Part 2: 2D, Acceleration, And Windows: Aren't All Graphics Cards Equal?

By ,

Tom2D: Ellipses

Next up, ellipses. This test turns out much like the rectangle metric.

Ellipse benchmark

Test Content:

A total of 100,000 objects of random size and color, in random positions on-screen, are rendered during this test. We alternate outline color, fill style, and fill color. As before, the random seed remains constant so that all test runs should produce the same graphics. And again, all ellipses are positioned within the confines of the display area to make clipping superfluous.

GDI Functions Called

Drawing ellipses directly to the display:

CreatePenCreateSolidBrushGetStockObjectCircleArcSelectObjectDeleteObject

Drawing ellipses via the DIB buffer:

CreateCompatibleDCCreateDIBSectionBitBlt

Summary

Drawing ellipses doesn't show the same severe performance impact as drawing rectangles. For direct writes, the two ATI cards are trounced by the Intel Atom/GMA 950 combination. And when it comes to buffered drawing, the test field hits a reasonable level of performance throughout.

    I have a 5850 with 10.1 drivers and it seems Photoshop CS4 doesn't recognize it as a graphics card that can improve performance so all those cool new features like animated zoom, kinetic panning, and such seem to be disabled. Also, it when you have a very complex group of objects and you try to nudge it ( move it one pixel with arrow keys) the computer actually shows the spinning wheel and has to process this instead of being instantaneous like it was on my older 7600GT. Is this an issue related with what this article is saying about apps written for GDI or is this a different issue i'm experiencing?

  • It would be great if you can run the test on some "pro" cards (quadroFX, quadroNVS, firePro & fireMV). Just to see if the "pro" drivers change standard UI rendering or the optimizations are only for the professional DCC software.

I have yet to use CS4 on my desktop with my 5850..... I hope Ati comes out with more patches if this is a problem.

    windows XP is dead... get on the windows 7 64bit bandwagon already you Luddites! (not referring to the authors of the article, they raise good points; I am referring to those customers who insist that XP is some sort of holy grail of windows bliss never seen before or after)

    I’ve always preferred GDI operations over those of the NOD. GDI have more basic operations set verses NOD’s more complex and sometimes unreliable operations.
