Why is my 3D accelerator not supported by WoW?

There could be several reasons why World of Warcraft (WoW) does not support your 3D accelerator:

• Incompatibility – Your 3D accelerator may not be compatible with WoW. WoW requires a certain level of graphics capability to run smoothly, and if your 3D accelerator doesn’t meet these requirements, it may not be able to handle the game’s graphics.
• Outdated drivers – If your 3D accelerator has outdated drivers, it may need to be able to support WoW. Updating your drivers can help resolve this issue.
• Insufficient system resources – If your computer needs more RAM or processing power, your 3D accelerator may be unable to support WoW. Upgrading your computer’s hardware can help improve performance.
• Unsupported hardware – WoW may not support your 3D accelerator because it is an older or less common model. In this case, you should upgrade your hardware to a more widely supported 3D accelerator.
