Topic on Talk:S.T.A.L.K.E.R.: Shadow of Chernobyl
Would you treat D3DOverrider the same way? I honestly have no idea if it works in the same way as RadeonPro. In any case, I was mostly guessing about the Impossible/Hackable distinction; I had seen that Field of View (FOV) was marked as Hackable, and I figured we had a similar situation for Vsync. If you do change Vsync back to False on S.T.A.L.K.E.R.: Shadow of Chernobyl, the same change should be made on S.T.A.L.K.E.R.: Clear Sky and S.T.A.L.K.E.R.: Call of Pripyat as well.
