May 5, 20197 yr 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: How do I synchronise the vertical frame updates across both cards? Do I need an SLI connection between the two cards to achieve item (1)? Does Prepar3D make any use of Nvidia's RTX technology? Has anybody driven 5 monitors / projectors from Prepar3D? Any recommendations for a suitable cards to buy would be welcome. Richard
May 24, 20197 yr This will not work as with each extra view you will loose 40% fps.. You need at least 2 view pc,s.. 5950x3d 5.4-5.7 GHz - Asus ROG 870 Crosshair Apex - GSkill Neo 2x 24 Gb 6000 mhz / cas 26 - MSI RTX 5090 Gaming Trio OC - 1x SSD M2 6000 2TB - 1x SSD M2 2800/1800 1Tb - Corsair 5400 case - Corsair 360 liquid cooling set - 3x 75’ TCL tv. 13600 6 cores @ 5.1 GHz / 8 cores @ 4.0 GHz (hypterthreading on) - Asus ROG Strix Gaming D - GSkill Trident 4x Gb 3200 MHz cas 15 - Asus TUF RTX 4080 16 Gb - 1x SSD M2 2800/1800 2TB - 2x Sata 600 SSD 500 Mb - Corsair D4000 Airflow case - NXT Krajen Z63 AIO liquide cooling - FOV : 200 degrees My flightsim vids : https://www.youtube.com/user/fswidesim/videos?shelf_id=0&sort=dd&view=0
May 28, 20197 yr Author 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.
May 30, 20197 yr Author 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.
May 30, 20197 yr Author 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: How do I synchronise the vertical frame updates across both cards? - Doesn't seem to matter or the cards are synched together somehow 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. Does Prepar3D make any use of Nvidia's RTX technology? - Not currently - this seems to be general knowledge. Has anybody driven 5 monitors / projectors from Prepar3D? - Yes me 🙂 Any recommendations for a suitable cards to buy would be welcome. - EVGA RTX 2080 Ti Black Editions seem to work fine.
