Introduction
GraphicTest is simple program which measure FPS of various direct drawing methods. Aim is to determine fastest method how to copy custom off screen bitmap to visible area on screen.
Listed benchmarks results are dependent on:
- computer hardware
- compiler optimizations
- operating system
- display color depth
- used GUI toolkit
- vertical sync and max FPS limit
In some methods it is necessary to do swapping B a R component of color in some platforms which results to better/worst test score.
Test 1
Hardware: AMD Turion X2 1,8 GHz, 2 GB RAM, HD2400
OS: Ubuntu 12.10, GNU/Linux kernel 3.5.0 i686, Gtk2
| Method | FPS | Frame duration [ms] |
|---|---|---|
| TBitmap.Canvas.Pixels | 1 | 1031.7 |
| TBitmap.Canvas.Pixels Update locking | 3.2 | 308.1 |
| TLazIntfImage.Colors copy | 54.3 | 18.4 |
| TLazIntfImage.Colors no copy | 64.4 | 15.5 |
| TBitmap.RawImage.Data | 102.2 | 9.8 |
| TBitmap.RawImage.Data PaintBox | 102.5 | 9.8 |
| TBitmap.RawImage.Data Move | 116 | 8.6 |
| TBGRABitmap PaintBox | 123.1 | 8.1 |
| TGR32Image | 68.5 | 14.6 |
| OpenGL | 56.7 | 17.6 |
| OpenGL PBO | 152.4 | 6.6 |
| Dummy | 38166.3 | 0 |
Conclusion the faster method with a good video card:
1) OpenGL PBO
2) TBGRABitmap PaintBox
Test 2
Hardware: Intel Celeron CPU 2.66 GHz, 1.50 GB RAM, NVIDIA GeForce 6200.
OS: Windows 7 x86.
| Method | FPS | Duration |
|---|---|---|
| TBitmap.Canvas.Pixels | 1.44 | 694.82 |
| TBitmap.Canvas.Pixels Update locking | 7.81 | 128.07 |
| TLazIntfImage.Colors copy | 96.6 | 10.35 |
| TLazIntfImage.Colors no copy | 96.7 | 10.34 |
| TBitmap.RawImage.Data | 462 | 2.16 |
| TBitmap.RawImage.Data PaintBox | 482 | 2.07 |
| TBGRABitmap PaintBox | 369 | 2.70 |
| OpenGL | 60.2 | 16.61 |
| OpenGL PBO | 60.1 | 16.63 |
Conclusion the faster method (less duration in ms) with highest fps:
1) Bitmap.RawImage.Data PaintBox
2) TBitmap.RawImage.Data
3) TBGRABitmap PaintBox
