I still see the same jittery/stuttery video behavior. Thanks for your suggestions though, these are probably good settings to have around anyway since I have 12 GB of RAM on the client and 8 GB of RAM on the server. > make.conf WITHOUT_IPV6 would affect ports, src.conf WITHOUT_INET6 would > affect the base system (thus rpcbind).

I'll have to add the "nooptions" since I like to build as close to GENERIC as possible. Mostly the WITHOUT_* stuff in /etc/src.conf is to reduce my overall build times, since I don't need some of those tools. I'm okay with the messages though; I'll probably comment out WITHOUT_INET6.
