I really apologize to everyone when I pull it again. But I would like to understand the principle of work of Corel and/or if it happens only to me.I gave advice on upgrading graphics, new card is nVidia Geforce GTX750Ti 2GB DDR5 RAM, 128bit. While I know that in 2D applications such as CorelDraw graphics card is secondary, just I would like to return to this topic. No one met a similar mess on the monitor as I do? It is not only issue of bigger or complex files at all. Time response is a part of smaller files too. Once again send screenshots of the same file http://imgur.com/GGkhsuQ - before screen panning and during http://imgur.com/CpqUaf6Perhaps nobody doesn't work with Corel on similar projects? I don't believe that. So I was pretty upset. I'm looking everywhere for a satisfactory explanation, cannot find anything. Maybe my poor English to explain the problem is the reason of unclosed topic (for me). Who will be kindly to tell something, I welcome any idea or experience. Before closing this discussion I have this last question. Even if Illustrator don't have similar problem. I don't want to migrate to another software, I'm tired of change. Corel is my long-term concern ;-). Maybe it would be corrected by the new version? What about this?Thanks for reactions.Peter
