I think @BarbasTheDog has it spot on here - I found I just literally couldn't run DW20 1.7.10; my PC is low end (32bit OS and 3gb of RAM :/ ) however I've had much more success using FTB Lite 2 (thought I'd better stick to 1.6.4) and porting in a few extra mods I really liked.Are there any plans to give minimum estimated system requirements for certain modpacks?
Are there any simple ways to speed up or streamline a modpakc and game? I'm using Direwolf20, and I'm mostly a magic fan, but I like the automation option. Running with 4gb ram here, and it's not exactly easy for me to play.
If you try that or FTB Lite 3 and add in a few mods to give it the feel of DW20 (though you might have to give Botania a miss...!), you may find an enjoyable modpack that doesn't melt down your computer!
