Gripfire

Hi there people, I bought this game when it first came out YEARS AGO... to me then it was way too complicated for my small attention span. After visting my old junk drawer in my mums house interstate I found it again. Now im really getting into this game. It still has so many great things that i didnt appreciate back then. It runs fine on my 'newer' machine however im experiencing some flickering on the leading edged and highlighted areas of the aircraft also the smoke and graphical effects turn blue/grey/green ?! (explosions, smoke ect). My graphics card is a Geforce 8000GTS, 2 Gig Ram DDR2, XP Pro 2002. I've donje some tweaking in the Nvidia control panel which fixed up some other issues but these probs still havent been ironed out yet. Any tips? (I should also see if there are any patch updates for my card!) Thanks in advance
