    Hello, I decided to run Unigine's Heaven benchmark and with AA enabled (2x, 4x, or even 8x), the picture becomes garbled and distorted. This has happened on 2 flashed 5870s and so I was wondering, is this a problem with the application itself or a problem with my cards? Has anyone with a 5870 run the test with no problems on their computer? Thanks.

    You should probably mention what OS you are in.

    I have found that Valley won't run properly on anything less than 1 Gb of VRAM. You might be on ragged edge.

    Hey Macvidcards, I'm running 10.7.5.

    The card is the 1GB model so I'm definitely on the edge. It's just weird that as soon as AA is enabled, all I get are green boxes and red dots (not moving so they don't look like artifacts) on the screen.

    Whelp, I should have thought more about how I could go about solving the issue. I went ahead and put the card into my PC and ran the test at 8x AA with no problems.

    Works fine with the HD 5870 (Apple sold card), and an MVC HD 7970. OS X is version 10.10.2

    Update: Upgraded my OS to Yosemite and the program ran fine. Must be an issue with the drivers with Lion.
