"Max physics delta-time per frame" effects & physics-related FPS drops

[Wampa842]

Recently my space station has reached the upper limit of my computer's performance. It's fine when I time-warp (physics disabled), but it becomes an FPS-less nightmare when I want to manage my station.

Physics delta-time/frame has been set to 0.15 ever since I started playing to countermeasure my computer's bad performance, but it no longer seems to work because of the immense (relatively talking) amount of parts. Increasing it to 0.30 nearly doubled my framerate, but I'm too afraid of the consequences (decreased joint stiffness and stability, possible Kraken attacks) to fly my crafts.

While I know there's no other way to counter physics-related framerate drops (I wish for someone to tell me there is) other than upgrading my PC, I would like to know what consequences my kerbals will suffer from increased physics delta-time/frame.

My computer is running on:

AMD Phenom II x2 555 CPU (dual core, 3.2 GHz)

4 GB of DDR3 memory

This is what I can remember at the moment, I will provide other information if needed.

I can't help you with that particular question, but just so you know, .23 is planned to include a significant performance improvement.

Move your delta-time per frame to the far right, 0.03. It'll make your game move in slow motion, rather than lagging.

You could also try the WeldIt mod which significantly reduces your part counts. http://forum.kerbalspaceprogram.com/threads/38577-0-22-UbioZur-Welding-Ltd-2-0-Playtest-3-Now-In-Game-Tool

What exactly does that option do?

[Cruzan]

I haven't personally used it, but from what I can tell it takes any number of parts you want, and makes them only count as one part. This drastically reduces the amount of physics calculations your comp needs to do. You could probably find better/more info from the people who use it in that thread that I linked

There's a video on there of a guy whose design went from 1000+ parts down to under 50. Pretty crazy! Useful for stations and stuff I would imagine.

A good thing to let us know is how many parts your ships have, you may not be lagging any more then the rest of us!

Look to the quote from Johnno. But I usually play with the slider at 0.10, so if you are running at 0.15 thats good. Hope I helped somehow
