Ah, so I would not need a quad core CPU after all (with the condition that my PC is used just for running Minecraft and no other programs), but a faster one instead?



With my current machine, I am playing Unleashed in a public server and it runs quite well with two digit FPS, but it is a public server so my base follows the rules on the server, limiting 16 power-generators per chunk, etc. I also do not have quarries on the Overworld, but in a Mystcraft age instead. No SS spawner, just the regular one. Not sure how much is you refering by "developed" since I have not reach that stage yet.

Also I am not sure about the meaning of a kitchen sink pack, but I do have already messed around trying to create and modify a new or existing packs, just to try whether the pack will run well on me or not.

Well, if what I will need is a reasonable CPU then I might change my budget plan and consider to buy a new CPU, so the budget isn't too strict but I will not buy high-end stuffs, just the things that allow me to play heavy tech packs with acceptable framerate.

Thanks for your advices! :D

Kitchen sink pack = general pack with all sorts of different kinds of mods, as opposed to specialized packs which focus on a single theme (e.g. tech, magic, exploration, PvE combat, PvP combat) or specialized packs which revolve around a single mod. Packs such as Unleashed and Infinity are kitchen sink packs.

Just note that if you want a new CPU, you will need a new motherboard, CPU, and RAM - your current motherboard won't accept a current generation CPU, and a new motherboard won't accept your current RAM. You can keep the current GPU, hard drives, etc., or replace them if you have the money. You may or may not need a new power supply unit (PSU), depending on what CPU/GPU you get and the PSU you have.

If you get a quad core CPU, Minecraft won't use the extra cores but Java 8's garbage collector will use them, along with any background programs, thus you will still see some improvement over dual core (but you won't double your FPS over a comparable dual core).

And you will still need to get a 64 bit OS.

So what do you need to play ftb. Infinity at least with 20-30 fps?

Not sure what the minimum is. I have an i7-4770 (stock clock rate) and I get at least that much FPS for the most part (I start to lose FPS once the game is using close to 3 GB of RAM due to garbage collector eating more CPU). An i5 will probably get a similar FPS. An i3 will have less performance (only two cores) but you have to ask someone else if it's possible to get 20-30 FPS with a (Haswell) i3. And there's also AMD but I don't know much about their CPUs so you'll have to ask around.

And again, how you build your base will definitely influence FPS.

And you can probably get better FPS in multiplayer than in single player since in multiplayer your CPU only has to run a client, whereas in single player your CPU is running a client and a server at the same time.

A freshly created world and a miracle. Seriously, Infinity, as much as I love it, is not optimized at all. Granted, I play on an outdated Frankenputer built with scrap parts and chewing gum, but I've seen that pack bring some higher end computers to their knees as well. Luckily, I play on a dedicated private server, so most of the actual computation is done for me, but trying to play Infinity in a SSP made me want to get out and push.

Play style will help tremendously, as mentioned above. I have my main base (which is mostly cosmetic, but houses my ME system), a power station (a self feeding, three BR Turbine setup), processing center (pulverizer/SAG mill for ores, cobble gen/compression, automatic Sand/glass, etc.), a prison complex (dedicated spawners to farm mob drops), then a dedicated base for each mod that I delve into fully. All of these are spread across a 5k² area and two dimensions. Travel is made possible by a combination of Mystcraft linking books and RFTools teleportation.

If you can get the cash together, opt for the new motherboard, RAM, and the fastest CPU you can afford (more cores is good for other things, but MC won't use more than one, maybe two for Java garbage collection). If you're still sporting a 32bit OS, its a good sign that you've ridden that horse to its end. Scrap it for parts and pour one on the curb for it.

Edit: I'm not sure if that's a widely known expression, but its a symbolic drink for the dead/gone.

Thank you very much all! :D Could not been greater than this!

For myself I will recheck my budget and the price of the parts I will need (assuming to buy a new CPU and motherboard and RAM).

And I highly appreciate you guys that have been so helpful on this particular problem that I have.

Hopefully this thread might be useful for any other cool guys that need some information regarding this topic.

Again, thanks all! :D

I run an AMD system that I have updated a little at a time over the past few years due to my work situation (I used to just get all my updates at one time).

When the time came to buy my mainboard I made sure to get on that ran with my (then) dual-core CPU but would be compatible with the latest CPU. I had to get ram at the same time but ran the dual-core for a year before buying my FX 8350. You can upgrade slowly and effectively with a little bit of research. I just had to replace a Geforce 9600 GT w/512MB ram with a Geforce GT 610 w/1GB ram due to a dead fan on the video card... I only had $50 to spend or I would now have a better video card :D

As far as AMD performance I can't complain... My CPU is 8-core (not bought for Minecraft) running at 4GHz, no Overclock, with 8GB ram and Java 1.8. With 1.7 packs like Infinity and Direwolf20 I see 40-120 fps with occasional lag spikes, but that's mainly from running 1.7.10 MC. Running the new Vanilla+ pack yesterday I saw 80-100 fps except when I hit "the edge of the world" and had to wait for chunks to load. I may have to add Fastcraft if it isn't there yet as it definitely helped Infinity and DW20.

Just add 2 more gb of ram and install 64bit os and you can play 'modern' packs around 40-50 fps on 6-8 chunks render distance and fast grapichs.. :p

CPU Should be good enough, dual core, hyperthreaded, 3 GHz clockspeed should be plenty, though the GPU isn't very powerful, with an AMD Radeon 8000, with fastcraft and optifine I get 50 FPS while having sphax pureBDcraft x64.

If it's not too much trouble, can you please help me decide if a certain computer would be enough to play ftb infinity.
Dual core i5 @ 2.5 GHz
Intel HD 4000 Graphics.
4 Gigs Ram.
Mac Book Pro Mid. 2012

4gigs of ram only on a Windows machine would not be enough to run the larger mod packs. Mac's may be different, but on my system (i7 quad core Nvidia 680 and 24gigs of ram.. I do video editing) I get decent performance on Infinity with 4gigs dedicated to FTB via the launcher

Thank you. I think if i purchase it I would upgrade the ram. However I am more concerned about the processor and graphics.

CPU has a bit of a low clock speed for MC, and the GPU only being the integrated graphics on the CPU will definitely slow you down. My rough estimate is a max of 30 FPS, averaging about 15 or less. This is based on my experience with a 3.6GHz i7 pulling off 25ish FPS average.

The FPS estimate, by the way, is for a flat world with no machines or power gen.

Processor would probably be slow but usable. I got decent performance on a Sandy Bridge laptop i7 (from 2011), and your somewhat newer Ivy Bridge i5 won't be much slower (or might even be similar in performance) since Minecraft doesn't multithread much anyways. Although my base wasn't really far developed by the time I copied the world over to my more powerful desktop. I wouldn't be surprised if a heavily developed base ran at single digit FPS (but in that case you would get better FPS when outside your base).

Integrated graphics will hurt, though. My laptop from 2011 has a dedicated GPU, so you with an integrated GPU will get significantly worse graphics performance. It should run, but you'll probably have to turn the render distance down a lot, and FPS will probably be poor due to graphics.

For upgrading your RAM, I'd get minimum 8 GB, and recommend at least 12 GB if it will fit (especially if you want to play single player). FTB Infinity can eat a fair bit, your OS will need some, and having an integrated GPU means it will be using your RAM too.

Overall, you'll probably get more enjoyment out of a smaller pack (or you can try a big pack from an earlier version, such as the 1.6-based packs, since I've heard 1.7-based packs are more resource intensive than earlier packs). As well, especially if you decide to play Infinity, you can try multiplayer instead of single player since then you don't need to be running an internal server, so less load on your computer.

For Minecraft, a fast dual core is better than a slow quad core. You most likely wouldn't gain much (if anything) with that computer besides a GPU.

Just note that a desktop will generally have more power for the price compared to a laptop. If you want a laptop that can run FTB Infinity well, prepare to pay a fair bit.

Singleplayer no, on a server still no.

1. Infinity, especially SSP, on a dual core just won't work, there's not enough left over for the OS etc
2. 2.5Ghz is not "fast"
3. Good luck adding a GPU to a laptop

+1 on the desktop recommendation, playing a large modpack on a laptop these days must be torture
