I seriously can't understand what the argument is here. Some people measured performance gains on their system, some couldn't replicate it. Big deal, there's thousands of combinations in terms of PC components.
The "shadow patch" might simply be a primer for the upcoming beta and new patch, or they just had a bit that could improve performance for users with an Ati card, or nVidia card, or whatever else and thought "why not release this before the final patch since it works and will help people in the meantime", or it could be streamlining parts of the game that have to do with the way it interfaces with steam, etc, etc.
I really don't understand where this need to convince everyone really comes from.
Lobisomem says he got better performance, i believe him. Ace says he didn't, i believe him too. Them trying to convince each other that "what happens on my PC surely happens on yours too" is just looking funny
