I`m trying to cure the graphic problems associated with the GTx 260`s and DX10.I notice that in the file Rome2-redist-directX folder there are 3 files (of varying release dates). If I were to run would it affect only Rome 2 or be applied globally to all programs in the computer.? Also which one does Rome2 use by default?. The choices are:- vcredist x86-80 , -90 , -100. Thankyou.
