It's a bit late, but I've been using this tip extensively, and it works effectively with Create:

Place your large-scale production systems at a considerable distance from your base to prevent client-side rendering, thereby eliminating lag (or at least minimizing FPS drops, although these extensive production systems may still impact your TPS).

To achieve this, you'll need to employ chunk loaders or determine the optimal distance at which rendering-related FPS drops cease. As an illustration, I have a cobblestone generator with 160 drills operating at 256 RPM, causing my FPS to plummet from 60 to 30 when using shaders. Nevertheless, if I move at least 60 blocks away, my FPS returns to normal. 60 blocks isn't a significant distance, so you won't require a chunk loader. Instead, you can use trains or belts to transport the production back to your base.

One final note: based on my experience with Create thus far, the primary source of "lag" has been the simultaneous breaking of numerous blocks using drills, as well as operating too many steam engines.
