Updating mac video card

Rated 3.88/5 based on 933 customer reviews

(The new Mac Pro released in 2013 is partly upgradable but you can't install a new graphics card.) It's easy to get excited at this stage because post-Power PC Mac Pros have their graphics cards in an easily accessible PCI-e slot.And the PCI-e form factor is popular in PC motherboard manufacture. Again, fairly widely supported in the world of PCs.Now let's talk briefly about what can't be upgraded or hacked.Put simply, it's often not possible to upgrade the CPU in a Mac, or its GPU (that is, the graphics card).For more information about how to find out what graphics card you have in your PC, click here.Once you know the kind of graphics card you have, visit the manufacturer's website to download the latest driver.There are exceptions, but even then it's not trivial or recommended for most users.

Updating drivers can often correct odd visual behaviors such as freezing, artifacts, model slicing, and slow performance.

Here are links for downloading drivers from the most common graphics card manufacturers: If you upgraded your driver to resolve a display issue, and it didn't resolve the issue, you may consider installing an older driver for your graphics card instead.

Older drivers may be available online or in a resource CD that came with your computer.

The latter seems more plausible to me, but either is just speculation.

The end result, though, is that there are rarely issues with Apple graphics drivers & regular software or games; again speculation, but for games I imagine they write to a pre-defined rule-set, rather than try to constantly be pushing the boundaries.
