OSX version of Draftsight is very, very laggy. I'm using 13' Macbook Air (2013) and 21,5" imac (2014). The application is quite unusable on those machines - especially in fulscreen mode. Single window mode does not work as well. I've tried AutoCAD and it works just fine - buttery smooth. So i guess it's not a hardware problem. BTW Draftsight works great on my i7 PC. I would really like to use it on my Macbook the same was as on Windows. Unfortunately right now it runs in 10 down to 5 fps. :(

Any suggestions/solutions ?
