FPS PACK

On my pc, Vanilla: 300-450fps Modpack: 600fps+

This is one of the best optimized modpack that exist

Good starter-pack for any modpack that you want

###Light weight and its compatible with other mods, i tested Distance horizons with lithospare and it runs very well.

And if your pc can run shaders like on 50 frames, i thing you will have huge boost.
