Just thought I would drop a quick note to say I have solved the white flashing images in the JS4100 VC cockpit. that some users have reported, in my setup anyway.I have been using NHANCER with the 182 NVIDIA drivers as this gave me the best image within Flight Sim as well as good performance. Later drivers caused me various problems.With the announcement of NVIDIA Inspector being available I changed to the latest NVIDIA Drivers and set up Inspector as advised by Nick Needham.I now have ice effects and VC rain in the JS4100 and no artifacts/flashing white images. I also have the benefit of NVIDIAs latest drivers.I use Win 7 64 bit, FSX and 260GTX graphics card.Hope this helps someone; thanks to Nick Needham.My regardsDavid MillerUK
