FC 26 PC – Match drops FPS to 5 and permanently breaks performance

In FC 26 there is no FPS or lag issue on the main menu at first but as soon as I enter a match the game drops to around 5 FPS and becomes unplayable. After exiting the match the main menu also stays at 5 FPS and the performance remains broken until I restart the game. FC 25 runs perfectly smooth on the same PC with no performance issues at all so this is clearly not a hardware related problem. This appears to be a serious FC 26 PC optimization bug possibly related to resource handling or a memory leak. My computer is more than capable of running the game and the issue is entirely caused by FC 26 bugs.

Restarting the game is the only temporary fix.

Many other PC players are reporting the same issue.
