I don't run into any of these problems with optifine? What did you do to get these errors? I am on 1.6.4 64 bit java monster.

Optifine is hit or miss as far as graphical issues go. Depends on graphic card and several other issues. I myself have gotten several graphical issues/crashes with optifine.[DOUBLEPOST=1405374539][/DOUBLEPOST]

It's not that they arne't good, it's just that half of them don't do anything anymore.

I don't run FTB packs. But I do know that after some tweaking I got my test pack to run like a charm using J8, unfortunately OSX sucks and uninstalled it after the first restart. It should work fine, but Java 8 still isn't recommended, so it isn't recommended.

Personally, I write my own JVM arguments.

Here are the JVM arguments I use for all of java:
Code: 
-XX:-DisableExplicitGC -XX:-RelaxAccessControlCheck -XX:MaxPermSize=128M -XX:MinHeapFreeRatio=30 -XX:+UseFastAccessorMethods -Xmn=2000M -Xmx=2000M
I use Java 7 update 60.

For a large pack I play I use:
Code: 
-XX:NewRatio=3 -XX:SurvivorRatio=3 -XX:TargetSurvivorRatio=80 -XX:MaxTenuringThreshold=8 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=10 -XX:GCPauseIntervalMillis=50 -XX:MaxGCMinorPauseMillis=7 -XX:+ExplicitGCInvokesConcurrent -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=60 -XX:+BindGCTaskThreadsToCPUs -Xnoclassgc

For my test pack I use:
Code: 
-Xms512M -Xmx2048M -XX:PermSize=256m -XX:+UseLargePages -XX:+AggressiveOpts -XX:+UseFastAccessorMethods -XX:+OptimizeStringConcat -XX:+UseBiasedLocking -Xincgc -XX:MaxGCPauseMillis=10 -XX:SoftRefLRUPolicyMSPerMB=10000 -XX:+CMSParallelRemarkEnabled -XX:ParallelGCThreads=10 -Djava.net.preferIPv4Stack=true

Yes, because they are, and I've told you this in one of our convos.

I just tried your test pack arguments. While I noticed no difference in FPS, my memory usage went down from 30% to a max of 10% in vanilla 1.7.10. Dayum.

Ok, so my arguments + java 8 turned out to be the best for me. I managed to get 60-70 FPS from 5-15 FPS without any arguments. I recommend that you all try them!
Here they are:
Code: 
-XX:ReservedCodeCacheSize=256M -DJINTEGRA_NATIVE_MODE -DJINTEGRA_COINIT_VALUE=0 -Dsun.io.useCanonCaches=false -XX:ThreadPriorityPolicy=42 -XX:CompileThreshold=1500 -XX:+TieredCompilation -XX:TargetSurvivorRatio=90 -XX:MaxTenuringThreshold=15 -XX:+UseBiasedLocking -Xverify:none -XX:UseSSE=3 -XX:+OptimizeStringConcat -XX:+UseFastAccessorMethods -Xrs -XX:+UseCompressedOops -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts
Also, full credit for these arguments goes to Frash23 on the Spigot forums. These arguments were originally made for a non-forge Spigot server, but they worked perfectly in FTB single player :).

^^ This.... All those JVM arguments and memory allocations... everybody seems to have their own version that seemingly worked for them.. Good for you. But my own experience is that this is like some kind of dark arcana. "hit or miss"...

So, general PSA: Let's not get too caught up with this thing.

Also never allocate 7 gigs of RAM as java garbage collection with that is real bad. I usually do 2 - 3.5 gigs of RAM 3.5 being absolute max

I decreased it to 3gb. Also, IIRC Java 8 has something that only garbage collects RAM that is being used (ie. if the Java app is only using 2gb out of 7gb, it just ignores the extra 5gb until something uses it), but I could just be remembering things that aren't real so don't get all upset if I'm wrong.

try it with 3 and see if you get improvement. I didn't know about java 8 having such (if you are correct)

Do those arguments (satanicsanta's) also apply for 1.6.4?

I have only tested them on 1.6.4 ;)

Heres what ive been using for 1.6.4. I cant even generate a world without it. Not sure where I copy pasted the classunloading thing from something in my error reports/logs made me decide to try it. I dont use the FTB launcher so I have to add the memory allocation in the arguments as well.

Code: 
-Xms3G -Xmx3G -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+CMSClassUnloadingEnabled
