I understand there are a number of high res texture packs running around out there. I have seen some of the threads announcing this or that pack, and the vote on an official one, but would like a more thorough discussion on the topic.
a. Which are the most popular?
b. Are all of these considered acceptable, or will some trigger modified content problems?
c. Is there much of a performance hit in the frames per second?
d. Are there any game advantages other than aesthetics?
Thanks for the feedback.
