Hey everyone - Happy New Year! 

I was hoping to get your help on trying to tweak my MSFS to deliver decent frame rates on a fairly good computer. Currently I can only get 25-35 fps regularly while flying and if I'm at a busy airport like Heathrow, my fps is 15-25 while looking around the cockpit. I'm currently only flying at 1080p to try and reduce the demands on the computer, but that doesn't improve FPS majorly. I am running default graphics specs on high

It appears as if I'm main threat limited (see screenshot in link below), but my GPU / CPU utilisation is only ~30%. I get a similar sort of perofrmance when I fly smaller aircraft like the Cesna (drops to 25 FPS when looking around the cockpit). 

Are there any graphics options I should definetely tweak down to meaningfuly improve FPS? Specs of my computer are:

- Ryzen 7 3700X 
- 16 GB ram (3200 Mhz) 
- Nvidia RTX 3070

- M.2 500 GB 

Thanks in advance!

Hi there and a Happy New Year to you too

Here is a very good video to watch where you can make decisions what's important for you and on which settings to compromise. And of course you have to keep in mind that busy airports and airliners are not really fps friendly:

 

Here is another helpful link: https://forums.flightsimulator.com/t/how-to-graphics-settings-and-performance-guide-su5-complete-retest-8-2-2021/132407

You should run the sim with your native monitor resolution, if that's a problem just reduce in sim with render scaling.

 

Hope this helps, take care

Hi, Happy New Year.

We are all on the same boat. The low CPU usage you see is the average on all cores, but as you noticed there is one which acts as the bottleneck.

In order to improve CPU performance you can lower terrain LOD and traffic, which are the settings that impact on it the most.

In the meantime feel free to increase the other graphics settings because your GPU can handle Ultra at1080p resolution without performance degradation.

If your MB / platform allows, replace the CPU with a Ryzen 5900X which is much faster than the 3700X. Really worth the money.

 

The Ryzen 7 3700 X looks to be broadly similar to the Intel i7 11700k specs wise. I may be wrong of course but I can't believe your rig can be that different. Note I am running SU7 public beta.

I have the 11700k - with 3Mhz memory, overclocked to 5GHz with an old GTX 1080 ti graphics card, also overclocked. I run MSFS at 1440p and have been getting 30+ FPS at large airports (e.g. mod add-on EGKK Gatwick) and 50-60FPS in the air with the eg CJ4 or King Air across UK and Europe. So it seems like you ought to be getting something similar, at least from the spec. My settings are HIGH to ULTRA; Terrain LOD at 200 and cockpit on HIGH. 

In terms of main thread I am seeing latency around 10-20 ms on my CPU at about 25-30%, with 15-25ms at 95-98% on the graphics card. If these readings are too different that can cause a bottle neck. You don't give the latency reading in your sim. Worth going into Dev mode and having the FPS monitor running whilst you test your settings,

The advice here to watch videos about optimising your sim and PC settings is sound. I had to do a fair amount of optimisation to get a smooth stutter-free experience  - with advice mostly from the MSFS forums and YouTube.

Hope this helps - good luck.

No, it's much slower... it can be compared to the 8700K with 2 more cores.

The 9900K was already faster than the 3700X.

3700x is more of a mid range CPU.

Maybe @Ricardo can share some insight - I think he runs an older pc.

Fuzzy is right, the best you can do is to lower terrain LOD and traffic until you get rid of main thread warnings, all the other settings you should be able to run at Ultra with your graphics card, in addition to upgrading your CPU, it is also wise to upgrade your ram memory to 32 gb at the same time.

OK, I'm somewhat puzzled- you say it's a lot slower than the 11700k. OK fair enough I'm running at up to 5GHz which is a bit faster - the 3700X can go up to 4.4GHz overclocked

But I used to have a 2014 vintage i5 4690k before this, running 4.4GHz OC at 1440p - . I was still getting 25-30 on the ground and 40-50+ in the air after SU5. So how could a current AMD be slower than that? I remember getting 30-33 over the City of London for example. Lot's of people with older machines are doing perfectly fine on MSFS up to 1440p and certainly at 1080p.

Perhaps I'm missing something here - if you are running at base clock 3.6GHz ok it will be slower. But surely that's the same as my current CPU at base clock.. I'm just sure he could be getting more out of his system.

Anyway for sure I know nothing about AMD PCs  There must be others who are running similar configs. I'd be interested to hear what they are getting.

See my sig - the 5900X is the way to go and a 3070 ti and above is a good GPU paring.

I think it's because of how the CPU's score for single thread performance.  MSFS still uses the main thread first imo.  I've got a 4790K clocked to 4.4GHz and it still holds its own.

Look at the 3700X vs my 4790K (at 4GHz)

For multi core he'd crush my system but for a single threaded app (not that MSFS won't use more threads - but I still say it favors single thread) - they're really close.

Hi,

If you are limited by the main thread or CPU then the problem can be that your video card is sending data too fast/often to the CPU. Actually, increasing the load on your GPU can in a roundabout way decrease the load on your CPU. You need to find the right balance for your system. Increasing the resolution to 1440, LODs, etc. is where I would start. Get it so that it flashes between limited by main thread and GPU both.
