Dear All,
we are having problems with lag in one of our experiments. Each trial is a sequential presentation of 30 BMPs, each about 350 kB in size. A new BMP is displayed every second frame at 60 Hz refresh rate.
The problem: it lags. Every other second or so, more than two frames will pass until a new BMP is displayed. We are currently trying to get rid of some active processes in our Windows 7 installation to prevent the scheduler from interrupting Inquisit's runtime too often.
While doing that, I read the following here: http://www.millisecond.com/products/inquisit4/timing.aspx
Furthermore, Inquisit can minimize the chance that other programs, including Windows itself, will steal CPU cycles from it by setting its process and threads to the highest priority level.
How can Inquisit do that? Is it a built-in feature? Does it need to be activated?
Bye, Malte
