[2020] Howto reduce Loading Times?

That does sound unusual, if the map really is generated already. If Navezgane also takes this long, we'd know for sure that it's not generation-related. I'd say load times are less than 30 seconds for me. If you post your specs, we could narrow down if your hardware is likely struggling or if it's something else.

For an 8k map, 20-25 minutes on that GPU is perfectly normal. They're working on speeding that up. Ideally they would prefer that it was under 5 minutes, and that you would be able to make up to 16k. There's still a lot of work being done on the RWG algorithms.

Originally posted by Power Button: the map generation for me is like 4 hours. Well, I play it on i3 with only 4 GB ram.

it's worth it.

Yeah, when you have no RAM, it's going to use your Pagefile on the really slow hard drive. That will make it take considerably longer. And if your GPU has less than 4GB VRAM, it's not even able to use that to boost the speed.

Originally posted by Blitz4: Loaded that map I generated ~8000 size, this time it took 1:02 to load. Pretty sure my cpu was pre-occupied, if I notice anything else strange I'll post it here.

That 1:02 sounds comparable to when I was playing on an i7-2600, though that was a few alphas ago. I'm glad you're doing better than 6 minutes now. As a reminder, there are three pregenerated maps included with the game for those that don't want to generate their own.

Uninstall. Reinstall. Yea I do that often. Doesn't fix the issue.

Dwarf Fortress takes just a bit longer unless it's tweaked it to not generate so much data. Difference being is that DF is single-threaded.

If they didn't update the game any more. I'd be stuck until I get a new CPU in 2 years. DF on the other hand, it'll forever be stuck on a single-thread and future updates will only make it take longer, no matter what CPU I get. There's worse things.

RWG generation uses the GPU. Assuming you meet the recommended spec of 4GB VRAM.

Originally posted by Blitz4: What I'd like is I could automate the process. Use some cli program to generate these worlds at night, then when I awake I could use them. I wonder if there's dedicated server software for this game and if it has some feature like that.

This ability partially exists in the vanilla client. Just use advanced generation. It'll make the map and then stop, so you aren't dropped into a save with the map. The only real limitation is that you can't batch it for multiple maps.
