When playing Forza Horizon 3, the game runs smoothly without issue for a certain period of time then randomly and without warning freezes and the AMD Radeon driver crashes. Sometimes I can get the game to close with Alt-F4 and the Radeon driver will need to be restarted. Other times I am unable to get the game to close and I need to perform a hard reset of the system using the physical reset button. While I'm currently on the latest Radeon drivers (19.5.1), I've experienced this issue on every version of the driver I've updated to since I purchased the game around December 2017.
My system:
Intel Core i5-6500
AMD RX-480 (8 GB VRAM)
16 GB RAM
1 HDMI 1080p 60 Hz monitor
MSI H110M Pro-VD PLUS motherboard (BIOS ver. 7A15v1C, latest version)
EVGA 500W 80-Plus Bronze PSU
