My understanding at first was as following: - sv_pure 0 completely off, no checks. - sv_pure 1 allows custom content too, as long as it doesn't override the native Steam content. If you want to override this (example: an altered de_dust) you use the whitelist file. - sv_pure 2 only native Steam content, exception: you can build custom maps with bspzip and than it will be added to custom content (so clan match servers can still play non-default maps like de_cpl_mill).
True, or not true?
