The FTB Infinity 1.7.10 Support section is bugged. The only versions of the pack to choose for a bug report are 1.0.0 to 1.8.2. This causes a lot of confusion in titles that say something like "1.8.2: 1.10.1 Infinity 1.7.10 bla-bla-whatever". That requires fixing ASAP since people will start migrating to 1.10.1 since it is already considered "stable"

Regarding the lag, we deleted the Mining DIM and it all went away, so we found the cause... as to why tho, we have no idea. Someone built a base in the Mining dimension and I suspect that is the cause. Unfortunately, he's gonna lose all his stuff and he isn't too happy about it apparently. I'd LOL but I do feel a bit bad over the situation and don't wish to laugh and make fun of it. Let this be a word to the wise... please don't build your stuff in places that really aren't meant for it. The modpack added a major mod during the last update (Mekanism) and the obvious thing to do would be to reset the Mining World so we can have access to the new ore added by Mek... except since someone decided to build in the DIM, the reset causes issues. Just say no!

Mining dimensions are generally a big contributor to lag on servers. One problem being is caused by the buildcraft quarries that people love to use (they are generally cheaper to make then the ender quarry). Most uses I see is people using a single block of water (since the quarry itself can't dig thru lava, water is needed to turn to obsidian. 1 block of water in a 64x64 quarry to cool lava turns into over 260,000 flowing water blocks. It adds up over time with more and more quarries. First place to always look for lag source is a mining dimension with quarries. I know server owners are happy at least with mystcraft/rftools being able to actually reset just those dimensions instead of the overwold when people quarry there.

FTB randomly freezes every 10 seconds after playing a while: .... This has happened to me before in resonant rise 3 and now FTB infinity.., playing this it runs fine 55-60 fps then after maybe half an hour of play it starts randomly freezing every 10 seconds and i have to exit the whole client and get back in. reading some threads on other forums some people have said about perm gen size but i'm not too sure, i just want help xP.

Make sure to check none of your multiblock structures are in multiple chunks. I had my AE2 CPU in multiple chunks and that what caused the same problem for me.

Question: RotaryCraft Hydrokinetics normally run on water to produce power. The entry in the book describes hat other liquids with higher viscosity would increase the amount of power produced. Now the question is: Where can i find what viscosity/density certain liquids have?

The only other liquid in modded I can think of that would have higher viscosity would be oil... Give that a shot?

Hint: One of the newer Thermal Dynamics liquids is awesome for this application.

TL;DR; NEI Integration lets you use tools in the NEI options to do a dump of all fluids, you want temp < 900, high density, and low viscosity. I've yet to find any liquids that are actually better than water.

Ok so this and hydrokinetics can be somewhat complex so I'll explain the hydrokinetic thing a bit too to save you potential frustration. The most important rule to remember though is that the maximum speed and torque don't change, a hydrokinetic is still capped at .5MW of power regardless of fluid, different fluids just change how much blocks of it are required to achieve that max power. As for the stats the easiest way is an NEI dump, you'll want NEI Integration installed and then you under tools you can do a dump of fluid data, both viscosity and density matter with high density and low viscosity being preferred, water has 1000/1000 for reference. That said for the actual fluid here are the rough rules for height.

  • Fluids of 900 temp or more will destroy the engine. Don't use them.
  • Density has to be positive, no weird stuff with steam or anything that flow up.
  • Both values are important, don't neglect either, particularly viscosity as even a small increase there can penalise you harshly.
  • Technically if you're on other planets with Galacticraft it will scale with their gravity, of course I don't know of any planets with higher gravity so it will just require more height to reach max power.
  • Technical formulas for height required for max torque/speed, you'll want the great one to achieve max power and round up. Ignore if you don't care about it and want to experiment.
    • Height for torque is 200.575*sqrt(viscosity)/dens^(2/3)
    • Height for speed is 1.975*sqrt(viscosity)
All of that means most fluids are actually worse than water either from stats or the fact it's vastly easier to get than anything of the same stats, it will vary from pack to pack but at least in my own fairly expanded infinity there is nothing that is better than water. It's really rather disappointing. Really the issue is that most fluids have the same density and viscosity, and that means that since density in torque scales up faster than lower viscosity scales it down you'll get a higher torque requirement and thus it will be worse. What you need are fluids with a lower viscosity than water and a higher density than their viscosity, to be precise you need a density of at least 5.6234 * visc^0.75 and a viscosity less than 1000 to be better than water, the only fluid I've ever found that meets that is jurassicraft cultivation fluid and that's only because it has a normal density of 1000 but a viscosity of 1 for some unknown reason, I've got no idea how to actually get it though for using.
The only other liquid in modded I can think of that would have higher viscosity would be oil... Give that a shot?
It's irrelevant as you actually want low viscosity but just as an aside forestry honey is the highest viscosity I've found at about 74x that of water, oil is only 10x. Pretty much every MFR, TE, Forestry, and Buildcraft fluid has higher viscosity than water though.
Hint: One of the newer Thermal Dynamics liquids is awesome for this application.
False, well kind of. In the early versions of v7 tectonic petrotheum was the best, with the most up to date formulas the higher impact of viscosity means that pretty much anything with a higher viscosity than water is worse than water which includes all the TE fluids. Petrotheum requires 77 blocks to waters 64 for max power with those.

So Forestry honey would be the best? And @ what height?
No forestry honey is one of the worst fluids I know of, it'd require a 536 block fall to achieve full power. Only the super low density fluids are worse, the best fluid I actually know how to acquire is water. I've yet to see any other fluid that's actually better, you need something with a lower viscosity after all and those are rare, add in that you need a density higher the viscosity and it has to be able to be placed in the world and I don't actually know how to get anything that's better.

I have Void Monster and Mystcraft installed and I don't want Void Monsters in my dimensions. I know there is a blacklist option in Void Monster config but Mystcraft has extreme amounts of dimensionns/ages whatever and I'm wondering if there is a way to blacklist almost every dimension?
