End users have been noticing for ArcGIS 10.1 on Windows 7 that ArcMap periodically suffers more from graphic user interface rendering latencies relative to version 9.3 even when the hardware requirements are exceeded and 32 / 64 bit processing is available.
Misc. reference documents:
I have not noticed any documentation on setting ~preemptive processing rights but if that is not already implemented it might be something to do to enhance ArcMap GUI performance..?
This type of issue is very significant since it seems that with each new version of the software basic functionality such as responce time, etc. is getting lost.
