Some of the avivo controls dont work with my Gigabyte HD 4870 with the 8.8 drivers. Dynamic contrast will not enable. Its not greyed out but when I enable it and pres ok its disables as soon as I go back into the ATI Control centre. When I set edge enhancement and de-noise then press ok (Apply is greyed out when I do the settings) theyre back to default as soon as I go back to Control Centre.
