Hello everyone. Ive bought RX 5700 XT in spring and noticed that it has problems in at least 2 games - Apex Legends and Fortnite.
In Apex i get 144 fps maximum even on lowest settings, but it always drops to 85 in random parts of the city and game doesnt feel smooth at all. Also FPS graph in RivaTuner looks like a saw blade - here is the example Imgur: The magic of the Internet
In Fortnite i am not having any FPS problems - the game just microfreezes like every 20 seconds which makes it impossible to play. When it does that, GPU clock drops to 60 MHz and GPU load also drops.
Also after doing something on my PC and starting a game I always start getting a noticeable inputlag in all games. Rebooting the PC helps, but i dont know why does it happen - i dont have anything special running in background, also my hardware is never loaded 100%
Specs
Ryzen 5 1600 3.9GHz
16GB 3000MHz RAM dual channel
Sapphire RX 5700 XT
Cougar GX-S750
Voltages and temperatures are fine
What should i try to do to make this card work as it should? If someone needs additional info - please let me know. Thank you.
