I opened the Configurator (1.5.1), selected the witcher2.exe located in C:\Program Files (x86)\Steam\steamapps\common\the witcher 2\bin , loaded my preset and all and saved. Opened TW2 and it keeps mentioning something about an entry point or something and the game doesn't launch. What to do ?

Hello ?

Wish I could help. I Haven't played that game in ages... Witcher 2 already has Post-Processing doesn't it?

That was working just fine on me Xeraser. No issues here at all.
