Speedy Painter is an OpenGL-based paint software. It will only work if your graphics card supports OpenGL 3.0 (which will almost certainly be supported unless your hardware is older than 6 years).
Features include:
- Layers
- Rich brush engine
- Size and opacity of brush strokes determined by pen pressure
- Selection mask
- Reference view to assist in creating a painting based on a reference image.
- Perspective grid overlay
- Replay of paint process
- Export of paint process into a AVI video file
