I'm another who plays with keyboard and mouse. Make sure when the centaur charges you that you keep Lara's guns locked onto to it at all times (hold the combat button down if you're on manual combat mode). The adrenaline dodge move you need won't work unless Lara's weapons are locked onto her enemy. Lock Lara onto the target, but stop shooting and run to the side. When the arrows appear in the corner of the screen, press the crouch button, and then wait for the target to appear on the centaur's head, and shoot.
If the centaur targets you with the green ray, make Lara crouch so you don't get turned into stone.
Once you've pulled off a successful adrenaline dodge move and stunned a centaur, press the grapple key to lock the Lara's grapple onto the centaur's shield, and then press interact to pull the shield onto the ground. Once you've gotten both shields on the ground, stand by one of them and shoot the centaurs until they target you with the green ray. Then quickly pick up the shield so that the ray gets reflected back at the centaur and it gets turned to stone. When it's stone, you can shoot it and hurt it. Repeat the move with the shield until they're both destroyed.
