Good day friends. 

I have spent the last 2,5 years building my full size B738 simulator and have succeeded very well so far. Have been flying around the globe and visited 135 countries so far and no problem. 

I use P3d v4.5, Asus 6gb dual OC GPU (not overclocked to my knowledge), 16gb ram and a few ssd hdd. Pmdg as aircraft, the one and only. Aktive sky in use for real weather and all ORBX softwares worldwide. 

As outside windows I use two TV monitors and one small projectors. Will however go to four TV monitors due to lack of space later. 

Have tested how well the gpu works on a flight today Phnom Penh to Brunei. A two hour flight with no problems as usual. But I wonder how high you can go on graphics settings since the gpu only uses 2,3gb of its memory and has a load between 30 and 55% on a flight like this. Computer memory not more than 7 GB are used on the entire flight. I gave rather high settings and it's running very smooth. But if I increase just a little I get a lagging on the outside TV monitors. Something is wrong but what? 

Obviously I have enough power to run heavy graphics. But what causes the lagging sometimes. That is a major issue. 

When I increase scenery density the lagging begins very fast but I have not been running the gpu and ram test software more than once. 

But does anyone have an idea how to configure graphics settings with my setup? 

I love my build and gave a blog about it but can I post a link to it here? 

Displays are setup to use 1280x1024 for outside view on all three displays and that is no problem for my gpu, even not if I should add a fourth TV to get a 180 degree view. 

Any ideas are welcome and I will try it. 

Hi,

 

Welcome to the forum

 

I think you will find that getting a smooth running system for P3D v4.5, the Options- Display, Options- World and Options- Lighting settings can effect the performance dramatically.

I would suggest you post your P3D v4.5 settings here as well as the sim rig specs.

May be also list exactly what Orbx sceneries, land class etc are installed. Also how many cloud layers are you running in Active Sky?

Good day and thank you for your reply.
 

Active sky cloud layers is set to three.
Lightning settings like this;
Brightness 1.3
Bloom, 0.2
Saturation 1.15

Dynamic reflections OFF
Shadow quality HIGH

Casting shadow obejcts, NONE selected

World settings:
Level of detail radius: High
Tesselation factor: Medium
Mesh resolution: 5m
Texture resolution: 7cm

Scenery complexity: Normal
Autogen scenery draw distance: Medium
Autogen vegetation density: Dense
Autogen building density: Normal

Water details: High
Enable bathymetry: ON

Reflections: Clouds

Special effect details: High
Special effect distance: High

Display options:
Image and texture quality:
FXAA: OFF
Texture filtering: Anisotropic 16x
AA: 4xMSAA
Texture resolution: Ultra 4096x4096

Display settings, all external views from cockpit are set to 1280x1080x32

Frame rate controls:
VSync: OFF
Target framrate: Unlimited (it works best with this at unlimited, if I set to lower value it just starts to hack in the image at once)

Computer specification:
Intel i7-8700 3.7 GHz
16 GB Ram (it uses at most 8050 MB when I look at the memopry monitor)
GPU: ASUS Dual OC 6GB. (uses only 2200 MB of memory in most complex weather) Also the GPU monitor says that it is only using 30-48% of the GPU capacity when flying.

I own every landclass the ORBX has since that does not affect the system much since my system is run on a 64 bit windows 10. That has never been any problems.

I think these specifications are all you asked about. So in my CPU/GPU monitor software (GPU-Z software).

Three main windows are active on my GPU depicting left view, front left view and right view. Do currently not have a display for the fron right veiw but will soon add two larger displays for front view. But I will keep the resolution set to 1280x1024 since this is good enough I guess.

Any advise to get more dense scenery and more "real" visual on the flight siumlator is appreciated.

Thx for the info. A couple of things I would try settings wise would be...

 

Lower your texture resolution to 2048x2048 based on the monitors you are using.

Also I didnt see it in your list but Shadow Draw Distance may be best set to Medium.

Also its been reported that the Dynamic 3D Autogen option can create issues so try disabling this if not already turned off.

 

 

If this provides better smoothness in your sim, you can then experiment with increasing the LOD and Tessellation Factor to increase the detail of the scenery.

I would start there at least. There are other optimizations you can do after that.

 

Comment: I didnt see any info on your observed CPU load when flying. The important thing with P3D is to achieve the right balance between GPU and CPU so neither one is topping out.

You quote the i7-8700 at 3.7GHZ. I would be aiming to clock at least above 4Ghz.. If this is the locked version of the 8700 (the non K version) , there are ways and means to get it to 4-3-4.4GHz.

 

Hope that helps...

Thank you for your reply. Will take a look into the items you suggest.
However I am not familiar in how to change the processor speed etc. I have been monitoring it sometime and seen that it goes up over the specified value, once I have seen 4,1 GHz but I cannot remember how or where I did see that.
The GPU-z does not show any data of the CPU other than temperature, is there another tool I can use to monitor processor during flight?

CPU-Z

CPU-Z

Thank you

Have been trying the CPU-z which only give momentarily values, and cannot be run constantly like GPU-z.
But still the CPU-z shows that the frequency my processor is running between is up to 4,5 GHz so I guess that means it is unlocked.

Hi. Thank you for the instructions. Have limited the texture resolution to 2048x2048, no problems and scenery looks the same as with 4096x4096.

Shadow draw distance in disabled on my setup. I do not mind shadows missing, that is not important to me.

Dynamic 3D auto gen is disabled since ever in my setup.

Tesseleation factor is set to medium and have tried different settings, and it does nothing to the sim smoothness on my system.
You can all see my setup at https://boeingflightsim.wordpress.com

The GPU load is never higher than 57%
CPU I do not know, the CPU-z is impossible to run on top of the simulator. GPU-z is easy to set always to be on top but there is no such function in CPU-z what I have found so far.

Thank you all for your help and support with my problems.
