Slower Ladybug off-screen rendering performance with ATI graphics cards.
Last Revision Date: 5/26/2014
In some cases, customers using ATI graphics cards to perform off-screen rendering of images from Ladybug series cameras should expect slower performance. In particular, performance is diminished when image width in pixels is not a multiple of 8 or 64.
The following table of example results was produced with an Asus ATI EAH3450 graphics card. Performance times are measured by invoking Ladybug API functionladybugRenderOffScreenImage(). In this case, performance is diminished when image width is not a multiple of 64.
Resolution | Performance |
---|---|
1919x1024 | 806 ms |
1920x1024 | 136 ms |
1921x 1024 | 805 ms |
2047x1024 | 855 ms |
2048x1024 | 143 ms |
2049 x 1024 | 859 ms |
Similar results were observed with other ATI cards, including ATI Radeon X1650 and ATI Radeon HD 2600 Pro.
