So i bought a second laptop to record with 2 Kinect v2's. No issue recording on my PC at a stable 30fps but my laptop hovers around 27-29fps.

The laptop specs:
Intel(R) Core(TM) i5-7300HQ CPU @ 2.50GHz (4 CPUs), ~2.5GHz (faster than PC)
8192MB RAM (PC has 16gb)
GTX 1050 2GB (Better than PC)

Only downside compared to my PC is the laptop doesn't have an SSD.

I've tried various tweaks to get it locked to 30, most from this forum. I've disabled integrated graphics card, enabled the dedicated graphics card for iPi Recorder. Disabled paging etc...

No budge in FPS. Any idea what the bottle neck is here?

Also is it possible to record even though the FPS is below 30 when using slaves? I just get the message saying it is below the recording target but 2-3 fps shouldnt give that much of a quality dip.

Hi
Did you try connecting Kinect to different USB ports?
As I understand, FPS is low before you even start recording, therefore is not writing to disk yet. Anyway, disk performance should not a problem with a single Kinect.
Difference in 2-3 fps between cameras may put a recording out of sync, so it won't be usable for tracking. Better to resolve the issue with frame rate.

Yes. I have 2 USB 3.0 ports both yield the same FPS.

What determines the outputted FPS? USB transfer speed? Graphical rendering? CPU? If the issue isn't the hard drives I can try to narrow it down further.

To my knowledge, Kinect frame rate may be impacted by USB issues or slow GPU (Kinect SDK uses GPU computations to some extent).
I recommend you to run Kinect Configuration Verifier tool, may be it will show what it does not like in you laptop. Download it from this page

OK, now please open Kinect SDK Browser (start typing Kinect in Start menu to find it). Then run "Depth Basics - D2D" sample. What FPS values does it show in the bottom-left corner?

...

Do you have your laptop power setting on high performance?

You can try minimizing the recorder on the slave computer to the task bar.

You don't need to see the actual recorder in the slave for it to be recording properly.

Just 2 suggestions you could try, hope it helps.
