ArchiCAD 20, slow to load, sluggish in 3d

bgoodale — Thu, 11 Aug 2016 20:32:14 GMT

Im finding archicad 20 very slow to load even small files, and the performance in 3d open gl is sluggish to the point of being nearly unusable in 3d. and i have a pretty good machine:
HP Zbook 17
32 gb ram
intel Core i7 @2.8ghz

I too have a z-book (refer signature) but am finding AC20 as fast as AC19, could be file related

it seems to be be independent of the file or file size...

Check your Build number. Your signature says 4011. I am quite sure there is an update. We were having a similar problem with one of the updates in ArchiCAD 19.

Hi Bgoodale. Please update your signature! Are you using the 3016 ARCHICAD 20 Update? If so and AC20 is still slow for you, please let me know and I will request the file! Thanks, k

I am having the same problems. Just loaded up Archicad 20 today for the first time and 3d is barely usable. Loading time did not seem to be an issue but I have the same exact file opened in Archicad 19 and Archicad 20 and the difference is significant when moving around in 3d space.

Attached is the GPU usage charts from both programs just rotating around in 3d its seems that Archicad 20 is not fully utilizing my GPU. Not sure if this is the issue or if this is a result of something else that is causing the problem.

I will run additional tests on the other office machines when time allows. As it stands now, I cannot migrate my projects to AC 20 with this drop in performance.

Ok I just figured out the issue.

I was using the PotoRenderings Setting Background Image setting. Using an Image in AC20 drastically reduces performance. As soon as i switched the image off, performance came back to normal. This is not the case in AC19

Graphic Card is able to use 100% GPU also.

I can work without the Background Image but it would be great if we could fix this. Another option would be to have gradients for the background color instead of solid colors. Sketchup for examples uses very nice gradients for their 3d visualization.

I send snapshots of the 3d window all the time to clients, gcs etc. Therefore i need the view to be as appealing as possible. This is not used for presentation drawings but for the day to day communication.
