But where does reside this limitation ? How is it possible that a gfx card has a minimum pixel/seconds limitation ? The arcadeVGA is able to do very low pclock : http://www.ultimarc.com/avgainf.html This gfx card has been designed for the purpose I have. But I wonder to know what is different from other cards? Is the pclock limitation written in the bios ? Is there a way to force X to use lower pclock than 12.0 even if it says that the gfx card range is 12.0 - 350 Mhz ? _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
