It obviously didn't read the Aster directory this time, but read the others, and didn't download a new copy.įourth, I removed the whole DLC directory (replaced it with an empty directory), and it loaded almost instantly. Third, I removed the Aster directory from the DLC directory. This had no effect it still processed that incorrectly named directory, and didn't download a new copy. Second, I tried renaming a directory inside the DLC directory (Aster). so that doesn't appear to speed it up.ĭeleting DLC manually speeds it up, but breaks save files.įirst, I used opensnoop on macOS to check what files BL2 was accessing and when, and for me it spends about 30 seconds going through the various files in ~/Library/Application Support/Steam/steamapps/common/Borderlands 2/Borderlands2.app/Contents/GameData/DLC/Īround the time where it's saying 'Checking for downloadable content.'Īt the very least, it opens a lot (all?) of those files, and it takes a while doing so, so I'm pretty sure it's loading them and doing something with the content.

Uninstalling DLC in Steam doesn't seem to remove any content from the DLC directory! Weird. I don't know exactly what it's doing with the files, but it touches each one and takes more time than just reading their contents takes.Īn SSD would likely speed this up (on my SSD I can read all the files in about 10 seconds, and about 5 seconds once they've been read once so are cached in memory 6.5GB would take about a minute on a regular HDD and maybe 2 minutes on a really old one). It appears to load all DLC content in some way during this time (I have most/all of it, about 6.5GB). On consoles, this step might be used to check your DLC, I don't know. This would make sense, as Steam is already managing downloading and updating the DLC files. It doesn't appear to actually do any downloading, and I suspect isn't doing any online checking at all-at least not for a Steam-installed version of Borderlands. Here's my understanding (some investigation, some guess-work) of what happens:
