I'd like to run dedicated server which will show up on dpmaster.deathmask.net but only when I start it. Is it good or *naughty* form?
I think this is all fine
Do you recommend to play with any server-side mod or with *clean* OA?
It's up to you I'd say.
Here are a few drawbacks if using a mod :
- mods are rarely libre softwares (and, depending on mods/additions, it's weird to play OA to finally get back something which looks like Q3 and reuses most if not only Q3 assets)
- mods require players to set their autodownload on, or to install the mod themselves
Mods are not meant to fuck up OA, I think noghost is tested/known enough to be considered safe.
Delag helps if you have high ping, personally I consider it to be an improvement.
If you have low ping and think it's hard to hit, it's harder to make a diagnostic of why you experience "lag".
Edit: Noghost and both "clean" (vanilla) OA have some unlagged code, so I don't know how it's dealt with, but I doubt it conflicts. (someone may confirm)
