I'm asking DRT for presentation times of 12ms and getting anything from 15 to 350. I'm running Windows 7 on a new Dell with a CRT monitor set to a refresh rate of 85hz. My video card is an nVidia GeForce 9300GE. I've read the previous posts on subliminal issues and they didn't solve my problem. For example, I've got a 1000 ms trial interval and on my display properties I've selected 85hz for the 1024 x 768 resolution I'm running the study on. It seems like my issue is quite similar to the last post on the subliminal "sticky" thread-- ssmith left the post:

I'd greatly appreciate any help anyone could offer on this issue...thanks!
