Obsidian 14.15 (latest) is actually 100-130 Elo weaker than Stockfish.
How, seriously how did you come up with that number?

version 14.14 was used in the first half, but now 14.16 is doing the work and LC0 is breaking away. :)

We got it!
Here is a bash script to compile Obsidian:

https://poe.com/s/YjrrIddTwdaIVjOjUeV0

It's similar to the one here for Stockfish:

You need to install MSYS2 first as explained here:

https://github.com/official-stockfish/S ... -installer

What is this speedup meaning?

Use network weights directly from the exe

>python bench_engine.py -S 1 -T 8 -E Obsidian_old.exe
Speed for Obsidian_old.exe is 1420187

>python bench_engine.py -S 1 -T 8 -E Obsidian.exe
Speed for Obsidian.exe is 1786090

Should give some elo?!

Ignore him, he is always complaining about things not working for him. It is not the first time he complains.
