Qt 3D Renderer changes and improvements in Qt 6
With Qt 6 well on its way, it’s about time we go over some of the internal changes and optimizations made to Qt 3D for the upcoming release.
In a separate article, my colleague Mike Krus has already highlighted the API changes we’ve made in Qt 3D for Qt 6. This post will dive into the internal changes.
Back in 5.14, we got rid of the Aspect Thread. Yet we still had a Render Thread. On paper, having a dedicated thread would allow you to send drawing commands to the GPU while preparing commands for the next frame. This could potentially help with maintaining a high frame rate, if command submission took a long time. In practice, this worked only in the case that Qt 3D was used as standalone (without QtQuick).
