No effect in 1.20.5 and later (test further optimisations)

[yumunet]

I tested with an Intel Core i5-3470 (4 cores 4 threads, base clock is 3.2 GHz) and cannot see the effect in Minecraft 1.20.5 and later.
I can see the effect in 1.20.4 and earlier.

I don't know if this is a bug of Noisium, if it is an issue dependent on my environment, if the world generation has been optimized in 1.20.5, or if it is a compatibility issue with Chunky.
However, I found it odd that it would not be effective with such a slow CPU.

Test

Generate a 2000x2000 range with Chunky as in the benchmark on the Mod page and look at the logged times.

Fabric 0.16.7.
8GB memory is allocated (Argument: -Xms8192m -Xmx8192m -XX:+AlwaysPreTouch).
Video settings were lowered as much as possible (Render distance: 2, Simulation distance: 5, Grapchics: fast, Smooth lighting: off, Max FPS: 30, etc.).

PC Specs:

• OS: Windows 10
• CPU: i5-3470
• GPU: (integrated GPU)
• RAM: 16GB DDR3-1600
• Disk: SATA SSD

Do this step 3 times each.

1. Create world (Game mode: creative, Seed: 1)
2. Run /tp @s 0 320 0 0 -90 to reduce what is rendered
3. Wait for CPU usage to drop to about 5%
4. Run the following commands to start world generation

   /chunky center 10000 10000
   /chunky radius 1000
   /chunky start
   

Result

1.20.5

No effect.

without

1. 0:09:04
2. 0:09:02
3. 0:09:02

with Noisium 2.3.0 / Chunky 1.4.10

1. 0:09:02
2. 0:08:56
3. 0:08:57

1.20.4

Faster.

without

1. 0:09:16
2. 0:09:13
3. 0:09:15

with Noisium 2.3.0 / Chunky 1.3.146

1. 0:08:18
2. 0:08:20
3. 0:08:17

I also confirm that it is ineffective in 1.21.1 and effective in 1.20.1.

Hi, thanks for the detailed tests!
I've been meaning to set up a test bench to test futher optimisations, but I haven't gotten around to it.

I'll leave this issue open until I've explored various other optimisations and thoroughly tested them.

I see. Thanks for your reply!
