Please try and search for that error message before asking for help. It's been covered a couple of times in this thread already. You're running SourceMod 1.10+ on your server and try to load an extension compiled for SourceMod 1.9 which requires the backwards incompatible IBinTools interface. You'll have to wait until Drifter puts up a build of DHooks compiled against SourceMod 1.10 or use the
fork with detour support, as I've put up binaries for SM 1.10.
The virtual hooks are identical in the fork and the vanilla versions of the extension. So the lag you described would be the same when using the version of DHooks you're trying to load. Are you sure there aren't other problems causing the lag?
