SSP WorldGen and Chunk Loading lag Issue.

[RitoruSuta]

Hello, recently i've got a new computer. While everything else seem to run fine, minecraft seem to run crappy only in SSP. Is not really Fps problem as im able to play SMP without any issue at all. The issue seem to be related with chunk generating/loading. When i generate or load a world, it pretty run at 1fps or freeze for the first 10 seconde, then lag and have low fps for a minute or two as chunk take a bit of time to appear. Once loaded, performance come back to normal... until when i start moving around or generating new chunk, it will jump (mouse jump migth be include too) and fps drop (Ex: 60˅10˄60˅10) until loaded. In contrary to my older computer, while i had low fps, world generation was smooth, even when playing modded.

As it a new computer, there not much install on it and everything is up to date, Also i've tried Optifine, but not really much changed. Assigned more RAM didnt help too.

I dont know what the causing the issue, something to do with internal server maybe? Have any idea how i can fix it? Java argument maybe.

Bump. No one to give tips what could be the issue?

More ram would help a little, add another 4GB, the larger FTB packs like about 3.5GB assigned to them. It will still not be smooth though as your system is pretty low spec.

I forgot to mention it was also affecting Vanilla, as about RAM is fine. Anyway, i did try to allocate more without no result at all. But what i dont understand is why it having difficult running SSP, as my fps kept dropping but in multiplayer is stay high (60 windowed, 30 fullscreen). Even if fps was mediocre with my other machine, it didnt have that problem of random fps dropping and lag from loading new chunk.

If you are noticing this problem in 1.7.x in a custom pack it is most likely that you have not addEd fastcraft. Without this mod chunk generation is absolutely appalling.

 

[Steve_59]

Allocating RAM is very different to adding RAM to your computer, 4GB is not enough for FTB.
You also did not post your harddisk specs, a 5400RPM drive is going to cause stuttering when chunks are generated. A 7200RPM drive will be a little better and an SSD will show very little sign of stuttering. However your E7400 CPU is going to be causing most of the issues. It has the same performance as the X2 235e so there is no CPU boost in performance comparing this PC to your older one.

@Steve_59 I know that, just my BIOS is limited to 2x2Go DDR2, until RAM affect World Gen and cause slutter, i didnt have that issue with my other machine that only have 2go. Anyway, i dont need that much RAM for what im doing with. About the Hard Drive it a ''Seagate Barracuda 7200.10 ST380815AS 80GB 7200 RPM 8MB Cache SATA 3.0Gb/s 3.5'' and is the same model on my other machine except it as 160Go.

@Chris Becke Not really that, last pack i've tested was Revenge of the C-Team and it have Fastcraft. It migth help but it hard to compare as im already having difficulty with chunk loading in vanilla hitself.

Im suspecting it migth be the Intel Core having trouble with Internal server, i remember before having issue with mouse lagging and image skip when turning view before. Those are gone but i still need to deal with the WorldGen and random fps drop. I will do a quick test in a couple hour with my other machine by transfering RAM and GPU to see if i had a similar issue or not. Is there Java Argument that migth help reducing and smoothing WorldGen?

Yeah the difference between SSP and SMP is that on a server the server does half the job for you.

I see several issues that are probably all contributing to your performance issues in SSP. I will rank them in what I think is the worst:

1. You have VERY low RAM for a 1.7 pack. You will have to dedicate(dedicate as in nothing else can use it) somewhere along the lines of 3-3.5BG of RAM to Minecraft alone for a larger 1.7 pack. Since JAVA is crap, it will often end up using 20%+ than what you set it to. Then your OS needs about 1-1.5GB. And then there is browsers, background processes and whatnot. So as you can see, this comes to a total over 4GB. In this case your computer have the choice of crashing or start using your harddrives as RAM instead. And harddrives(even the best) are enormously slow compared to RAM. This is well-known to cause reoccuring "lag" spikes when the game cannot process data fast enough due to the bandwidth of the "harddisk RAM", also called Pagefile.
   
2. You have not specified what harddrives you have at all. This leads me to believe that they have not been prioritised at all. If you only play on servers and dont mind the LONG pack loading times, then sure you can get by with whatever. If you want to play large packs in singleplayer, then you NEED a fast harddrive. I would go so far as to say that an SSD is almost a must for a satisfying experience. This is why it breaks down completely for you when you force chunkloading and specially when generating new chunks, where LOTS of data needs to be read/written.
   
3. Your CPU is very slow for a CPU intensive game as Minecraft. Singlecore performance is key in minecraft since it does not multicore/thread very well(some mods take advantage of multicore now, but minecraft itself does not). As a comparison I scrapped my 7 year old 2.8GHz I7(4 core, 8threads) half a year ago, because it was getting much too slow for Minecraft.

With a quick glance of the specs, it smells a bit like this PC wasn't built for gaming, but just general browsing, streaming and other light work. EDIT: Just looked up the GFX. From what I can gather its a passive cooled card from pre 2011 meant for silent home theatres and the likes...

Im somewhat wondering if you guys read the entire post before posting an answer but anyway, im more concerned about Vanilla, not from a modpack.

I did my little experience by swicthing GPU and Ram with my other machine and well, seem it the Graphic card that migth interfere with SSP Performance. Sure FPS are maybe higther but when i removed the gpu, i didnt have that sluttering lag from loading new chunk. Unfortunatly i can't test that theory on my newer machine as i dont have another GPU to test it and dont have an integrated one. By checking the DxDiag, is it something to do with shared memory?

 

[Steve_59]

I don't think there is any advice we can give you besides fastcraft and maybe optifine or similar, but I don't think even they will help. I really get the feeling I should not have replied to you in the first place, I looked over your PC specs and saw instantly that you will never have a good experience with ANY flavour of Minecraft. However, as no one else wanted to assist I did, but you really did not like what I had to say, or any of the other replies, which are very similar to mine IE RAM low, CPU low, HDD low. Basically your system is not of high enough specification to give a comfortable experience, for you, to enjoy gaming on. I am not going to bother replying anymore as you seem very dismissive of everyone trying to assist. Good luck with finding an answer.

Sorry if i look dismissive or mean in a way as im not very good to explain stuff, and any help are alway welcome. It just alway see the same type of answer (RAM, add more RAM etc.) or try optifine and etc as i already precised about it, is not helping me much in this case. It as only help me once to understands why i was getting OpenGl in an older post with my older computer. Im aware i will never get a maximum experience with minecraft and i dont really care, i'd just play for fun and relax. Still with those spec, i where able to get decent and smooth gameplay using optifine at low setting. But now i've got something better, it shocked me to see how SSP was unstable compared to my older computer, so i through it was maybe something to do with Intel Processor and was maybe expecting Java argument to fix it. But from my test, look like it was (probably) my GPU causing instability with Loading/Generating chunk causing lag.

 

[Steve_59]

I appreciate your problem, if you still have the older computer then look at setting up a server on that, it will take a lot of load off your main PC and you may find the experience suitable.

If you want a playable experience on that system then don't upgrade to MC 1.7.x - the system requirements for acceptable performance were much much lower for MC 1.6.4 and lower. In 1.7 everyone seemed to go crazy adding more textures, and modpacks that worked fine on 1.6.4 became untenable when ported to 1.7.x with OpenGL errors spamming the log.

--
On that, a question is, when you run this poorly perfoming game instance, do you have the log open? Is it filling with OpenGL errors? That would be a clear indication that you need to have a video card with more video RAM.

 

[RitoruSuta]

That seem a good idea, but setting up a server would be impossible for me, i'd be missing a power cord and usb wi-fi key and anyway i've already tryed to set one a long time ago foe me and a friend and it never worked. But i can alway use the 14 day trial realm for that, why not.

As it late, im gonna tries my other GPU tommorow, an EN9400GT Silent 512mb DDR2 (i'vve forgot about it). Maybe it will work better.

@Chris Becke Haha, nice to know. That answer a part of one of my older post, i was wondering why can i play crashlanding (1.6.4) but not ftb lite 3 (1.7.x). I try that tommorow, migth get better chance with older pack, and maybe playing beta for nostalgia.

Update: Swithing Graphic card did help with performance, as even is it noticible when playing Terraria. Even having a better Base Score (3.9 to 4.9) from window experience index. But in a way i dont understands why my Nvidia Geforce 9400 GT 512mb ddr2 is more performent than my ASUS EAH5450 Serie 1Go ddr3.

Main issue that was causing trouble was my Microsoft Wireless keyboard/mouse, i've already had trouble with it outside minecraft (Intense CPU usage, mouse lag and performance drop). I've noticed when testing with the two Graphic card, i didnt have much issue generating chunk and screen jumping when using an another keyboard/mouse.
