Wuthering Waves PC Resource Cleanup lets you remove eligible game files you’ve already experienced, such as watched cutscenes, to make room on your drive. Version 3.8 also introduces Full and Basic resource downloads on the official PC launcher. Both features sound useful, but they’re currently limited to selected test players, not everyone updating on 12 November.
That distinction is easy to miss in the patch preview. If Wuthering Waves PC Resource Cleanup is missing from Settings, or your launcher doesn’t offer a Basic download, it may simply mean your account wasn’t selected for the test. Here’s what the choices do, where to find them and what happens to players outside the rollout.
Who can use Wuthering Waves PC Resource Cleanup?
Kuro says it will provide the updated launcher to a limited group during Version 3.7. Players granted test access can then try the new resource options during the Version 3.8 pre-download. The cleanup feature goes with that test, so it also requires eligibility.
For everyone else, the official PC launcher continues to use the Full resource download by default. Kuro plans to bring the features to other PC platforms that don’t use its official launcher after the test, but hasn’t announced a general release date.
The Steam migration is separate. Steam players are being moved to Kuro’s Official Launcher in Version 3.8 and will be able to select graphical resource tiers. That doesn’t mean every Steam user gets the limited Full/Basic package test or the Resource Cleanup tool immediately. See our Steam reinstall instructions if that’s your platform.
Full vs Basic resource downloads: what’s the difference?
Full downloads the majority of available game resources in one go. There may still be some files to fetch after you enter the game, but most content is installed ahead of time.
Basic downloads only what is needed to launch the game. Once you’re playing, additional resources are downloaded automatically according to your account’s progress. This may be a better fit for someone trying to minimise the initial download, although you can expect more resource downloads later as the game needs them.
Neither option guarantees a fixed amount of permanent storage savings. Story progress, new content and future patches all affect the space needed. Kuro hasn’t promised a universal size reduction for every PC account.
Where to find Wuthering Waves PC Resource Cleanup
If you’re part of the test, go to Settings > Other > Resource Cleanup. The game identifies eligible files, including watched cutscenes and environment resources connected to content you’ve already visited. It also shows the total cleanable size before you choose to remove them.
The Wuthering Waves PC Resource Cleanup feature is designed to remove files selected by the game itself. Don’t try to recreate it by deleting random folders from your installation directory. That could leave the client missing files it still needs.
If the menu is absent after the update, check whether your account has test access. Simply installing Version 3.8 isn’t enough to unlock it, and there is no story mission or account level requirement you can complete to force the limited feature to appear.
Are UHD, HD and SD the same as Full and Basic?
No. UHD, HD and SD are different quality tiers for graphical resources. Full and Basic describe how many game files are downloaded initially. One changes asset quality; the other changes how much is fetched up front.
If you’re trying to save space, check exactly which choice your launcher offers. Selecting Basic doesn’t automatically mean you’re switching to low-quality visuals. Equally, selecting HD doesn’t mean you’ll have downloaded every optional story resource in advance.
How much space is needed for the 3.8 update?
Kuro lists a 13 GB PC pre-download that requires 15 GB free space to complete resource integration. That’s the download requirement, not the game’s total footprint. Its separate device requirements list 100 GB of PC storage and recommend an SSD.
For the Wuthering Waves PC Resource Cleanup test, the useful step is to check the space the game says can actually be freed, rather than relying on estimates for another player’s account. For all the 3.8 download and maintenance timings, see our update time and storage guide.
