    You can edit it manually or you can run a reg tweak as shown below:

    Catalyst 10.12 - sites.amd.com - download

    --> To enable Morphological Antialiasing for ATI 5000 series, use the reg tweak:

    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000]
    "MLF_NA"="0"
    "SurfaceFormatReplacements_NA"="0"
    "TFQ_NA"="0"
    
    Save it as MLAA.reg, click to run and apply. Don't forget to reboot for the changes to take effect.

    --> MLAA.reg - tested on Catalyst 10.12, 10.11, 10.10. Will most likely work on future versions as well.

    I too use Fraps, and also Windows scissors, HyperSnap, and Winsnap.


    For the MLAA, do as follows:

    1. Check if your card is ATI 5000, it has to be to support MLAA
    2. Control Panel -> Programs and components -> Uninstall ALL ATI software
    3. Reboot into safe mode to clear ATI registry remnants with the Driver Sweeper from Guru3D:

    Guru3D - Driver Sweeper

    4. Download and install Catalyst 10.12, clicking on the pop-up to confirm to "Install [this unsigned] driver anyway"
    5. Reboot
    6. Run MLAA.reg and confirm to apply the registry changes:

    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000]
    "MLF_NA"="0"
    "SurfaceFormatReplacements_NA"="0"
    "TFQ_NA"="0"

    7. Make sure to reboot for the registry changes to take effect.

    Enjoy.
