Poor Performance

[levitheman]

So I have Attack of the B-Team, and I've never ran into problems like this before.

I've played modpacks with upwards of 150 mods in them with no problems.

 

But whenever I play AoTBT it stutters like there's no tomorrow

Steady 50-100 FPS, then down to 2-15. Around every 5-10 seconds.

 

My computer SHOULD be able to handle this:

 

16gb RAM

AMD FX-4100 quad core CPU

Radeon 5500

64-bit OS (Windows 7)

 

 

And I get terrible performance running on Tiny, Advanced open GL, decreased particles, and fast graphics.

These settings landed me 400+ FPS with tekkit.

 

The problem appears to be the ammount of RAM allocated (Its constantly hovering at 80-98%)

 

The highest I can allocate via launcher is 1gb, anybody here who can help me?
 

 

 

*EDIT

Apparently I have 32-bit Java (facepalm) I'll be back with the update

 

**EDIT 2

Java 64 fixed it, lets hope the performance improves

That would be because Minecraft is using 32 bit java.  Get 64 bit java, and allocate 2 or 3 GB.  That should fix it.

Update:

Java updated and running 64-bit, lag is still the same with 4 gb allocated

4 gb allocated, still the same problem

 

At least normal Minecraft gets 200+ frames per second now

Could be your autosave settings. I remember that was a huge problem at some point.

I'll look into it, thanks
