Input delay , PC

I'm experiencing a major issue in FC 26 that makes the game nearly unplayable.

During gameplay, input delay gradually appears and gets worse over time. If I pause and immediately unpause the game, the controls become responsive again, but only temporarily before the delay returns. The issue is also accompanied by FPS drops, screen tearing, and occasional freezes where the game becomes unresponsive for several seconds before recovering.

Another major problem is that if I increase the FPS limit above 60, the game can suddenly drop to extremely low frame rates (sometimes as low as 3 FPS), even though the hardware is more than capable of running the game at higher frame rates. Lowering graphics settings does not resolve the issue.

I've already tested the game on multiple PCs with different hardware configurations, including RTX 3050 and RTX 4050 systems, updated GPU drivers, verified game files, and tried various graphics settings and frame rate limits. The exact same behavior occurs across different systems.

Because the issue appears on multiple PCs and pausing/unpausing temporarily fixes it, this seems more like a game-related problem involving frame pacing, rendering, refresh rate handling, or input processing rather than a hardware limitation.

DxDiag attached. Any help or known fixes would be greatly appreciated.
