# Objective The UI text rendering is really slow because it extracts each glyph as a separate ui node even though all the glyphs in a text section have the same texture, color and clipping rects. ## Solution Store the glyphs in a seperate contiguous array, queue one transparent ui item per text section which has indices into the glyph array. ## Testing ```cargo run --example many_glyphs --release``` Runs at about 22fps on main and 95fps with this PR on my computer. I'll do some proper comparisons once I work out why tracy 11 is refusing to run. --------- Co-authored-by: Kristoffer Søholm <k.soeholm@gmail.com> |
