I currently have the ATI X1800 XT and have no interest in getting any ATI card for the simple reason that ATI cards, all of them, actually have a bug with windows media player 9 or 10 in all windows XPs. The bug has to do with border problems and not showing all 256 shades of gray when the "use overlay" option is checked in the performance options of windows media player.
Im 100% sure about this too, unless an AMD processor would change things. The reason as to how i know im certain is because ive tried the border and grayscale tests on about 4 different radeon cards, ranging from a 9200 to the X1800 XT, as they all failed the test.
The test can actually be easily carried out on analog or digitally connected displays. All you do is create an image in BMP or AVI format that has a white outline on a pure black background so that the outline only covers the edge pixels on the display. What you will see is that the brightness of the outline is not the same on all the sides.
The other test can be done with varying grayscale test images where you will see that step 254 and 255 are the same.
These are not a problem, but they intail the possibility that there could be other image artifacts.
After running my animation, which is a very intricate fractal animation, it doesnt end up looking correct.
Ive tried other media players as they seem to possess the same effect and i also want to stick with windows media player.
And so, by unchecking the 'use overlay' option, the image artifacts are gone as the image looks perfect and the animation looks correct. Only without overlay checked, the playback is much slower and improper in appearance.
After trying the border and grayscale test on a system that had an Nvidia card, i noticed that there was no image artifacts when overlay was used.
So the ATI cards are the only possible causes. Im sure an AMD system could be different, but ive already bought my system and cant change it now. The store i got my system from, even though i didnt get the card from them, is allowing me to exchange my ATI card for an Nvidia card, as they can get the Geforce 7800 GTX 512.
Ironically, its the only component i didnt get from the store and the only one that has given me problems.
So im going with Nvidia, as i dont care for the extra slight performance gains from the X1900 XT, since its negligible compared to the massive performance difference from using or not using overlay, which is about x20 times difference in playback speed. And i cant wait another month either.
I know its crazy that im barking over such a slight bug, but im in a ridiculous situation that i can only describe as one where i am assigned an objective to accomplish and that it has to be accomplished without a single glitch of an error.
So far the BFG is the best Nvidia card out there. Although i think that the store is only going to be able to get me what they can regardless of what i want since these cards are so hard to find. But it still helps to know which one is the best and to make the corresponding request as the first choice.
And yes, it would probably make no difference, but my philosophy is that aim high and you can go to sleep.
