I have a background made up of several 512x512 tiles and the layer they are on scroll horizontally only and have enabled the point sampling for that layer. I�ve run a few tests on machines running a mix of GPU�s such as nvidia 6155 mainboard combo, a gforce 8800gt card, and an ati firegl 7600 to check performance.
The only GPU I�m having problems with is the ATI firegl 7600 card. I know it�s not a consumer card that the typical gamer will want to use, but to satisfy my curiosity I was wondering if anyone else has similar issues with seams randomly showing every now and then with this category of card. These seams flicker for a split second and go away then later they may flicker, it�s consistent every time no matter how fast or slow the layer scrolls. I�ve tried different ATI drivers, enabled �reduce DVI frequency on high resolution displays� and enabled �Alternate DVI operational mode� but these seams always show whereas the other GPU's run perfectly fine seam free.
