what compression system is the game using?

looking at all different compression algorithms zstd is the best jack of all trade for size, speed, low overhead.

The compression is not the bottleneck in this game. Therefore, messing with it yields next to no gain.

[magitsu]

Saves are gzip, but the compression part is told to represent only a minor share of the whole process of writing the different gamestate parts first into memory and then into a savefile.

if u could shave of saving and loading time from 30 seconds to 10 seconds that would be great tho.
it seems like a simple fix rather than just multithread more bro

It's already improved that much from what it was. 6.0 beta load time once again seems to improve from the previous versions. We are just paying the price for more dlcs added or longer playtime saves.
Everything simple has been done hundred times over at this point.

OP, you don't seem to have read the previous replies. Compression and decompression form a negligible part of the saving and loading processes which, incidentally, are already multi-threaded. The way the threading works means that changing the compression algorithm would make approximately zero difference to the time.

Have you tried turning off compression for savegames in the game settings altogether? And did you see any significant differences in loading times?
Surely skipping compression altogether would have the least impact on performance, no?

[CBJ]

No. Again, threading means that it makes essentially no difference. That's why we've turned it on again by default for all those who had turned it off previously.

Here's Bernd describing how X TECH 5 and save/load process is improved with 6.0.

I get that but since X4 offers everyone to try out if there is a difference in a practical manner, they can see for themselves if their theory holds true. In case your word as a dev should not be trusted.

(And who knows, maybe it does make a difference in that particular case.)

(And who knows, maybe it does make a difference in that particular case.)

If it does it surely has to do with a specific machine or configuration. If that is the case, nobody would expect Egosoft to put any dev time into configuring for certain configurations (even for mine aged but into specs computer).

[Tamina]

yes

IF

What if change of compression algorithm can shave off only 0.00001 seconds? It seems to be so in X4.

Add to that that other people/programs do read the savegames too. Would you help them to switch
their algorithms?

Is there any way to disable the save compression in the new beta version?
