bad GPU usage

[Ihaveswag]

Hey guys, so since lately my GPU usage doesnt seem to be very constant I think its due to the Win 10 update. After the Win 10 update I uninstalled the drivers with all settings and installed the newest ones for Win10. Usually the usage was at 95%+ in 80%of the time I was playing Battlefield, but now it good unacceptably bad and I also notice when my FPS drop below 60 for a moment. It doesnt matter whether I oc the GPU or not, that doesnt matter at all, the stock temp target was 79°C and I also made a custom fan curve with 75°C temp target, but that didnt help and my GPU was noisy with that setting. Well, I am pretty sure that it can worse than with win8.1, also that drivers that I used on 8.1 werent old either, so thats definetly not the case. In the power management settings I had it set to full performance, so thats not the problem either. How could I fix it?
