Graphical Artifacts in SC2 on Mac

  • Graphical Artifacts in SC2 on Mac Matt

    Has anyone ever encountered trails/artifacts as in the picture while playing SC2?

    enter image description here

    I've tried other 3D apps on the machine such as Portal2 -- That worked just fine. Wondering if anyone has encountered this before and if so how it was resolved.

  • Typically artifacting of this nature occurs when a GPU is either damaged or not cooled properly. If the GPU is still artifacting after providing substantial cooling improvements then it is probably irreparably damaged.

    Heres what you can do:

    1. If your laptop actually has vents on it blow it out with compressed air. Dust in a heat sink will always reduce it's ability to dissipate heat.

    2. Get a laptop cooling stand/dock. Typically you can spend $30-$70 and see great improvements simply from helping your laptop cool better.

    3. If you are technically inclined, or know someone who is, you can replace the thermal compound on the GPU. This is not something you should do if you do not know how to do it, as things can very easily go wrong.

    4. Have you contacted Apple? (You probably should)
