With version 1.1 I had many CTD (crash to desktop) but I fixed it by using CFF Explorer and allowing the TESV.exe to be able to use >2gb of ram. When 1.2 arrived I had lots of missing textures, see through walls, also CTD was not fixed. I couldnt enable >2gb of ram as Brethesda blocked it and recieved error message. I went back to 1.1 with no problems. Now 1.3 has brought more CTD, not able to play at all as the amount of CTD. Can't go back to 1.1 as that removes fast travel. So like Fallout 3 the game is not able to play ( Fallout 3 was that I was unable to save game as it crashed the game, waited months for patch).
So goodbye Brethesda, now I go to Star Wars the Old Republic, done 2 beta weekends with that and Bioware know how to make PC games as I recieved no bugs what so ever durring the Beta weekends.
