We recently had a new hard drive installed in our machine due to a failure meaning a total reinstall of everything including FS9. I've come up against a problem I had a few years ago that a friend helped me solve when the machine was brand new. Having to reinstall everything again means it's reared its ugly head again.
Prior to the recent PC problem and subsequent new hard drive, the skies, cloud textures and ground colours (after dark) on FS9 looked super. Dusk blue skies merged seamlessly from light colours in the direction of the sunset to dark blues when you looked towards the approaching night. However, at the moment I don't have these nicely blending textures. Instead colours appear as bands in the sky and the cloud textures and ground textures (the latter is really noticeable after dark) look 'oily'. I've attached a couple of screen grabs below.
I seem to remember we did something with the Graphics card set up that fixed it but I'm damned if I can remember what it was. The graphics card is an ATI Radeon HD2400 XT.
I'm not a PC technical expert so please word any responses accordingly!
Any advice or guidance would be gratefully received.
Thanks very much in advance,
Dan
