I have the Witcher-Enhanced Edition, which came with version 1.4, and I went and downloaded 1.5 patch (the latest one) and the Director's Cut. It was fine/is fine most of the time, but last time I played it, it lagged a bit in chapter 1, and at the end i had to turn it down to low because otherwise I couldnt fight the Beast it was lagging so bad. And in some parts of Chapter 2(as far as I got) it was sluggish in some parts of Vizima.Wizzie said:How old is your copy of "The Witcher"?
I remember it used to have some horrible issues with running on Vista, My computer specs could blow it out of the water yet it would always lag horrifically & sometimes not even load past the loading screen.
They did release a patch for it on the official site but it never seemed to do me much good. Apparently the newer versions run alot smoother & aren't plagued with the same problems.
