My gun also keeps firing. I reinstalled Battlefield 4, reinstalled mouse firmware, and changed the mouse twice and never worked. I kept on resetting the settings but it doesn't work. I just got Battlefield 4 last weekend, and I don't want to know that I just wasted $49.99 on a broken video game.
My computer specs, if it helps:
Mouse: Logitech G500 Gaming Mouse
Keyboard: Microsoft Natural Ergonomic Keyboard 4000
GPU: NVIDIA GeForce GTX 750 Ti
CPU: Intel Core i5-4670k
Motherboard: ASRock Z87 Extreme4
PSU: Corsair 600 watt modular power supply
HDD: WD Caviar Blue 500GB
SSD: 240GB Crucial M500
I really really want to get back into the game. Please find a fix quickly. I looked on all the BF4 Forums and there are no solutions.
Thanks
