camera very slow in labview not MAX

[real_dufus]

I am running a firewire camera in Labview on Xeon machines.  In MAX I get my 200 fps. I am running this on 3 machines. 

On one machine Labview runs as expected at 200fps/

On another machine it starts at 60 fps and then sometimes goes up to the 200fps.

More worrying on my last machine it starts at 50fps and then slows down sometimes to 5fps. 

The ode is identical and on all three machines I get 200fps in MAX.

Any ideas?

Thanks!

Hi,

To solve this mystery we need some additional information’s.

So you have 3 exact same PC’s and 3 exact same camera’s running the same Program but you experience different results?

Do you use any other additional hardware/peripherie?

Is the Firewire directly connected to the main board or do you use a PCI or PCIe Card?

How do you acquire the camera data in LabVIEW?

Hi, thanks for the reply.   The three computers are exactly the same and run the same labview program connected to the same firewire card (pciX).  The computers have different other software installed (which is not running when Labview is  - check this with task manager).  I am using IMAQdx vis.

Anti-Virus or Firewall software running?  I've seen odd things happen to cameras because of that, but I would expect it to be on all PCs.

the framerate is heavily connected to the MAX settings like exposure time. to be sure to use the same MAX settings on all machines you can export and import the settings. It would also be interesting to monitor the CPU / RAM load with the task manager when the fps drop.
