Direwolf 20 1.6.4 FPS stability help!

[shankynation]

Hey everyone! I am having a problem with maintaining a stable FPS in Direwolf20. I have disabled Hats/Hatstand and Opis, while adding Zan's and Dartcraft. I have disabled the minimap radar rendering the mobs, and all settings are set to low.

Quick spec rundown:
GPU - Radeon HD 7870 2GB
CPU - AMD Fx 4100 Quad Core 3.60GHZ
Mobo - Gigabyte GA-880GMA-USB3
16G of ram (I do have the launcher set to use 10G.)

Is there any tips or tricks you guys have to maintain a stable FPS? Thanks!

Set the launcher to use no more than 5gb. Use the jvm arguments from the thread below. Just copy and paste them into the jvm additional parameters box in advanced options.

Adding to what UniZero said, you honestly really don't want to allocate more than 3-5 GB of ram to the FTB launcher. Too much RAM can often slow things down.
