Hey everybody,
At first, picking locks was a bit of a crap shoot for me, releasing the LMB at just that right moment. Well for those who do not know, there is an alternate method to setting the tumbler.
Instead of releasing the LMB, It works out easier for me if instead I hold down the LMB and then when I want to set the tumbler I hit the RMB. Have not broke a lock pick in quite some time now.
Hope this works out and helps anybody having issues with picking locks.
