I mentioned in another thread that my flight sim setup has many (7) 1080 monitors.  Consequently, I’m using multiple networked PCs and WidevieW.  I’ve spent enough time trying to get it all working together smoothly that I finally had to walk away from it all for a bit.  I’m back.

PC= i7-9700K, 32 GB RAM, Z390 AORUS motherboard, RTX-2080.  
 

Should it be possible to put all seven monitors on one PC (by adding a second GPU (RTX-2070) and still achieve reasonable frame rates?  

Thanks.

Depends on what you use them for, I have 5 monitor, but only 1 for main 3D view, while I do use undocked panel/display for other things, normally a popped out FMC on a 7" touchscreen and PFD/ND on another 7" screen. I noticed it have no performance impact on FSL320/CS757/CS767, but on Maddog it have quite some FPS costs when window popped out.

If both used as 3D view, I have seen another triple screen setup, if it's been mixed as 1 wide screen (in Nv control panel) and have 1 view, the performance is smooth, however in such case, the side view feels very distorted, especially in VC.  If use view group manager to make it correct by basically open 3 VC window with different angle, the FPS is hugely hurt, with 1080ti on 3 1080p screen, I can only get around 20 FPS on default P3D aircraft!

Five of the monitors are outside-the-window views arranged in a 180-degree arc.  I like being able to turn my head to look out the different windows to see around, especially for judging when to turn onto base.  One monitor for instrument panel, and one for GPS.  With three monitors for outside views using the View Group Manager, I average maybe 30-100+ fps, depending on the situation within the flight.

I guess I just need to bite the bullet and temporarily cannibalize one PC, take the GPU from one, add it to another, connect up all of the monitors, and see if it works.

thanks again.  Scott

That's the best plan, I think, if it doesn't involve spending money. You don't know what kind of performance you'll get in your particular setup until you try it. Anecdotally, however, I'll say that I've found that any more than two views on a single PC drops the FPS to a point I'm not happy with. I think five may be asking too much of any single PC.

The real problem I suspect you'll have is that only four of your five outside views can be on a single GPU, since no consumer GPU can run 5 monitors directly. Moving a high-demand resource like an outside view onto a second GPU will slow things further down as the multi-GPU scheduling takes up more of the main thread's time. Having just simple 2D panels on a second GPU doesn't tank the FPS in my experience, but it depends on how the gauges are built.
