Starts off fine, getting 120+ FPS, then suddenly mid-game it will drop down to 40, then 30, then 12, then 5-6 fps.
Metrics in task manager look fine, no high CPU, memory, disk usage.
When I minimise the game, Windows is struggling as well. If I close the game, everything returns back to normal and it’s fine. Restarting the game resets the performance and it runs fine.
Will update if I can figure out what triggers it.
