What about DX10 wing lights?

Hi,I did a quick search on the forum and found that there seems to be some problems with the DX10 preview in SP2, but I couldn't find any specific solution for my problem:I have very bad winglights in the default C172. The navigation lights look bad and the wing strobe lights are missing. In DX9 mode the lights look allright. Is this a problem with the Acc/SP2 or the nVIDIA drivers (169.04 beta)? Anybody have any solution for this?Ulf B :-)Core2Duo X6800 OC 3.3GHz, 4GB RAM8800GTX, dual view 1920x1200 and 1280x1024Creative SB X-Fi (Gamer mode)Vista 32, FSX Acc/SP2WinXP Pro SP2, FSX SP1, FS9.1
