my server always feels more heavy when sdk hooks is being used, also ending up with weird crashes that I would not have without the extension.
that's why I prefer running without it. there's no point of reporting it in its thread because people have been reporting similar issues with the extension on l4d2 and the comments have been ignored)
you would need to show some real debug to convince the creators of sdk hooks that there might be some issues with the extension and I neither have time or interest to do so.
I guess one of the builds are more stable than the other, I just need to find the right one for my server. 2.1 finale sure didn't feel right
edit: trying the old deprecated version 1.3. seems to be more light than the 2.0/2.1 versions.
