We released 0.18.4 this week, same old same old, more bugfixes, more bugs, more changes. At this stage of development, not many interesting things are happening, we are just polishing what we have.

Minor terrain render optimization posila

Just a couple days before the release of 0.18.0 I had an epiphany about a terrain rendering problem that was bugging me for a really long time. When rendering terrain, we reuse the texture from the previous frame. How this was always done, is that we would render the texture shifted to the new position, fill up the gap, and then copy the final result back into the texture for reuse in next frame. So what was bugging me about this? This simple operation would result in rasterizing 2 screens worth of pixels. While that is not a problem for at least half decent GPUs from the past decade, it's a significant work load for integrated GPUs, which in general have an order of magnitude lower memory bandwidth than dedicated ...
