Hi, I have recently updated my " AMD Radeon R5 M200 / HD 8500M " graphic card, also I have updated my "Intel HD Graphics 4600" in case this helps in something but I have noticed huge fps drop, lets say in few games, but few other games kept the performance, for exampe, before the update I had 50-60fps playing fortnite, 70-90fps playing CS:GO, after the update I am having 1-5fps with fornite but i am still having 70-90fps with CS:GO. I didn't change anything related to the game settings, I just updated the driver, entered the game and got shocked by that fps drop. I don't know what was my previous driver version and I don't have any previous version on my pc as I have used DDU to get rid of any old drivers. If you need any other information, just ask for it.
I have the same problem, On fortnite i have FPS drops. It was stable 85- 60. Now i play with 20-40 but more stable on 20-30.
