I'm using quite a beefy self-made pack (about roughly 48 mods or so). However, I'm also experiencing a lot of lag from the internal server (can't pick up items, occasionally will teleport to a past location, can't place blocks without a 30 second delay, etc). I have allocated a minimum of 6gb of RAM to the launcher, and I have a decent CPU and GPU so I don't think that's to blame. I think I have pinpointed the offending mods (mainly Fysiks Fun with falling blocks disabled, and Enviromine). When I remove the two mods the game is fairly playable, however it would be nice to have them. Any thoughts?
