I have a 4cm resolution drone-derived image GeoTIFF that I am displaying in QGIS. The image is approx 600mb, I have a compressed version (BIGTIFF=YES, TILED=YES) approx 250mb. Both when loaded into QGIS (3.20) take a very long time to load.
Is there a simple way to speed this up? For example, if I load the KML version (128mb) into Google Earth, it's renders almost immediately.
