Hello All,

I have been testing my Sim in various operating modes with the new Optoma ZH406ST Laser projectors.  I finally settled on some settings that allow inputting 4K (3840 x 2160 each of three projector)resolution, for a 11,520 x 2160 total resolution for the NVIDIA Surround Display that is processed by Pixelwix for use with P3D v4.5.

The 4k display data is downscaled by each projector to HD quality, resulting in a really nice HD 210 degree wrap-around display.  However, this is a lot of graphics data for my single i7 Sim computer to process -- even with the new  NVIDIA RTX-3090 GPU installed.

As a result, I am seeing an occasional and random disengagement of one of the projected displays, which results in an image shift of about 1" on the projection screen.  This "glitch" typically occurs during a turn on the ground or in flight.  It does quickly correct itself, and comes back into proper warp/blend alignment.  If you are not looking for this glitch, it is easy to miss.

However, this behavior was a little disappointing.  Having tested this setup in different configuration modes, I now have it where this display glitch is minimized, but not good enough...    What's the solution?  Spend more money... :)

I have wanted to upgrade my Sim Computer, so this was the excuse I needed.  My single i7 Sim Computer has been a limiting part of the Sim system, considering everything I am running -- hence the computer upgrade.

Here are the specs of the new Sim Computer for those interested:

- Intel Core i9-11900KF 5.3GHz 8-Core CPU
- CPU with Turbo Boost Max
- 32 GB DDR4 4600 MHz RAM
- 2TB WD SN850 NVMe SSD (very fast read/write)
- 1 TB EVO 960 SSD
- 4 TB Seagate IronWolf HD (for VEEAM Backups)
- GigaByte Z590 Vision D Motherboard with WiFi 6
- EK 360 Liquid CPU Cooler
- 1000 Watt Power Supply
- Windows 10 Pro Operating System

This CPU will allow me to run at 5.3 GHz single core under Temp control, with some cooling assist from the IP Cooler I have near the Sim, located in front of the 6dof Motion Platform.  Benchmarks on this CPU setup show that I should see about a 40% speed improvement over my current Sim computer.  In addition, the RTX-3090 was designed to preform best with the newer processors/motherborads, so there may be some improvements there as well.

I should have this new computer installed in the Sim in a couple of weeks.  Hopefully I will be able to report some good news on the actual performance of this new Sim computer setup.


Full-scale 737-800 Sim; P3d v4.5x with Sim-Avionics (two computers), FDS MIP,  FlightIllusion hardware.  3-Optoma ZH406ST Laser HD projectors, with 4K inputs from a single Nvidia RTX-3090 GPU, resulting in a 210 deg wrap-around display.  6dof Motion Platform using BFF 6dof motion software, driven by a Thanos Servo Controller to 6.2 KW Servos, Lever type actuators.



You are in the search for the Holy Grail!

But I wish you luck and sincerely hope it makes a step-function difference.  I'll be the first one to duplicate it all if it does!

Awesome new system Mike, and looking forward to you letting us know how things turn out.

My favorite thought, you gotta "Love the White Rabbit"! ;D
