VIA CPU to AGP2.0-AGP3.0 Controller is a graphics video adapter produced by VIA technologies. Video cards are also known as graphics card or a graphics accelerator card. It is an expansion card whose purpose is to generate as well as output images to be displayed. There are video cards which have additional functions such as a TV tuner adapter, FireWire, TV output, light pen, MPEG-2 as well as MPEG-4 decoding. Other than being used on IBM computers, video cards are also used in devices like Commodore Amiga, Atari Mega ST/TT and MSX among others. When the mainboard has a video card intergrated in it though this happened mostly in early computers. When it happens, the card can be referred to as a video controller as well as a graphics controller. The VIA CPU to AGP2.0-AGP3.0 Controller therefore connects to the motherboard through AGP.
Unless you update your drivers regularly you may face hardware performance issues.
To check your drivers you should manually verify every device on your system for driver updates
With the development of computers into more and more sophisticated devices, the se of the PCI interface have diminished and the AGP is increasingly being taken up. The advantage that AGP has over PCI is that it gives a dedicated pathway from the slot to the processor instead of having to share PCI bus. This point-to-point connection has enabled AGP to clock a faster speed than PCI. Sideband addressing is used in AG. It means that the address buses are separated from the data buses therefore no reading will be required in order to get the addressing information. The additional 8- bit bus enables the graphics controller to give new requests as well as commands simultaneously while other data for AGP flows through the main 32 address lines. Thus compared to PCI cards, the VIA CPU to AGP2.0-AGP3.0 Controller has increased data throughput. It is highly recommended you run a free registry scan for and VIA CPU to AGP2.0-AGP3.0 Controller errors before installing any driver updates.
