Hello,
I've been playing on forge for these last couple of days, and it's been running perfectly. I'm playing single player with 14 mods installed (list below). Last night when I turned off my machine, it was working, once again, perfectly. No sign of any performance issue whatsoever. Get on it this morning, having not changed anything at all, and Minecraft is completely unplayable, even in a new world or in a Superflat world with minimal object enabled.
It's so bad to the point where I can get up and do something else in the time it takes for the pause menu to open. There are occasional spikes lasting 1-2 seconds of it running fine, but the rest of the time I'm completely stuck. Can't look around, can't walk, can't open the inventory. Nothing. Menu and home screen work fine. World's create and load fine, take normal time to close. It's only playing the game itself that lags horrifically, even without a single mod item in the game world. Nothing else on my computer is having this issue in any way.
Once again I'd like to make it clear that I have made no changes in any way to my computer or to Minecraft between when I closed the game last night, and now - when it is totally unplayable.
Any and all help will be greatly appreciated. I've enjoyed using these mods for the last few days and I'd hate for it to suddenly have to go.
The mods I have installed are:
Industrial Craft 2
Immersive Engineering
Custom NPCs
Vic's Modern Warfare mod
Immersive Vehicles
Immersive Vehicles official pack
Immersive Vehicles Trin parts pack
Immersive Vehicles Civil car pack
Immersive vehicles military car pack
df roads mod
I am playing forge for 1.12.2 and all of the mods are in the most recent release version for 1.12.2
*Edit:*
After removing all of the mods and trying again, there's no lag at all. I'll work through them to see when the lag starts to appear, but I'd still like to see if there's a way to fix it without removing any of the mods for good. As I said, it was completely fine yesterday. Very strange that it starts to lag so badly after being fine.
