in Overwatch, Miscreated, Fortnite etc. all went down to 20, when it used to be above 70 easy.
Have you recently installed any updates to Windows or drivers?
Please post your full system spec.
Temps are 60c ish in Overwatch, I haven't checked anything else. I just installed the latest drivers trying to fix it.
MSI GTX 1050ti
AMD A10 7700k APU

Windows 10 Home 64-bit
