With CLS my modpack loads about 20 seconds slower.

I have small tool that fetch debug.log and gather all [...] took 0.001s values.

Without CLS there is more than 200 mods that loads less then 0.1s.

With CLS mostly all of this "instant" mods increased their load time for 1.0s - 0.1s, so whole game load time increased for about 25s.

This how my loading screen setup looks like:

I don't know how CLS working, but it feels like it drawing screen in sync mode, that cause little lag for frame rendering for each line of status log, so multiplying to 200 it adds this lag.

How to fix that? Fancy loading screen should not cost 20 seconds!

I think this might be caused by the CLS config option smooth_init defaulting to true rather than false - can you check to see if changing it does anything?

Right now my config option set to false:

    B:smooth_init=false
    B:use_custom=true
    B:use_frame=false

Should i enable it to true?

No, I was hoping smooth init was the cause of this. Setting it to true would probably make it much slower then.

I'll try testing it locally - have you made any changes to the modpack (other than adding CLS) from what you're testing ATM and release 0.41.1?

have you made any changes

Yes, i did, but i didn't pushed them yet. I would make new release in next few hours.

Ok, from some local testing:

• Forge (default): 8:18
• Forge (disabled): 7:23
• CLS (smooth_init=true): 9:39
• CS (smooth_init=false): 8:46

So yes, CLS seems to make it slower. I'd have to start debugging a bit deeper to find out why though. smooth_init intentionally sleeps so it's always going to make it slower, but every frame of the loading screen has to sync anyway - even with forge - so I'm not sure how much I can speed this up by.

I would try to "play with options too if this would help.

1. I tried to load with I:fps_limit=10 and nothing changes.
2. I also though there is problem with time getter, but even removing it, nothing changes, still slow.
3. Set I:fps_limit=300 wont change load time too
