I currently have my XP9 cockpit on a single i7-980x + GTX580 + ATI HD 4800 so that GTX580 drives 3 monitors through matrox th2go for the visual and ATI card takes care of the instrument panel via Simavio. This works great except for the fact that the visual is one 3d view stretched over 3 screens covering about 95 degrees of FOV. The problem of course is that the visual is not very realistic towards the edges of the display when it comes to the sizes of objects and the behavior of the horizon when turning and climbing etc. It would be better to have the 3 screens as 3 different views angled to -32.5,0,32.5 and having 32.5 degrees of FOV on each. Ben’s answer is very informative for me because it means that it is not possible to achieve this with one computer with XP10 either, so now I know that I need to go computer shopping to have 2 more computers to get the kind of visual that I want. The implication of the second answer is not that clear cut, but it seems that perhaps I could do ok by having GTX580s also in the new computers as well.

8-bit color only.

I am not here to go “when do we get the demo?!!” But, based on all the posts you’ve done explaining how x-plane works, I have to say that when the day arrives, I will be tremendously excited. I have a Mac Pro 8 core, with a 5870, and I am uh, interested in seeing how hard I can push it.

(Well, I can do that easily with multithreaded rendering, but i mean.. .you know.. with a little more immediate feedback!)

Thanks for balancing the CPU/GPU behavior of x-plane (this is the part that is on topic.) Its been a little weird to be able to run X-plane 9 at full speed with Blender rendering in the background, while the GPU is barely even aware that something is happening.

As I am about to buy a new 2560×1440 monitor, I have a question about colour depth :

I have a choice of 8 or 10 bit colour (16.7 million or 1.07 billion), so will X-plane 10 support 10 bits and will I notice the difference? I believe my HD 4870 GPU will support 10 bits at this resolution.

In The Bin!….thanks

Hoping that LGA2011 gets some of that addressed next year with quad-channel memory (bringing bandwidth from 25.6 GB/s to 51.2 GB/s) and 40-lane PCIe 3.0 bus (from 5 GT/s to 8 GT/s).

What is being described above (1) is what I’m looking for (building a home cockpit from one single computer), and it might actually be achievable with a couple of existing solutions from ATI (Eyefinity + CrossfireX) or NVIDIA (2D Surround + SLI). I’m planning on doing that myself, learning how it goes during the process.
