FTB performance optimization

[kev12east]

anyone know how to improve FPS on a mac? some of these hints work...others dont; thanks for any help

Buy a PC.


Sarcasm aside, do just the same thing. Try and see what works. Update everything you can get your hands on (Forge, Optifine, other mods if you're playing singleplayer). Make sure you're not running any background applications eating up your CPU. Post your computer specs if that's not enough, maybe it's just too weak to run FTB at your desired speed.

my computer specs are:
Hardware Overview:

Model Name:MacBook Pro
Model Identifier:MacBookPro7,1
Processor Name:Intel Core 2 Duo
Processor Speed:2.4 GHz
Number Of Processors:1
Total Number Of Cores:2
L2 Cache:3 MB
Memory:4 GB
Bus Speed:1.07 GHz
Boot ROM Version:MBP71.0039.B05
SMC Version (system):1.62f7
Serial Number (system):W80343YGATM
Hardware UUID:590111FB-4969-572B-AE7D-B4549667BD41
Sudden Motion Sensor:
State:Enabled
all mods are up to date, my main problem is the FPS dips periodically, so far my minimum is 4 max is 63.

Do what I described in post #10; Java parameters are OS independent. You have a fairly weak CPU that's likely giving you trouble (although the info you posted did not mention what kind of video card your system has).

Try disabling optifine and turning it on fast + normal, max fps, vsync off. Get the FPS and then enable optifine and set the settings the same and see which one is better.

I have basically the same mac and mine runs pretty well 60+FPS with the settings I listed.

if you have a windows computer you can also increase the priority of the program allowing the computer to dedicate more processing power to it, i have a big computer that can run at 1300FPS so I don't notice much difference.
but on my laptop I ran at about 20FPS, with this added I could get to about 35-40FPS

Task Manager>right-click Java Platform SE Binary>Go To Process>Right Click the highlighted option>Set Priority>High

i tried that just now and crashed every time[DOUBLEPOST=1361147793][/DOUBLEPOST]

Do you actually have a need for Optifine? Does it increase your performance? Optifine heavily depends on your system config and is just as likely to do nothing at all or even decrease your performance as it is to increase it. Every player must determine for themselves whether it helps or not. Also, Optifine Ultra is known to cause issues - try Standard instead if you suspect that it is screwing something up.

Myself, I am very much CPU limited in Minecraft due to my almost 7 years old Core 2 Duo E6600 with DDR2 memory. From another thread just like this one, a few weeks back, I discovered another set of useful java parameters that lowered my CPU load by 10%-20% across the board, allowing for a significant performance increase. Try: -XX:UseSSE=3 -XX:+AggressiveOpts

UseSSE should be adjusted based on what the latest SSE version is that your CPU supports. For me, it is SSE3, but for others it might be different. The freeware tool CPU-Z can identify what instruction extensions your CPU supports.

AggressiveOpts enables additional java performance optimizations that are currently in beta testing and planned for implementation in the next major release. Therefore, the amount of extra performance this gives you will depend on your current java version, and probably change often as you update. There's also a small possibility for added instability, but so far I have not experienced a single crash.

do you know of a program for mac?

I'm using multi mc to launch my instances (I have a few extra mods) and I was wondering, are the JVM arguments the same as additional parameters ? Could I just put those lines in and get the same results as I would with the ftb launcher?

The settings crashed FTB or optifine crashed FTB?

 

[kev12east]

The settings crashed FTB or optifine crashed FTB?

the setting crashed FTB, optifine was disabled, i could move for about ten seconds, then crash.

Does anybody know any good java parameters to boost FPS or load time (apart from -XX maxpermgen)

Does anybody know any good java parameters to boost FPS or load time (apart from -XX maxpermgen)

Most parameters will not directly affect load time or FPS. More likely they will optimize your GC (GarbageCollector) which in turn will optimize java's handling of the memory or how your CPU is used. This might result in lower lag spikes due to better loading times/less garbage in memory etc.
You can try:

• -XX:+CMSIncrementalPacing

• -XX:ParallelGCThreads=2

  (You can use more threads if you have more cores as minecraft only uses 1 core, adjust this yourself and try different settings)
• -XX:UseSSE=4 (ONLY use this if your CPU supports SSE v4)
• -XX:+AggressiveOpts
• -XX:MaxPermSize=128m
• -XX:+UseConcMarkSweepGC
• -XX:+UseParNewGC
• -Xmn128m

Thanks @Lathanael! These help

 

[Hawk Weisman]

Did you update forge like I said? That's a problem with older Forge versions.

Which forge versions have this problem?

Additional mods: Optifine Ultra

Brightness: +100%
Render distance: tiny
Performance: maxFPS
chunk loading: multi-core
Fog: Off
Everything else: set to the fastest option

I have kind of a crappy computer and i've been using a program that makes every single program on the computer stop running except for the essentials so that you can get the most CPU usage for my game. I've gotten a lot of errors and i got someone to help me with that by updating jwlg or whatever that is.. anyways i've been getting about 1-20 fps... i really need a suggestion for some help :/ and btw i'm using 1.5.2 non greg tech beta and i've removed the voxel map mod and mystcraft to get even more speed HELP!

idk what i'm supposed to put here lol

 

[VikeStep]

do you actually have a multicore computer? if not you cant use that chunkloading feature. but apart from that make sure you have the latest java, once you have done that see if you get the error again and make a new thread for it... this thread hasn't been active for 3 months

 

[Jaagnag]

XD didn't notice it was inactive for 3 months and yes i have an updated version of java, maybe i'll try the smooth chunk loading option i'm pretty sure i have a multi-core computer though

 

[Jaagnag]

I do have a multi core computer and i noticed in my console i'm getting 100+ of "removing persistance" things

 

[whizzball1]

Simple.
Get 1.5.2.
And also use the JVM Argument someone said near your thing.

Brightness: 100%
Render distance: Fast
Performance: maxFPS
chunk loading: *
GL:Fast
Fog: Off
Fog Distance: 0.2
Clouds: Off
Trees: Fast
Dropped Items: fast
Clear Water: ON
connected textures OFF

CPU: *
GPU: *
HDD: *

20-70 FPS (depends on what machines are running, where I am in the world, etc)

Texture pack: Sphax 64x

Surprisingly, I am amazed when my computer can get 60 FPS in Minecraft (I don't have the best computer). I find that 50 FPS, is fine enough, I don't need 60000000 FPS.

* I am not home right now, I am on my grandmothers computer and don't know exactly what my computers specs are, and what my chunk loading settings are on.

Fun fact: My friend recently started playing Minecraft, and thought that FPS meant First Person Shooter (facepalm).
