When I used it it was a patch that just replaced LBS with DQS entirely. That said I feel like the bulging knees and elbows looks just as bad as LBS skinning errors anyway, so either way it’s not really worth bothering with to me.
There are some methods of doing DQS without bulging while retaining the benefits of DQS in preventing the skinning errors present in LBS, but they involved more in depth patches than DQS itself or even OCoRs would.
