RE: Orcad Capture - Slow Graphics response on windows 10

Well in a way you have confirmed that I was not loosing my mind. I did a little more digging on this and here is what I found. I ran a windows "Proc Trace" on capture as it loads on windows 10. The trace showed that every .tcl module getting called by capture has "Buffer OverFlow issues " In addition when capture is installed on windows 10 the installer tries to install .net 4.5 but .net 4.5 is not really supported anymore in windows 10 because .net 4.6/7 is part of the windows 10 operating system. You would need .net 4.5 if installing on win7/win server so perhaps the installer is just a bit out of date. The fall creators addition on my system proved to be the turning point on capture for me. Capture is not very usable. 2d acceleration on the capture IDE does not seem to work. I found drawing on the canvas to be ok but all in all capture is no where near as fast running on win 10 as it is on windows server 2008. I found no graphic related issues running the PCB tools, Graphics on win 10 with allegro/orcad pcb perform really well. I also did a proc trace on allegro as it was loading and found no "Buffer Overflow issues" I checked CM in allegro and didn't notice anything strange but will check again. I found today that MS has issued a patch to the 1709 ver of win 10 that addresses slow graphics in the edge browser among other things. I will update to the latest win 10 that includes this recent patch and see how capture works. Thanks Paul.
