Orei,

Check out this link: http://en.wikipedia.org/wiki/ATI_FireGL
There is a table of ati g. cards that can be softmoded, unfortunately 4670 isn't on the list but 4870 is. I would try to install 4870 it might work.

Hi Guys, better late than never, just found an nfo, and installed the |HD 3850 as Fire GL V7700 and SketchUp, ArchiCAD 3d works much better than on original drivers, the photoshop cs4 as well.

got in the same trouble with HD 3850 (512mb), lags - that worries me at most. I'm thinking to go back to my old 5200 FX (128mb) - it had problems with hi-poly structures by was quick. No new drivers helps, unfortunately...
