Best Driver For AMD RX 570

Hi i play fortnite on the AMD Rx 570, i didn't really use to update my graphics drivers as i getting enough performace out my GPU (around 120fps stable) Then this one of my friend comes along and says you should updrage your gpu drivers and you will get even more performance, i listened to him and updated my drivers but after updating my driver i started to get around 70 - 80 fps with alot of fps spikes, i don't remember the old GPU driver's version i have tried many like (24.1.1, 22.5.1, 22.6.1, 23.5.1, 23.5.2, 23.7.1) yet none of this give the performance i used to get, there were no extra updates when i updated my driver, i didn't change any settings infact i lowerd the 3d resolution down to 50% ( i used to play at 100%) even still i get low fps and fps spikes.

​

if anyone knows a fix to this it will be very helpful!
