What CPU is the best CPU available that is needed to avoid CPU bottlenecks?

Thanks for the tips.

So here is more info on the setup and the results.

I had built this PC as a start into Flight sim 2020. I am basically a Mac User since about 15 years and had to get a PC now because of the FS 2020.

MSI MPG GAming Plus
AMD Ryzen 7 2700X
32 GB Corsair VEngeance
MSI Radeon RX 5700 XT Gaming X
1 TB SAmsung 970 Evo M.2 for the System and the Manual Cache
1 TB SAmsung 860 QVO for the Apps

I am running two Monitors, LG 38" ultrawide in 3840x 1600 although playing the game on one in fullscreen, using the other one for webbrowser, google maps, the com with flight control and IFR.

Used your tip with the developer tool.

Framerates are not that good and limited by the GPU

Mid Setting: 26 tp 28
HIgh: 19 to 23
ULtra: 17 and lower

this was in flown in the Twin Cities Area and the data/terrain preloaded in the manual cache.

NOw I have read here, but not sure if understood right, that FS2020 does not support two video cards? Because that was kinda my thinking, to exchange the Mainboard to one which can easily host two cards and get another RX 5700 XT.

Although in light of the new NVIDIA, I just might wait and get the 3090.

Greetings and thanks for your tips

Christian until you get that Ultimate Unobtanium RTX 3090 I suggest you do two things:

  1. in the fs dev fps tool note the actual ‘milliseconds’ for main thread and gpu. In your case the gpu will be the higher number and your fps will be a bit less than 1000 / (gpu milliseconds). FWIW 1000 / (main thread milliseconds) gives you a clue where your cpu limited fps would be of you weren’t limited by gpu.

  2. Set your ‘render scale’ setting to 70. This will reduce the resolution your scenery and cockpit be rendered at but the UI will still be at full resolution and it might be better than you expect. That should radically improve your fps.

Basically now you can look at your (reduced) gpu milliseconds, main thread milliseconds (which won’t have changed much), the limited by gpu/cpu hint and the (better) FPS and experiment on from there.

The good news for you is there are a lot of settings that can be turned down to reduce the load on the gpu (e.g. clouds, trees, reflections) but the cpu is harder. But start with a big change to render scale to get an early clue to what’s possible.

One thing I’ve seen (I just upgraded too), is that I get really solid performance at 1080p resolution.

I have:
i7-10700k
RTX 2070
32 GB RAM
NVMe 1TB m.2 drive for simulator

I get really solid 60 fps plus with limited bottleneck on the CPU. I am using “high end” graphic settings without tweaks. The GPU actually pings occasionally but rarely. It seems it is known this game was designed for future hardware.

MSGamer is right that you need to adjust what is GPU vs. CPU limiting.

Well thank you. I will take a look at those numbers as well. I appreciate the help.

Overall I am still satisfied with the whole app, of course we all want to achieve a certain “optimum” right.

Just done that, calculated and reduced the rendering settings to 70.

FPS is up to 34 to 38. In the beginning of the flight the limit is the GPU, but after a minute or so it changes to the main thread.

I guess I will have to see and wait until the unobtainable gets obtainable and payable. Then we go from there.

Hello, how is the usage on that 16 threads? What is your smoothness index? :yum: Would love to here some more from your experience regarding that topnotch cpu… How you are driving it? All-Core OC?

Just wait for Zen 3 in October. It is supposed to open a good lead in IPC over Intel and take the gaming throne. I do like Intel, but it seems things are changing.

So I would not spend any money on an Intel 10th generation. They might get blown out of the water next month.

Just be patient.

Two graphics card is rapidly becoming something you only do if you are playing with machine learning or running genetics/statistical software. It never did help much in workstation apps like Autocad and it always was a bit esoteric and hit and miss with gaming and the support for it is dwindling rapidly.

Nice results me thinks.

The next version.

Hey! What kind of performance increase did you get by upgrading your RAM? I have a similar setup to you. I have 4 x 8 GB of G. Skill TridentZ 3000mhz RAM and was curious if an upgrade to 4000mhz RAM would be of any benefit.

Thanks

Ah my old account. Surprise this thread is still open and in fact ended up upgrading to a faster CPU did not make a big difference.

I doubt going from 3000mhz to 4000mhz ram would do much, maybe a few percent. The sweet spot seems to be about 3200mhz. At least this line of thinking is because of J2C videos where he tested ram speed from 2133 up to 4000 and there were pretty large increases from 2133 to 3200, but not much of anything past that.

With regard to ram speed, with AMD the RAM speed can limit the CPU whereas Intel have an external RAM controller so it has a lot less effect.

TLDR -
AMD the speed of your RAM can matter a lot
INTEL not so much, in fact nada difference in most cases

I think Tom’s Hardware was seeing some 4-6fps gains from 3200Mhz to 4000Mhz in MSFS back in the release.

I would try to settle at least for 3600Mhz with very low timmings.

I’m happy with the 5900x get good performance coupled with 64GB ram and rtx 3090

Can you get min/stable 30 FSP at ULTRA 4K at all heavy load sceneries with this rig ?

I have 5600X and RTX3070 and planning to switch on RTX 3090 + 5900X like you. I just want to get 30 FPS stable at every point on earth with airliners. Would you recommend this setup as enough ?

I will run some tests tomorrow but I would think so, I don’t monitor my fps I get Lagg free experience with no stutters all on ultra very smooth experience

I will have to setup my 4k monitor as I recently switched to ultrawide but the performance was the same before the switch.

Performance is the same if I’m running stock speeds or if I’m running any overclcok typically I will run at 4.5ghz on all cores

Thanks for the response. I would definetely go for RTX3090 in mid term but a bit doubtful that do I really need to switch my 5600X to higher one like 5900 or 5950. It would be great to hear from someone else. Can you test with handcrafted/addon airports and airliners ?

Kind regards.

I just swapped out my I7-7700K for an I9-11900K with a new motherboard and 360mm CPU cooler and have noticed a pretty big difference.

I think that keeping the CPU cool, whichever one you have, makes a big difference in performance. Especially extended performance.
