I don't really know where to turn to at this point. The friend who wanted me to join his Pixelmon server is of no help when it comes to troubleshooting.
He had me download 1.8.9-forge1.8.9-11.15.1.1722 in order to play Pixelmon-1.8.9-4.3.0-beta9-universal.
I read that I should never use a "universal" for forge, which I'm assuming I do not have, but my Pixelmon is a "universal". Not sure if that's why I'm having issues.
Anyway, said issues being that when I load my world with forge/pixelmon, my game freezes EVERY TWO SECONDS. Not even joking. I barely move my mouse an inch and it freezes. Takes a couple seconds to unfreeze, go to move my mouse and again, freezing. To the point that my game does "Not Responding" each time as well.
Here's the log:
