Graphics card recommendations for driving 5 projectors

[RichardMaskell 0]

I am in the process of building a simulator for training glider pilots. It consists of the front half of glider fuselage mounted on a stand, surrounded by five 2.5m wide projector screens giving a FOV of 235 degrees. The projectors are low res, running at 1024 by 768 - we need the 4/3 aspect ratio. We just got the system running using a development PC with a single graphics card driving 3 of the projectors. 

Assuming I need 2 graphics cards to drive 5 projectors I would appreciate advice on the following points:

1. How do I synchronise the vertical frame updates across both cards?
2. Do I need an SLI connection between the two cards to achieve item (1)?
3. Does Prepar3D make any use of Nvidia's RTX technology? 
4. Has anybody driven 5 monitors / projectors from Prepar3D?
5. Any recommendations for a suitable cards to buy would be welcome.

This will not work as with each extra view you will loose 40% fps..

You need at least 2 view pc,s..

I hope you're wrong, I have bought a PC and am in the process of configuring it. I should try it later this week. I'll post how I get on.

I got it running last night with the 5 projectors all running at 1024 by 768 and an extra full hd monitor. With the scenery options all roughly midway or higher and all the anti aliasing maxed out it was managing over 40fps on a single PC. Rather relieved to be honest.

For completeness I can answer my own questions:

Assuming I need 2 graphics cards to drive 5 projectors I would appreciate advice on the following points:

1. How do I synchronise the vertical frame updates across both cards? - Doesn't seem to matter or the cards are synched together somehow
2. Do I need an SLI connection between the two cards to achieve item (1)? - No, SLI must be disabled to drive the video outputs on the second card.
3. Does Prepar3D make any use of Nvidia's RTX technology? - Not currently - this seems to be general knowledge.
4. Has anybody driven 5 monitors / projectors from Prepar3D? - Yes me 🙂
5. Any recommendations for a suitable cards to buy would be welcome.  - EVGA RTX 2080 Ti Black Editions seem to work fine.
