I have noticed the same problem.
My PC is normal but the project opening/closing operations, Library managing etc.etc. seems too slow.
I don't know any solution, but if there is someone who knows how to speed up PADS I am ready to apply the advice.
I'm on Windows 7, which may make other issues...
As I'm a new user, I don't know if my experience is normal or if I just have some settings wrong. Basically though I find a lot of latency for many normal commands and tasks that I feel should be instantaneous. It feels like I'm working on a PC limited by ram or something like that (or maybe a mouse clicker stuck in glue...), but this one has 16 gb and the graphics card is ok as well (nothing special, but it feels fairly speedy in other programs). I mean I can upgrade the hardware, but if everybody's experience is like this then there isn't much point.
I'm going to install the latest update (7), maybe this will improve things...
I am working with WIN10 and Vx.2.2 Update 7, and PADS is very slow as well. I don't know why.
I tried to install version VX.2.3 and I have to say that the launching time of xDX and LAYOUT has worsened.
With VX2.3 it takes more than 60 seconds to open LAYOUT from xDX while with the old VX.2.2 it took about 10...15 seconds.
I have a workstation with Win10pro, I7 CPU, 16GB RAM and SSD: I do not understand why only PADS VX should be so slow on my PC.
