Ze-Jamz: yup, that’s what I have found. It’s most noticeable over London where switching it between ‘unlimited’ and ‘high’ in game (doesn’t require a restart) alternatively textures all the buildings (22fps) and not (35fps). Everywhere else the buildings are textured as they appear due to the lower amount rendered (I don’t why they couldn’t have made the default colour grey instead of brown, as this would have made them a lot less obvious!)

AndyJWest: I only run 50 Hz because it’s available with my monitor (Samsung 21.5” LED), and theoretically provides a performance gain (haven’t actually measured the difference). I have made no alterations to configuration files or CCC settings, and both cpu and gfx card are at default speed. My lowest frame rate over London is around 30 fps, dropping to about 28 when flying through Tower Bridge, I don’t know why yours would be lower – maybe the refresh rate is making more of a difference than I realised. The only ‘tweak’ I’ve made is to install the latest CAP (Catalyst Application Profile) version, although again I don’t know if this has made any difference. If you want the latest version, have a look at Guru3D.com as it wasn’t on AMD’s site the last time I looked.
