I Have an iMac 27" with NVIDIA GeForce GTX 780M 4096 MB and I stretch the screen across three monitors with HDR settings and so far so good. I can't wait to try this beauty out. From the older videos to the newest ones on this plane, even though you say it's not quite finished yet, I think you are way out in front of everyone else. I have about 50 or so payware aircraft, and from what I've seen in Jan's videos and the pictures that you guys have posted, I'm a huge fan. Thanks for all your hard work, and you will all reap the rewards of your hard labors as soon as this plane is released.
