Control and performance issues in EA FC 26 (PC - Steam)

Hello EA Support Team. I am experiencing several issues with EA Sports FC 26 (Steam, PC) since its release on 09/19. The first problem is with the controller. I use an original Xbox Series controller, but during matches it shows abnormal behavior such as automatic movements, loss of response, and in some cases the game switches to keyboard and mouse, ignoring the controller. I have already tried changing Steam Input settings, disabling overlays, updating drivers, and even disconnecting other devices, but the problem persists. The second issue is performance and optimization. The game has stuttering, sudden FPS drops and lag even when using settings that are appropriate for my hardware. This makes gameplay very difficult, especially in competitive matches. I would like to know if there is already an update or fix in progress for these problems, and if there are any official recommended steps to minimize the impact until a patch is released.
