so i was going to play helldivers 2 but cant even stay 5 minutes at the ship or ingame before my pc fully crashes,i have a rx7600 and r5 3600,i have the latest drivers too.
i have almost the same problem with my pc (rx 7600, i5-10400f)(while in dx12 mode game fully freez's my pc in ~5 min from startup) driver updates and full reinstall's using ddu doesn't improve my experience even a single bit but i figured out that by typing in "-use-d3d11" steam start up options let's me play semi stable gameplay with ocasional driver crashes and lower fps.
It's a well-known issue. AMD release a couple drivers targeting this issue but so far no luck. People say turning off global illumination helps mitigate the issue but the problem is still there. All you can do is hope for a driver update or a game update to fix the problem for good.
