Hi, What you are maybe looking for is this option that was available in QGIS 2.18 and 3.4 : https://download.qgis.org/qgisdata/QGIS-Documentation-2.18/live/html/en/docs/user_manual/print_composer/composer_items/composer_map.html Render mode : rectangle, cache, render.
Maybe it has been removed with the more powerful computer arising ? Best Regards, Jérémie.
