I could not find the system recommendation on Tobii website. What would be the ideal configuration for an X120 and Tobii Studio ? We are planning to buy a desktop computer, not a laptop.

Hi Marion,The upgrade fr the X120 is done the same way as for the T120. You are welcome to contact us at support@tobii.com to schedule a time for this.Nicolas: we have identified this as a bug in the eye tracker firmware, in some cases calibrating/recalibrating in 120Hz can cause crashes. We have a fix for this that will be released shortly.Joakim
