Almost unusable due to lag

#1 Post by jstkruzen » 29 Jan 2023, 09:12

Hi All,

Running version 4.3.0.4. Doing a project with a board size of 100x100mm with ~220 components.

I have almost unusable lag with DipTrace right now. My rig isn't blazing fast by all means but it should be ample.

My rig:
GPU: 3060
Ram: 32GB
CPU: Ryzen 5 2600

Any suggestions?

Thank you

Alex

Thank you for the report.
Do the lags happen with specific only or any board design? In the first case, please send board file to DipTrace support for verification or upload it on the forum.

CPU: Ryzen 5 2600->AMD EPYC 9654
Ram: 32GB? What speed?
GPU: 3060->Nvidia RTX 4090
Looks like a two or three year old machine.
A $12,000 CPU with a $2,300 GPU plus a motherboard should speed it up

Hi Alex,

Thank you for your response. It wasn't an issue until recently (no changes in hardware or software).

It's on most my boards except a few slightly smaller ones.

I can still send over a copy if that would help.

Yeah, I'm also finding 4.3.0.4 EXTREMELY laggy.

For example:
* when I click the 'Route Manual' button it takes about 2 seconds for the UI to become responsive again.
* Starting to route, then pressing ESCAPE to cancel routing takes about 1 second
* bringing up the context menu takes about a second.
* pressing alt-tab to switch FROMthe app to another app (e.g. to reference a datasheet) causes a lag.


I tried the different rendering modes:
* Windows GDI - laughably slow.
* Direct3D - faster, but way worse than 4.1.x, noticably slow when zooming using the mouse-wheel.
* OpenGL - best, but way worse than 4.1.x.


My system is a 32-core AMD X5950 with 64GB of RAM and an NVidia 4090.

I used diptrace/example/pcb6 with shape router free.dip and pcb6.dip 133 patterns as a test since everything I do is less than 50X50mm.
With an i5 9th Gen, 16GB, Nvidia Quadro there is no lag in PCB view or 3D view, I only use OpenGL. For routing and switching screens it is instant, no lag.
Is there a large test file/pcb we can share somewhere besides the example folder?

I finally figured it out. It's the copper pours that cause the lag. My board is 100x75mm with 2 pour layers. Any ideas?

Have since upgraded to:

CPU: Ryzen 7 5700x
GPU: 3060
RAM: 64GB @ 3400 mhz

On MacOS, people have noticed that turning off display of what layers they can - reduces lag.

That may also work on Windows platforms.

Other people have reported "hitting a wall" where adding just a little extra content to the PCB seems to result in a significant slowing-down.

Even just un-pouring your copper pours may help.
