Recording

[xrayfishx]

I would really like to record some of the stuff I do, but on my heavily modded install (see signature) KSP starts to lag like hell when I start recording. The frame rate drops to about 5-9 and when I alt-tab out, I can't get back in and have to close the game. This is really shameful considering I have 3 unused CPUs, each running at 1.9GHz and supposedly are boosted to up to 2.8GHz when needed. Is there a way to make the recording software only use those 3 CPUs and stay away from the one that KSP is using? Right now I used FRAPS and in Task Manager I used the "Set Affinity" thing to only allow it to run on 3 CPUs, at first I tried disabling CPU 0 and then CPU 3 but neither option seemed to affect the game's performance.

So how do I go about this? What software to use, how to limit it to 3 CPUs?

Could it be that it's more about GPU than CPU?

Also, I almost forgot, the specs, in case they're important (though I don't get why they should be).

CPU: AMD A8-4500M

GPU: AMD Radeon 7670M + Radeon 7640G Dual graphics

RAM: 8Gb

OS: Win7 64bit

KSP 0.24.2 64bit

I suggest getting Dxtory,it uses less CPU but if not try removing mods you wont use or wont use much.

I recommend Open Broadcaster Software, which is free and seems to work quite well even with lots of mods. Not only does it record, it lets you stream.

I'd say, form my experience, if FRAPS laggs the game while recording, dxtory will lagg the recorded video instead. But then again, if anything laggs for me that isn't because of the same reson as for you, as your CPU is way weaker. OBS should work fine though. And unlike dxtory and fraps it's free.

OBS seems to work perfectly, there doesn't seem to be a frame rate drop at all and the video quality seems to be good. Thanks a lot.

... lag like hell...frame rate drops to about 5-9

Sorry to burst your bubble, but 5-9 frames per second is not lagging like hell.

5-9 seconds per frame, *is*

And many of my better worse ship designs do that.

Bandicam records it just fine, even at >3 seconds per frame.

It may resemble a slideshow, but....

when I alt-tab out, I can't get back in and have to close the game

First window the screen (alt-enter), *then* leave it by mousing outside, not alt-tabbing.

Alt-tabbing out from a fullscreen tries to reset the graphics driver instance, and will in any case do horrors to your recording session.

Is there a way to make the recording software only use those 3 CPUs and stay away from the one that KSP is using

Well, you could in Task Manager play around with the Process of the recorder, and fiddle it's "Set Affinity".

This will work like a bomb.

i.e..... it may well blow up in your face! But it is worth trying.

5-9 fps for a rocket that normally gives me 30 is lagging like hell.

I keep my designs realistic (I use RO) so I don't build anything that runs at 5-9 spf. Or even 5-9 fps when not recording.

There used to be a time when I also made huge ships so don't come telling me I don't know what low frame rates are.

I'll remember that.

I did that and I mentioned it in the OP. However, as I was told on other forums, most recording tools work more with GPU than CPU.

Whenever you upgrade get an nvidia card. Shadowplay lets me have 60 FPS 1080p videos on my 450 dollar budget build. Usually it records 60 FPS and I get 45ish.
