Minecraft alpha 1.2.6 lags when loading new chunks. Anyway to tone down the lag

minecraft-java-edition

Recently I've noticed that when I'm loading new chunks in minecraft alpha 1.2.6, it lags. Since this is an old version, there might not be a way to combat this, but if there is, how can I tone down the lag? I have 4G RAM and the latest version of Java. My memory usage is at about 20-25%. Also, I normally get about 60FPS in small window mode. (I just like small window better.)

How can I tone down the lag?

You can do the classic "allocate more RAM" mixed with a NORMAL or SHORT render distance. That way the game will load a small number of chunks at the time.

Just set -Xmx to the maximum RAM that you want to allocate for the game. As an example:

-Xmx512M # 512MB
-Xmx2G # 2GB

Launch Parameters

As far as I know, there is no OptiFine version available for Alphas, Betas or Snapshots.

Since this is an old version...

Yep, I did some testing with Alpha 1.2.6, Beta 1.5 and Release 1.12.2 and even my "light gaming capable" PC struggled to keep up. Looks like this version is not optimized for recent PCs.

This is my benchmark of the Alpha 1.2.6 (old_alpha a1.2.6):

Average framerate  :   70.1 FPS
Minimum framerate  :   19.7 FPS
Maximum framerate  :  122.9 FPS
1% low framerate   :    4.1 FPS
0.1% low framerate :    3.0 FPS

Just in case, a benchmark of the Beta 1.5 (old_beta b1.5):

Average framerate  :   81.2 FPS
Minimum framerate  :   39.6 FPS
Maximum framerate  :  157.7 FPS
1% low framerate   :   15.1 FPS
0.1% low framerate :   5.6 FPS

And a more recent game version, Release 1.12.2

Average framerate  :  126.5 FPS
Minimum framerate  :   43.8 FPS
Maximum framerate  :  222.9 FPS
1% low framerate   :   27.9 FPS
0.1% low framerate :   16.2 FPS

All of them used the same world and graphics settings (medium render distance and fast graphics preset) plus none of them were modified. The resolution used was 1366x768.
