Fenix and performance

I also had this problem once, but I couldn't ctrl alt delete out of the sim, because microsoft.exe wasn't even showing up in the task mgr for me. So I had no option but to restart my computer. After this, everything worked. I believe there was some problem with MSFS trying to communicate with the external Fenix app trying to get it to properly shutdown but somehow got stuck in the process. I really hope the devs can find a better alternative then having to load this external app. Seems like its doing more harm than good,

its happened to me a few times and I just have to ctrl alt delete then can see and close the .exe - interesting what you say about the fenix app because I think some people have been closing it completely to improve performance once I flight has started.....

Don’t think that’s going to happen friend (getting rid of external app). That App IS the airplane

many people are suggesting this to improve performance (but only once your on the runway!) - have tried and it does work but it didnt really improve my performance.................

Before you all point fingures at the app.

Look at  CPU cores your MSFS is using and if you have not set a FPS cap lower than the FPS you can see/get, your more than likely CPU bound.

Now take all of fenix running apps off the CPU cores MSFS likes to use.

The Fenix displays on my PC dont not use CPU core 0-9 it use 10-19, Totaly wrong for my PC as MSFS use core 19 the most, so I take Fenix Displays off 10-19 and make it use 3-9. As 0 and 1 is also not good.

Tip if you load MSFS the Fenix bootstrap app will be there if you change the cores that users it will do all the same for all Fenix apps apart from the fenix diplays app.

So the point is, if your CPU bound and cannot run your MSFS at 85-90% load on the cores MSFS likes, then your asking for trouble running any other apps of any kind on MSFS cores, becasue when msfs core are at 100%, good luck with stutter etc.

I can't imagine using a 77 inch screen as a PC monitor, unless is was many feet away from me. https://www.avu.ca/video/perfecting-proximity-finding-optimal-tv-viewing-distance/

I wasn’t planning on using it as a monitor initially. But after using it for quite a while it’s very hard to return to a traditional desktop setup.

No, if the app isn't working, the plane will not work. The app, as stated above, is the actual airplane. All the system logic is running in the app. You may not see the app running, but check your task manager and you'll see three Fenix apps running as background processes. If you kill them, your plane will stop working. It will simply fall out of the sky and none of the avionics, buttons dials, or displays will work. 

 

Try killing the Fenix processes and see what happens to your plane while it's in flight..

The reason flight simulator "doesn't like overclocks" is because it gives the cpu a workout, and runs for an extended time

The overclock was probably marginal to begin with and I don’t think I put it through enough rigorous testing. I guess I was just lucky before the Fenix arrived and pushed the CPU over the edge. I managed to solve it though.

How do you control which cores the Fenix will use? Thanks

thanks for the reply - but please can you explain for the non technical! - assume your suggesting keeping the app running but remap the cores MSFS/fenix is using? (also not sure how to tell if i am CPU bound but would assume yes as am running a i7 with a 2080ti)......

ok got it - so eventhough the app is not opening its running in the background......................so really just keep the app open as it will make no difference to performance then.....

Yes, the launcher you see isn't going to hurt your performance. Fenix runs outside of the Sim (which is why it cannot come to Xbox). All your control inputs are sent to the background app, which then sends display updates to the plane and it does what it's told. In effect, the plane is using MSFS just as a display engine, all the plane logic and behavior is managed by the external process.

What do you use to monitor and assign cores differently?

[Pochi 68]

There is an experimental version of the app available through their Discord. It can be tested right now with 2 more option regarding multithreading that should give a performance boost. 

An update will come soon I guess. Maybe we should just wait a bit.

To watch your CPU 

CTRL-ALT-DEL

TaskManager

Performance

Open Resource Monitor

CPU.....expand to see all at the same time.

You should now see all your"cores" and the load on them. You will see MSFS hammers a core.

Now go back to the Task Manager window

Details

You will see a list of apps on the left. Fine the ones you want and

Right click

Set affinity

Now you will see a list of cores that app is using.

---------------------------------

Now load up MSFS turn off any FPS cap if you have one and watch for the core MSFS hammer, thats the core to make sure is not at 100%, Now Lock your FPS, lower you FPS and your LOD if need be till you see it at around 85%. 

Now go from there.

You omitted the part of his quote that he is talking about a 77" TV. If you can't tell the difference between 1080 and 4k on a 77" display then you probably need some Hubble Telescope level corrective lenses. 

And a new tongue if he can’t tell the difference between those wines.
