I am running DirectRT version 2010.3.0.109 on Windows 7 64bit and am getting the following error:
"DirectRT can not determine your display's refresh rate which is critical for accurate timing. The cause of this problem is usually an outdated or disabled video driver, or disabled hardware acceleration in your video settings. If you needs help resolving this issue please report this error to suport@empirisoft.com. Error #6. Overflow"
This same error occurs on numerous machines with various versions of 2010. All drivers are up-to-date.
If I force the refresh rate to 75hertz I have had some luck making the program run. However, after running the program 1-3 times the refresh rate resets to 60hertz and the programs throws the error again. Since this fix doesn't work 100% of the time I need better solution before I can offer DirectRT to our users.
Attached is a DxDiag export from one of the machines along the error msg.
I emailed this to the support email last week and have not yet heard back.
