That 17.20 uses multithreads I have seen when performing DRC-checks.
But is the software in general written to make use of multi-core/thread CPU's?
Planning ahead, I see that less cores and high speed vs many cores and low speed are
the general options when purchasing new computers (unless you want to buy the "extreme"
versions of I7 or the most expenceive Xeons,)
I have also compared some certified CAD Graphic boards (Nvidia Quadro)
vs boards intended for gaming (Geforce GTX 6xx, etc). Both these families sometimes
exhibits erratic behavior when displaying certain colors/outlines properly in some zoom levels.
I filed a case with Cadence regarding the turning on and off of layers, that it did not happend
until the mouse pointer was back in the board display area. This has been confirmed to be a problem
when using the Windows "Classic" skin (like w95) Once changing to W7 "Aero" look, the problem
was gone. I have not yet upgraded to W10, so I would like to know if this problem is gone
in W10?
