Dear Greg-H,

I updated some figure files. Please look at it.

Hi,

Can are you installing these two OS versions on the same computer with a hard drive partition or is it two different computers?  Also, the acquisition is being done with LabWindows CVI how you getting this data to computation software?  Lastly, are you saving the images or doing any other processing or just acquiring the images?

Regards,

Greg H.

Dear Greg-H,

I did a hard drive partition with similar capacity not different computer. 

Yes. I am using LabWinddows CVI for compile C programing after that, I just use that C programing.

This program will acquire image and save image in the hard drive.

Dear Greg-H,

Did you get any result with testing?

Hi,

I thought I had posted some possible reasons for this behavior last week, but it doesn't appear to be here.

First using a partitioned hard drive will make things operate differently.  Since you are using a 64-bit OS then it is a 64-Bit machine.  There is extra processing done in the background to emulate a 32-bit environment when running the 32-bit OS.  This will also occur when running a 32-bit program (LabWIndows/CVI) on a 64-bit machine and OS.  Also when the hard drive is partitioned the read and write functions for file I/O can take longer.  I would suggest trying two things.  First, try the acquisition on a hard drive that is not partitioned.  Secondly, remove the file I/O functionality and see if the frame rate is more stable.

Regards,

Dear Tayoon Lee,

I'm experiencing similar problem with my application (the application grabs images from camera and runs some processing on them - using matrox card). The application runs just fine on XP but has unstable rate on Win7 OS (both 32 and 64).

Did you find the reason for the instability you experienced? was it solved?

thanks,

Hi h,

We could not solve this problem yet. So, we switched back to Windows XP for live cell imaging. But, we are using for fixed cell imaging with Windows 7 64bit.
