Reference issue:
#224
Okay, what happens here is when I install this mod, I had performance problems such as: Lag spike of dealth, gpu bottlenecking, etc, though not fps from 60 to 30 issue in #224
Here is some screenshots for the bottlenecking issue:

As you can see, it drops as low as 5 fps.

You could actually notice that the fps is very good (35-53fps) however the drop is extremely frustrating. I will post more screenshots in the future.
EDIT: The laptop seems to be very hot during the drop, maybe this is a thermal throttling issue.

Yeah I get this issue too, my game like sometimes crashes too, also this should get fixed on the 1.7.10 version too, I'm hoping that both 1.12 and 1.7.10 versions get fixed too. I like get as low as 0 frames per second sometimes, but on a server, its like 30 - 40 frames per second.

If it crashes post a crash report or log please or I can't help.

Since you are using Intel HD graphics, I'd recommend turning down as many settings as possible, try setting to low/none in the ingame weather2 config gui performance tab. Also turn off particle shaders in the same tab. If that doesn't help you're computer probably isn't good enough to run the mod.

This mod actually more demanding then SEUS v11? Idk why, but when I run SEUS v11 on a different profile for vanllia minecraft, there is (almost) no bottleneck to be found.

EDIT: This is not really the crappy gpu issue, is the thermal issue due to I run it on a ultrabook from early 2016. I will try to download Minecraft on my neighborhood's computer (since it's a desktop PC) and install this mod. If it does not happen, this issue will be closed and I'll find a alternative cooling methods (replace the thermal paste, clean out the dust, a external cooling fan for a 13-inch laptop) but if it is happen, then this is an spec issue, so I'll buy another 13-inch laptop with a MX 150 (and the issue will be closed, of course).

Well I think your PC is fucking crappy, you are using Intel Petinum 3558u, which is shit in 2018. You can view the spec here. You gonna buy a new laptop/desktop soon since I can't live with that processor.

I could like upgrade the ram to 16gb of ram so then it will run faster and like get 60+ frames per second which will be a good improvement, and overclock it to more than 2ghz, then that will be the framerate issue fixed. Plus the computer I'm using is one that was released in late 2016.

This issue is not very bad because I still mostly stay on 1.7.10 and rarely touch 1.12.2 so yeah, this issue will not be active.

Cool, yeah can't do much for super old PCs, if it runs bad even with the configs I suggested just remove the mod.

My PC is also fairly new, and should run just as fast as the day I first had it.
