I seem to have FPS drops for around 15-20 after playing for an hour in Need For Speed Payback.
Haven't noticed something similar in other games, like R6.
I tried roaming around the city after 1 hour of playing, and got around 40-50 fps, a bit laggy. Then, I turned off the game, chilled for 20 minutes, came back and followed the same roads, and got 60 fps.
CPU: i7 4790k (max temp 73C)
GPU: RX590 NITRO+ (max temp 76C)
RAM: 16GB DDR3
PSU: 650W
HDD: 7.2 RPM 1 TB
I'll provide the temperatures, but i think they are all fine, what might the cause be?
