Hi everyone! I'm the maintainer of the MC-Optimization-Guide GitHub repo. Recently I decided to add specific instructions on how to optimize certain modpacks and today I did a bit of testing, and got some interesting results. For the testing I used worlds from GamingOnCaffeine (SF2.5), Kyuuari (SF4) and RagePlaysGames (C:A&B)
TL;DR: Some modpacks are quite poorly optimized
Case #1 – Create Above & Beyond
The first pack I tested was Create Above & Beyond. It runs on Forge 1.16.5 (funnily enough the deafult version of Forge doesn't seem to work anymore so I had to update it to 36.2.39):
As you can see, the fps went from 119 to 232, a roughly 1,95x performance increase. For people with high refresh rate monitors, this means less fps drops when walking through areas with lots of contraptions.
Case #2 – SkyFactory 2.5
An older pack (Forge 1.7.10). Many things happened on the 1.7.10 modding scene in the past year so I decided to give it a shot:
Before optimizations (with OptiFine added)
Similarly to Create A&B, we see a pretty big performance increase, ~1,97x. This isn't as big of a deal though, unless you own a 360 Hz (or higher) monitor.
Case #3 – SkyFactory 4
1.12.2 has a somewhat active modding community, and SkyFactory 4 is still the latest installment in the series (I'm not counting SF One since it's technically a remaster):
Biggest performance increase out of the 3, going from 67 to 292 fps, a ~4,35x boost. On lower-end systems, this can make the game go from unplayable to actually pretty smooth.
Other side effects of these optimizations are faster game and world loading, less RAM usage and lower system load.
The testing method isn't perfect, but it should roughly demonstrate how proper optimization can affect gameplay experience. I'd love to hear your thoughts on this.
