 /* Default size for the buffer holding the vertices and the indices.
  * A bigger buffer helps reducing the number of draw calls but may
  * waste memory.
+ * 1MB was picked because a lower value reduces viewperf snx tests
+ * performance but larger values cause high VRAM usage (because
+ * larger buffers will be shared by more display lists which reduces
