Dear List, I've tried just about everything to solve this problem with no luck, so I was hoping if the list had any ideas. Basically I have two parallel loops running (Event Loop and IMAQ Display loop), however every now and then when I click on the IMAQ window to draw an ROI on the front panel the program will pause for 4 or 5 seconds and then carry on, it is really, really annoying. I have an almost identical system running with a NVIDIA GeForce4 MX440 AGP Card (both systems are Windows XP with LabVIEW 6.1) and this does not occur. I have tried the following: 1) Updated the driver to the latest version for the ATI Radeon 9200 SE. 2) Made sure there is a Wait State in the IMAQ Display Loop. 3) Adjusted Various Performance Settings (Processor Scheduling and adjusted Visual effects for best performance). 4) Adjusted the Hardware Acceleration from Full to None. My last option is to swap the AGP cards around, but I'm hoping there is an easier solution.
