- A still card costs nothing: it redraws only when it moves or changes. 50 cards with text at 1920 x 1080 draw in
about 3 ms per frame on a desktop GPU.
- Text textures: each card with text holds one, about 1.4 MB at Text Resolution 512 (50 cards: about 70 MB). Try
256 for small cards (about 0.35 MB).
- Pictures: 1024–2048 px tall is plenty. Card textures are never streamed, so very large art costs memory while
loaded.
- Layers: up to 8 picture layers and two finishes; every layer with art is drawn. Switch off slots you don't need.
- 3D cards are see-through quads: many overlapping ones cost more than the same number side by side.
