So I just put a GTX 1070 in my pc, wiped my previous drivers with ddu and did a clean install of latest Nvidia drivers with ethernet cable pulled out so windows doesn't download anything I don't need. My pc is lagging horribly, constant stutters, slow loading and every game runs on 10-12 fps on any settings. The GPU is being detected fine.
Specs:
Ryzen 5 1600
8gb ddr4
GTX 1070
550w psu
Any idea on what is happening?
