rx 6600 xt performance issues fortnite

every time i load up a game in fortnite i go down to 40 fps and considering that i have an rx 6600 xt, 550w psu, 16gb ram, and Ryzen 5 5600g it is not my system. I do not know why it is doing this, it is working perfectly fine for my friends who have similar specs as me. please help me find a solution.

i seem to have the same problem, any fix?



no i haven’t found a fix but you could try and use dx12 see if that helps 


Hi, I have the exact problem and Permance Mode utilize the GPU with only 10-20%, terrible slow. DirectX 12 is better but still low utilization and low watt usage. 

I have everything from 30-160 fps, crazy... the sudden drops is the most problematic.


Overwatch is fine, and its utilization is over 80% there, running at max speed all from 140-220 fps at high specs. 

Horizon 5 seems fine as well, with 100+ fps

EDIT; DX12 + High resolution + FPS limit'er to 300 fps works better, but still drops to sub 50 now and then (high 144-200) .


I have tried it with a i7 4770k and a i7 5820k


same for me other games work perfectly fine but fortnite on performance mode and dx11 works terrible
