All demos were opened with Godot 4.2.1, with the mesh format
upgraded for 3D demos.
The 3D antialiasing demo now uses Extra Cull Margin on the last
object to prevent it from disappearing too early when the camera
rotates (due to its use of shader-based animation).
- Enable anisotropic filtering in 3D demos, and set the quality to
16× on desktop and 4× on mobile.
- Enable 4× MSAA on some 3D demos that didn't use it beforehand.
- On GLES3 demos, disable MSAA on mobile as these demos are often
more demanding.
- Use more conservative framebuffer allocation settings for better
performance.
- Use PCF13 shadow filtering in GLES2 demos on desktop to benefit
from soft shadows in Godot 3.2.4 and later.
In Godot 3.2.3, this will make shadows smoother but still "blocky".
- Use Lossless compression instead of VRAM compression for
small textures such as the voxel demo texture atlas.
