Yes! Thank you very much.
First I tried the 'ugridstoload'-tip, and it helped to a certain degree. Tried it up to 13.
Then I tried installing the files you mentioned above, plus the file by Shaja mentioned in the thread you linked to. Everything looks great now! The loading times are a bit longer when loading open space areas, but I've been wanting this anyway, since I normally don't have time to read the tips that appear on the loading screens.
Anyway, thank you very much for the tip!
