Global Mapper v25.0

GM18 digitizing latency

kopa Global Mapper User

compared to the prior versions is feature digitizing in GM18 not very fluent. There ist a huge latency in the rendering, independent if there are other layers loaded or not. Is there somewhere a setting to improve this?

Best regards,

    Hello Fabian,

    Are you having problems in the main 2D view, or in the 3D Viewer?

    First, I recommend trying the most recent daily build . Simply download the appropriate installer and run it to install the latest build.  We have been fixing some bugs and performance issues since the release of version 18.0.

    If you are still having problems, please send an e-mail describing your workflow and the results, with a copy of your sample data, to Blue Marble Geographics support (  This will ensure that the support team sees the problem and can provide you with a timely response.  Thank you.
