I have just bought an HP Media Center computer (m1160n), and upgraded the graphics card to a 256Mb Geforce. 3D Mark 2003 reports that my AGP aperture size is just 4Mb, and this may explain the fact that I get some stuttering in some applications/games. However, in the advanced bios there is no setting to change the AGP aperture size. The system contains an Asus motherboard (a new type called "Salmon", which is apparently made specifically for Media Centers), running the Award Bios. The bios version is dated 26th September 2004, and there are no updates available on the Asus site. Is there any way I can change the aperture size - it is surely a bottleneck in my system at the moment. It seems strange that there is no option in the bios to change it!
Thanks for any help you can give.
