So, I am having MAJOR FPS issues with Minecraft forge. I was going to install it on my server for my friends because we want to have some mods. But before I did this, I wanted to test the mods out myself on my client. I haven't installed any mods yet and just hopped ion a single player world and I am getting 30- 40 FPS. On regular vanilla Minecraft, I get around 500+ FPS with everything on max settings. But with max settings on forge with no mods installed, I get 30-40 FPS. That is crazy! I'm not sure if its because the client is supposed to do that or what.
