Thank you, thank you, thank you.
I have had the game for ages now but as my primary machine is a laptop with a GeForce 460 Go I was resigned to the fact that I would not be able to play the game until I could afford to upgrade the machine.
Then I read this thread about how nVidia faked vertex and pixel shaders in the driver and this was removed at some point in the past.
Now I have been religiously updating my drivers when a new one came out. So I uninstalled the latest driver and put the one that came with the system back on and UC runs YEAH!!!!!!!!!!!!!! It may not look its best but at least I can now play the game.
Time to take my Megaron for a spin ¦¬) Oh happy day.
