I've been flying the Fenix for more than 90 minutes and I can notice there is a some kind of memory leak. I was at 55fps when I started my flight and now I am at 40-43fps.By the time I will be landing I will be in the 30s.

I suggest you don't go back down that path of tweaking every little thing like in P3D. It's just not really worth the time and effort on MSFS. It works without it.

That's very true. These "tweaks" are not really necessary.

I guess in some ways I don't mind the tweaking as I want to get as much performance out of my rig as possible. In fact, I don't think I'll ever stop tweaking as long as I am a simmer.

I really wish they can introduce a DYNAMIC LOD system so that we don't have to constantly fuss with this setting.

Absolutely.

Just went to KJFK for some stress testing of the Fenix. I threw in AIG set at 79% and even though I reduced terrain LOD to 150 I could not get more than around 25fps.

I flew in and out of JFK yesterday ( No AIG, just simple traffic) and it stayed locked to 30 FPS.

AIG can certainly make a significant influence. I'll probably need to reduce settings further to be able to reach a stable FPS in places like JFK and LHR. 

EDIT: At KORD I get 27fps with AIG set to 79%. With AIG off I get 38fps.

I installed some AIG but my old system cant handle traffic. What impact is there if you are not using the AIG traffic controller? Is it then the % for AI offline that counts? I saw alot of european airliners in Vegas today. Guess its not working like the P3D?

Thanks Michael Moe

You may want to consider the NDU tweak. 

Quote

NDU stands for Network Diagnostic Usage. It basically monitors the network data usage.

Why is it related to MSFS?
Because in MSFS Data settings, you can see that there’s a Data Consumption and Limitation feature. Somehow MSFS is using and connected to Windows’ NDU to monitor the data consumption. As you already know that MSFS is constantly downloading data from the cloud during flights.

Why disabling NDU may make MSFS smoother and more fluid?
Because most probably there’s a bug on Windows’ NDU (e.g. memory leak or process leak) which affects MSFS performance.

Thanks got it

here‘s the build I found but could not download and test yet myself, I saw one user reporting 10pm more though. Nonetheless use at your own risk or wait for an official update

Did anyone actually get to use the experimental version with positive results?

You have a better system than me. I do 4k at 100% render scaling with Ultra on everything and 200 LOD. AIG at 50%. There were storms in KJFK yesterday and I was able to hold 33FPS without locking and 30FPS locked.

So I definitely think it's AIG for you.

CPU does matter. 5800X3D to the rescue. Perfect 60fps on Vsync while waiting at the gate

Awesome to hear!  I ordered one from AMD Direct this past Wed and it arrived yesterday.  I should have time to install it tomorrow.

If anyone can compare the 5800x3d with the 12700k specifically with the Fenix I would be grateful. I wonder if the massive lead the 5800x3d has in MSFS is still there once the Intel cpu uses the igp for the Fenix.

Just started using RTSS (again) for FPS lock. Highly recommended. It also gives a nice overlay with various variables like CPU, GPU, RAM usage and temps (and much more, it’s highly customizable). 

I don’t personally see that much difference between FPS locked to 30 or 40 though. And by the way the most “hard-working” core is the same whether I’ve got FPS locked or free. Making sure the Fenix apps are not using the most hard working core does make a lot of sense. It does take some fiddling with core affinity though. 

In terms of AI traffic, that’s another thing that will put a load on the CPU, as @Fiorentoni mentioned. Running Asobo Live traffic that’s an either on or off situation. But with offline traffic there’s a slider. So this could also be something to consider if you’re CPU bound. There’s also other traffic settings like ground traffic and ships that could have an impact.

Do you know how to turn VSYNC on in RTSS?

I am using RTSS to monitor performance of the Fenix with the on screen displays you mentioned. Currently I have VSYNC turned on and an FPS lock in NVCP (Not saying how much through fear of poking the bees nest !! LOL) I would like to try the same thing with RTSS, I can see how to set the FPS but wasn't sure how to turn VSYNC on.

Make sure you have entered a number in "Framerate limit" in RTSS. Go to "Setup" and make sure "Enable framerate limiter" is ticked. For V-sync I'm using the "Vertical sync: fast" option in Nvidia control panel. "Max Frame Rate" is also off in NCP. Of course V-sync in MSFS is turned off. An advantage with RTSS as mentioned is that turning framerate limiter on or off has an instant effect in the sim, as opposed to NCP settings.  

By the way, you have to use MSI Afterburner to select which items are displayed on the overlay. For some values, like FPS, it's also possible to show a graph. This is quite useful for framerate, as it gives an overview of how much fps changes over time. To enable both text and graph, change this in the box that I've circled in the image below.

I didn't realize you were still using NVCP to set your VSYNC, I have never tried the "Fast" option I have it set too "On" I wasn't sure if you could use RTSS to also turn on VSYNC

I will give these try.

Appreciate the help

Well I'm sure VSYNC ON in NVCP is ok. I'm using the fast option as that works best for me. Apparently Nvidia handles VSYNC better than MSFS. RTSS is for framerate limiter, not VSYNC. 

Just experiment a bit and find what works best for you 🙂
