Part count to lag?

[Scottiths]

Just a general question, but at what part counts do you tend to being lagging and at what point is it almost unplayable?

I start lagging at about 180 parts and when I hit 250 it starts getting to the point where I am better off letting mechjeb do my 3 minute maneuver burns and coming back in 15 minutes when they are done.

For the curious:

Windows 7 64bit

Intel Core 2 2.66GHz

4gigs ram

Nvidia 8800 GTS

As a side note I have not updated my computer in any way in the last 5 years, so I consider 180 parts to be pretty good considering. If I were to consider new specs, what should I do to get the best KSP experience?

[FITorion]

I start getting laggy around 1000 parts. I haven't gone much past that in a single ship to see where it becomes unplayable. I wouldn't want to try docking at the 1000 part point... but I think I could...

Intel Core i7 3.20 GHz

32 GB ram

Windows 7 64 bit

Nvidia GeForce GTX 680

I tried making a town... It's really laggy... all buildings together and the road are probably about 1200-1400 parts.

Edit to add:

OH man ALL my posts are gone! I expected some loss due to the forum reset... but everything? I even lost my one reputation up vote ;_;

1000? That's presumably with the physics slow down turned on rather than realtime.

[FITorion]

No. That's without any sort of modification to any setting other than setting the graphics to maximum.

I start hitting a physics slow down at about 400ish parts, I've docked with stations where the total was 1,000 + parts though.

get it to start lagging at 650 or so. makes a second last about 2.5 seconds. all settings maxed no adjustments.

About 500 for me as well.

My machine.

It doesn't do much good if you have more than about 6 GB of memory, even if you have a 64 bit OS, as KSP is a 32 bit program and isn't coded to address more than ~4GB.

Sounds like I need to upgrade my processor as I am at about half what all you guys are able to pull off

[HoY]

There's no "best ksp experience" computer currently. Until they do some optimizing the game is always going to be the bottleneck. Running an i7 [email protected] with 32gigs and a gtx Titan I barely get better than someone with half of each of those.. That being said, in nvidia terms anything over a 580 will let you run ksp at max settings, the CPU does 99% of the work currently so focus on upgrading that!

I drop below 23 FPS at 150 parts with an i7 920, 18gb ram and GTX 460

[syfyguy64]

70-100 is my limit.

If you're experiencing bad framerate but are sure your machine can handle it graphically, try going into settings and moving the physics delta-time slider to the right. It will increase framerate at the cost of slowing down the simulation/not running it in real time.

[Sir Nahme]

I start getting slow down at 350 parts. I hit 3 fps at 788

[Scottiths]

My machine handles the graphics just fine. My processor doors not. I need the physics delta time at .5 to avoid choppy
