Hey everyone, 

I just received my RTX 3070 Gpu, and what an improvement in comparaison to my gtx 1080, 

So I did a few test flight with the Cessna 152, I put everything in ultra, all sliders to the right except render scaling, I leave hate one a 100 as I am on 3 1080p monitors, 

Over small airport and city I have a solid 35/40fps at sunset with a lot of clouds, 

Did a try over Miami and here I dropped to 17FPS at the airport and 23fps over the city, 

When I have a look a the devs console it says "limited by main thread" which I guess mean my CPU or at least a core of this one 

Would that mean I should take my wallet again and buy the new cpu I was looking for ( ryzen 9 3900x) or that would change nothing as it is a matter of game code optimisation ? 

 

Thank you for help 🙂

I am not certain on this, but i heard on the MSFS forum that there's supposedly another tweak to the CPU issues in the next update. Maybe best to wait and see.

That's what I heard too but I was not sure 😄 

What CPU are you currently running and at what frequency? Have you tried enabling hyperthreading?

You can turn on developer mode and see if you cpu is bottlenecking the fps. That will help you to decide if change the cpu will improve performance.

Asobo said they are looking for an improvement of around 10% on the 'limited by main thread' issue, so although it is always good to get some improvement (and it may help people just on the edge of 30 FPS) I would not expect the optimisation to be really earth shattering; they are just looking to unload the main thread as much as they can.

There has been much debate but not much experimentation or evidence on the CPU side of things.  6 core or 8 core?  Is outright MHz still a factor?

I would say, definitely 6 core or more processor, and yes, MHz is still a factor, otherwise we wouldn't be getting 'limited by main thread' messages.  

I have a 6 core (12 core with hyper-threading) Intel I7 running at 5.1 Ghz, with a GTX1080Ti  running at 4k 80% on mainly high in sim settings, and mine says it is mainly limited by GPU, so in my case, I need an RTX 3080 for Christmas.   (well, that is what I have told the wife!)  😁 

PS.  Yes, definitely hyper-threading ON.  👍

You should probably hold off but if you do upgrade you should look at the new 5000 series instead the 5800x is looking very promising.

thank you all for answer, I'll wait for the update and decide at this point 

 

Currently have a ryzen 7 1700X 🙂

It sounds like you are not exploiting a major strategy to get the most out of your hardware, and to accomplish this 'free' method you have a couple of ways:  1, use vsync to a 30Hz capable display if you have one or if you don't.... 2, use MSI Afterburner w/ RTSS to limit frames using its scanline x/2 option, which simply means your typical 60Hz screen becomes the x, and dividing by 2 limits frames to 30/second.   If you're not doing one or the other, and I believe #1 to be the best option if you can do it, then your CPU is busy rendering frames that really don't improve your experience enough to pay the overhead for it, that is to say a smooth stutter-free 30 frames is good enough and anything over that your CPU has to help produce.   BTW, w/ the vsync to 30Hz method you have to set the frame limit to 60 in sim, but this yields an actual 30fps.

Hi

 

I have 3 simple 1080p monitor which I guess is 60Hz ? 

 

So you think I should download msi afterburner ? even If I don't have any msi hardware ?

MSI Afterburner works regardless of brand of Nvidia Hardware, and i use its auto OC functionality to get an extra boost and that boost is going to be dependent on a bunch of variables built into your card. In your case you need to wait for two things

1. The optimization promised by Asobo in the next update or two.

2. The new reviews that are being dropped TODAY comparing AMD's new Zen 3 5000 series processors vs AMD's current offerings and Intel's current offerings. (Try and find reviews that include the sim in its benchmarks at the resolution you fly in). I personally go with Gamers Nexus but that may get very technical)

You will also note the motherboard and cpu combination that you are currently using as the motherboard generation will decide if and when you will be able to upgrade to the new 5000 CPU if you decide to do so due to the release schedule of BIOS updates depending on the motherboard architecture.

 

Also be very aware that this is new hardware release season and is absolutely the worst time to buy high end parts right now. I strongly recommend doing the research now (Which also gives Asobo time to do their optimizations) then buying with higher availability early next year.

If you have a 400-series motherboard or up, it's likely you could flash the BIOS and put a 5000 series chip in there. But the updated BIOS for these motherboards might not arrive until January. 
If you have a 500-series you'll have BIOS updates ready now. 

On the other hand, regardless of which series motherboard you have, it will take 3000 series chips with a BIOS update. There will be plenty of 3800X, 3900X and 3950X chips on the second hand market shortly. 

I have a Asus rog strix b350 motherboard so not really a new one 😕

Everything has come to a halt...

https://www.techspot.com/article/2114-amd-b450-or-b550-motherboard/

From what im reading on that chart.You need a new Mobo (Unless you are getting a 3000 chip with integrated graphics) . Also another fun fact. Zen 3 5000 is the last AM4 design before they change the Chip socket again. so If you buy a B450/B550 motherboard as a ticket to get a 3000 or 5000 CPU your looking at a new Motherboard again down the line if you decide to get Zen 4 when it gets released. For some thats not a big deal because they will hang on to their systems for a few years. For others they may want to have an architecture that is new so they can just drop a new chip in with a bios update.

Intel is releasing Rocket Lake in the first quarter of next year so it may be an option depending on what you decide to do.

 

Decisions decisions.

Cheers

Thanks, 

 

For sure if I go for the 3900x I'll take a b550 with it, but first I'll wait till the patch and then start negotiation with wife if I need to upgrade 😄
