Well - from my use case I consider it ready. But there's some outstanding questions which need solving (see the PR discussion): - should this be normal behavior? - should it be enabled for all layer types? wmts only (as per sourcepole's original implementation)? local layers only (for those of us on crap/expensive internet connections)? rasters only? vectors only? - is the cpu utilisation for rendering these possibly unseen tiles an issue? or is cpu use so cheap nowdays that it's not a factor? - should the rendering of the adjacent tiles only begin when a pan starts? (would lose the zoom out benefits this brings, plus add a delay in showing the nearby area when pan starts) My 2c: just enable it for everything and let everyone get the benefits without any configuration hassle. But... all my workstations are at least 4 cores and lots of memory. So I'm probably not in the best position to make this call ;) Nyall _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
