Phone freezes / stops / very slow after opening offline maps

Not sure, but it seems that there is a technical issue that roads are rendered too thick on @Teun’s device? The regular Kurviger map rendering is thicker roads compared to the default VTM theme to make it easy to identify roads during navigation.

The netherlands map seems to be very demanding on the device.
There my phone also slows down to a frame rate of ~2-3 fps (with vegetation on).

And even the menue becomes slow when I view netherlands.map
Turning vegetation off makes a big difference here.

@Teun try panning around in the south German/Austrian area :wink:

BTW
Netherlands at similar zoom level as above looks “normal” here

That could be, since it’s not a normal roads rendering, like demonstrated above for same screen DPI.

Several OEMs offer display modify options of resolution / dpi / etc. that can make the rendering worse.

Would be interesting if there are users with similar large screen resolutions to post some screenshots.
e.g. 1440 x 3040 pixels

:astonished: It doesn’t recover to normal rendering, when resolution is set back to FHD

Edit:
Rebooting the phone restored the rendering to normal

This will help: I just discovered that I only get the thick roads when increasing resolution from lower to 3040 WITHOUT restarting the app. When I close and restart Kurviger, it looks normal again. Sorry if I caused confusion.

Indeed restarting the device and / or the applications after making such core changes in Android settings is often the easiest way to make sure that everything is initialized again with the new settings.

Sorry, I do not see that to be an answer, or probably i am just lacking some basic understanding to understand. I will rephrase my question a bit below, maybe that helps?

I use same downloaded maps in K and Cr (not GL) and I think the Cr look and speed is superior to the way K is handling these maps. So why can K not do the same as Cr (not GL) ?

Thx

Cruiser cannot be faster than Cruiser GL, only “appears” in specific area / zoom / test.
Software rendering can never be faster than OpenGL hardware accelerated rendering.

More an illusion because of the heavy nature polygons in the specific DE & NL areas.
That’s why there is option to turn off Vegetation layer if users find it difficult in devices.

Cruiser GL platform offers map rotation / tilt, smooth scaling, improved labeling, etc.
Some are essential for navigation, users will start asking why any of them is missing.

Map appearance is something subjective, some may like it, other may not.
That’s a subject for a different topic, like ideas to improve map colors, etc.

I am comparing Cruiser and Kurviger here, not Cruiser and Cruiser GL. Still would appreciate an asnwer on that.

Wrt Cruiser CL: it totally not runs on my phone. It freezes and makes my phone crash. Definately not “appears”. Find someone with a S10 and try :slight_smile:

Kurviger is based on Cruiser (GL) platform, cannot say anything more on that.

Then can disable Vegetation layer for those heavy maps (as proposed above).

By the way Kurviger 1.11.8 (Beta) solved that, (Cruiser GL is not yet updated).

I could try further offline map rendering improvements, but need detailed feedback for current situation.

Testing Germany & Netherlands maps, since they have numerous heavy complicated nature polygons.

@Teun and everyone else:
Which zoom levels from 8-9-10-11 have still problems with Kurviger 1.11.6 (Beta)?
Can you post details for each zoom level, to see how each one can be improved?

Please take the fps rates with a grain of salt, as I’ve estimated them, and the performance is not constant either.
But the zoom level thresholds should be very close :thinking:

Pretty frustrating this. I do not understand your explanation and have the feeling that I am just not getting an answer to a direct question. I appear to miss some basic information which is obvious to you, or something, I don’t know. I will stop discussing this now. I will use Cruiser (not GL) for importing gpx files and I will enjoy the more beautiful and faster offline map experience. Hopefully you will not change that with an update.

As said, after restarting the app the very thick lines are now less thick and the yerkiness of map and menu on 3040 is not great but acceptable.

I had to wait 53 min to be able to post this reply, because I hit the daily quotum for a new user its says. Pfff!

Enjoy your driving, don’t watch the gps too much :slight_smile: Speak to you later maybe. Teun

Very nice of you to accept this Teun, and thanks a LOT for all the details. I think we can all agree that your posts were not spam :wink: the daily quota is a feature of the forum software in general and nothing against you :smiley:

What was the exact question? :slightly_smiling_face:
Why Kurviger is based on Cruiser GL platform and not on Cruiser platform instead?
That was the design from the start, because of the many GL features / advantages.
It’s like asking why we don’t prefer Google Maps or Mapbox map engines software.

Kurviger 1.11.7 (Beta) contains a final set of offline maps rendering improvements for even faster performance.

Solved in Kurviger 1.11.9.
