Some thaughts about 17.20...

UlfK

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?

    I use 17.2 on Windows 10 64 bit with NVidia GeForce GT 650M. This is a laptop and the Intel HD Graphics card is still active somehow, but it seems like the Nvidia is in control. I never saw any issues with colors not changing until the cursor is in the screen area, even with Win7 and 16.2 up.

    The new Color Dialog changes the colors instantly but if you close the dialog without applying or using OK it reverts to what it was before. That and the new Visibility features make it pretty easy to navigate the many planes and regions.
