I just replaced my old GTX 1660 TI with a MSI rx 6650 XT gaming X. I've used DDU to remove old nvidia drivers but now I have huge 1% fps drops in almost every game. My fps will drop to almost 5 fps sometimes otherwise im at around 100 fps.
My pc specs:
Ryzen 7 2700X
2x16GB RAM 3200MHz
Samsung 970 evo plus 250GB SSD
2x 1 TB Barracuda HDD
rx 6650 XT gaming x 8GB
windows 11
(I'm not good at graphics cards and those stuff so if you have any tips please make an easy step by step tutorial)
