Ok, fine. No need to get defensive. I'll go and get that info. I've never used JVisualVM before, so I didn't know that existed. I'll edit this post and put the info below when I get it. My "on-call" period for work starts in an hour from me posting this, so it might be a while. Thanks. Edit: Well, between updating Java, installing the Dev Kit to run JVisualVM a few times, and reopening Minecraft a handful of times, something changed and It fixed itself. Now it runs (somehow) with the good textures, 32-chunk view-dist., Quark, etc. all without lag. Something changed, but for the better...I'll repost if something makes my computer return to the misbehaving way it was in the OP's video. For now, though, I'm fixed.

Hello, I'm having the issue of the OP, except on a single player game, with no mods installed (except Forge) on the standard resource pack with the view distance any more than 12-15 or so. I have my max RAM beefed up to 16GB, and my computer's specs are very high, so I don't know why I'm getting 1-2 sec lag on every action? I usually run Minecraft with 32-chunk view distance, Optifine, 512x textures, and cinematic-quality realistic shaders. My PC still keeps above 60fps with that setup. I don't really care about the Spigot comparison because, since I still have this issue on single-player with only the bare-bones Forge installed, I don't see how Spigot even factors into this equation? Also, saying Forge "does" way more than vanilla is a completely mute point considering my usual graphics setup and the fact that my computer was running practically at idle with forge and isn't really strained with the Optifine setup either (also considering other games I can run on this PC with max settings.) This is a basic Forge issue. I tried going into the mods-settings under Forge to beef-up the chunks per ticket and other settings, but with little benefit. It helped some from the default numbers, but not any more than I mentioned above. P.S. I posted this comment yesterday, but the forum removed it? Why? Anyway, here I am posting this again!
