I have buy several copy of Qcad pro 2.2, mainly my studio is doing architecture design. When using the Qcad pro, we found that if the drawing is over 1,000 lines in a file, the qcad is slow, when there are hatches and text, it will become much more slower. Even the opensouse Qcad 2.05 is faster than Qcad pro. At first I'm doubting that the Nvidia 2d driver on linux is such bad, but when I tested it on windows xp, it's the same. Even in draf mode, it's just speed up a little. Can you improve this in next generation? We really need it to do it better in some big project. By the way, how about some new about Qcad pro 3.0, when will you release it?
