Updates. Is there a problem with them?

[Nijuu]

Hey all,
I had already downloaded Psychonauts previously but noticed it needed to update again. GBs of data. Did it.Then days later it prompted me to do it again.Always updates in GB's....
Anyone had issues like this with this game?.
No issues with any of the other games i have installed (about 80 out of 300+ games)

According to doublefine the recent stream of updates are due to the Linux release.

Most of the changes are in the Mac Version and the Linux Version. However, the improved textures and higher quality, better compressed clip-scenes are being backported to the Windows version in these updates.
