Not sure if what I am seeing is because I've updated the addon manager that came out after the P3Dv2.3 patch or not so I'm asking. Basically I am waiting on the FSUIPC to get its v2.3 update before I update P3D from v2.2 to 2.3 so I am running P3dv2.2 with the FSDT Addon Manager for v2.3 and I am getting all kinds of shadow flickering at KIAH and KDEN. The only airports I have tried. I know KDEN is not FSDT but does use the addon manager. Anyway my question is this something that is due to not having v2.3 or do I have another issue?
