Hi there. I found a strange problem in nK PRO 1.3B today (also tried 1.2). While I'd be driving at Donington, random objects around the track (bridges, marker boards and rare cases of the actual track) going transparent or translucent. Sometimes the car itself. I'm not sure if its a problem with the track or its nK PRO but its a very strange issue. I've included a couple images showing the error.

ghosts...

I had the same thing with my 4850, you have to turn off Catalyst AI. No other solution I think.

On my 6870 I no longer have the problem, instead I have new problems!

Thanks Paul. I tried doing that but it hasn't worked . Still translucent objects.

I found out that its the AAMode is the problem. Multi-Sampling AA fixes it or Super-Sample AA but not Adaptive Multi-Sample. Its a shame that it doesn't because it seems to have very similair quality to Super-Sample but is much lighter on the PC's resources so I feel a little bit of controller lag
