Windows .exe FTB Unleashed Bug (I think)

[Shazam08]

OS, Bit Type: Windows 8.1, 64-bit
Java Version/Update, Bit Type: Java Version 7, Update 35 (32-bit)
Launcher Version: Version 1.3.3
Completed troubleshooting guide: n
Error Message: None, not a crash
Description: After installing FTB Unleashed, I had been playing for a few hours, and it worked great. The fps was hovering around 40, and though they fluctuated it always stayed above 20. At a seemingly random point, as I was walking around, the frames just died. Like, 2 frames at a maximum.
Thinking it was worldgen lag, I stayed still to let it load. Nothing happened. I then tried to lower all my in-game setting down to the lowest possible degree (Render Distance-Tiny), and still nothing. Relogging didn't do much either.
So...what happened? Did I miss something obvious? Is this not a problem with FTB, but with vanilla minecraft? Thanks for the help.

I highly doubt this is a problem with FTB, especially Unleashed.
It may be that you haven't allocated enough RAM, or added java parameters, or it could just be that your PC just can't handle it.

I'm pretty sure hardware isn't my issue, and I know how to fix the RAM in the launcher. What's this about java parameters? (In case you can't tell by now, I'm pretty bad with this kind of stuff)
I appreciate the help!

Sorry if I confused you, this should explain parameters to you, try adding them onto FTB and it may serve a serve a good chance of working.

Thanks, that's exactly what I was looking for! I'll come back to this thread later today, once I've had time to fix it and play for awhile.

Wait, hold on. To apply the parameters, I need to set the RAM In the launcher to 2.0 GB. The slider only goes up to 1.5 GB, due to a 32-bit java. Is that an issue? Will going to a 64-bit java screw anything up on my computer?

It should not cause any problems. 64bit Java is recommended for the reason you specified.

Couldn't of explained better than lavarthan, it really should help your issues and it may be the 32-bit version causing the problems for you.
