Demo vs Full Game (FPS difference)

[just___pizza]

I have the demo of KSP which i really like and am planning to get the full game really soon.

Here are my specs:

Intel i7-4720HQ
8 GB RAM
2GB Nvidia GTX 950M
Windows 10 (Home)
Display 1920x1080

On the demo, i get around 80 fps. What fps can i expect on the full game?

Also this fps is with 2 ships only around 60 parts each.

Will my game be playable with many ships?

Thanks!

I'm on a 2013 Macbook pro and I avg 60-100 sometimes more or less. It can be a huge demanding game but you can tweak graphic settings to suit your platform and get better fps.

Also, IMHO, Because of the way this game plays, I notice that I personally don't get bothered by frame drops. It's a slow paced casual game, not a twitch shooter.

(Console games are only 30-60 fps. Just something to think about)

yes i get what you are saying about the fps, but who doesnt like a smooth game. Thats all!

And btw i used to play the game a while back (the demo) on an older computer at 20 fps and it was still okay!

But the main reason im asking is that i upload to YouTube so i was looking to see what fps i can run at....

Thanks for your help!

Before you buy, play around with the graphics settings in the demo and see if you can find a combo that gives you the frames you're looking for

Also try recording and uploading a session of demo gameplay so you know what it looks like after you put it on youtube (as you probably know, video quality can change/look different after uploding it to youtube)

ok, i just rendered ou a vid and it will be on my channel soon...say in a day maybe. Luckily i was able to record at 60 fps perfectly.

The full game does seem to run smoother than the demo in my opinion. Part count though can drive down fps though. Things were pretty bad when I got this monstrosity together in my past career mode.

The clock/timer in the game gives a clue as to how it is running. When it's green, it's fine. Yellow means it's working. And red means it's struggling. Alt-F12, which brings up the cheat menu, has a tab that shows exact fps too.

I would say it depends on what version the demo is. I was under the impression it had been updated to a version of 1.0 KSP but a recent thread has me unsure.

If the demo is a 1.0 build, I would say you should expect better performance in the same situations.

If the demo is still 0.18 era, tough to say, testing showed it didn't perform too well by comparison to some of the other alpha builds but there could be anomolies due to how the test was performed.

It's not completely up to date but all you really need to know is the 1.1 update provided significant increases in performance with large part counts.

[Gianni1122]

I would assume that the demo version is probably 1.1
If you're going to show off your product to possible consumers, why show an old version?

I could of course be wrong

the bigger the craft the bigger the lag. it's not my computer that lags out, it's the game.

Highest challenge for your tech is probably airbraking 200+ part ship and starting time warp.
Another simple example is FPS doing a dive every time you decouple something - physics change, parts explode... it's all hard math.

Nothing changes in game starting warp, but your processor fails at some point.
Game is a script, an algorithm. It can not lag. Computer executes it. Leaks may cause less memory and thus more lag, but I haven't noticed memory leaks in vanilla game playing for 10h. Even if there are, they wouldn't be significant.

So it is the craft and flight specifics (total amount of "physics"). And simulation speed that overloads your PC.

i usually lag out at about ~450 parts in atmosphere and 525 in deep space.
