Double Performance With A GeForce RTX 30 Series Upgrade

[iFlySimX 751]

That is so FALSE! I went from a 1080TI to a 3080 and at 1440p with same high/ultra settings I only saw around a 1.5X improvement....not 2x. Also, at this point my i9-9900K gets "limited by main thread" in MSFS. So to summarize, you can have a BEAST of a GPU but it will only get you so far. MSFS 2020 is still CPU bound (Very sad, we are in 2021 and that's because they brought code over from FSX.)

I'm glad I picked up an already overpriced 3090 over a month ago, now it's over $1000 dollars more than I paid. Unbelievable. 

Same here. I thought I overpaid for my 3090, but now they're going for 20-30% on top of that. 

The RTX 3080 on the used market is what 3090 was just a few months back. Insane.

That seems fairly consistent with their results.  The improvement at 1440p will be less than at 4K, a 1080Ti is more powerful than the 1080 they compared against, and your CPU is slightly lower spec (9900k rather than 10900k) meaning you are more likely to be CPU-limited.

I am limited by main thread also when I fly in over buggy areas, it has to do with the bug in SU3, I was Limited by GPU the whole time before this patch.

What I don't think anyone has spotted is that it says on the chart '80% Render Scale' which is not true 4K. This is probably why it manages to gain double the fps.

I was lucky to get a 3060Ti in an NZXT build about a month ago.  It is a great performer as I get 37fps at 4k and runs at a cool 200 watts..  The 5900x just lounges at 25% mostly.

MS Flight Simulator (2020): the 2021 PC graphics performance benchmark review - Article - Guide - Review (guru3d.com)

What Nvidia says and what the testers say on real benchmarks. a few frames more at 4K.

[knich 113]

I have the 3090 and I had the 2080ti.  I'll have to see exactly what settings they are using to get 60fps...but it begs the question.    I can easily get 60+fps with basic sim.  But with the multitude of addons I have and playing at 4k no way.  And there are plenty of microstutters.  So what settings are they using is the question?

[Glenn Fitzpatrick 3,798]

I think the Nvidia results are sort of high-ish but legit in scenarios where the game is GPU bound.

Yes most people are CPU bound even on a 1080 unless they running LN2 and maybe even then 😄   -  but they are doing what most online product reviewers do and removed the CPU from the equation and directly compared the two cards in a scenario where GPU is what matters.

It is marketing spin but not really dishonest =  they are probably genuine figures for a non-ti 1080 versus a 3090 in scenarios where the CPU is not an issue.

Not to the extent P3D was as far as starting w/ pure FSX code.  MSFS 2020 isn't CPU bound per se--it's all relative to the specific CPU and GPU involved and specific scenario you're in, as it is in P3D and FSX before.  For my 9900K at 5Ghz on all cores it's absolutely always GPU bound, because of my lowly 2070 Super.  DX12 port should change the details as well.

For my 9900K at 5Ghz its limited thread...

Would it really make a difference to upgrade CPU?

The 9900K is end of the line for the 1151 motherboards.  Also the 9900K is still in the top half dozen CPUs even now so whilst a newer one will make some difference,  I doubt it would make ENOUGH difference to justify a new motherboard, potentially new faster ram, and a new CPU.  Whilst the 10900 's  and the new AMD both have more cores,  that is not a huge benefit in the current game and even a 5% faster clock will translate as just 40 frames versus maybe 42 FPS in game if your lucky, not worth such a major upgrade in my opinion.

If your on a Z series motherboard make sure MCE is enabled.  Also WRT the 9900K some people talk about turning off hyper threading thus allowing higher single core clocks.

Next iteration after 9900K is good for ~3% increase in single thread performance over 9900K at the same clock speed.  So the answer to your question:  not significantly.   If you want the most out of your 9900K/RTX 3080 then be sure to not demand of it more than what is required to deliver fluid, stutter-free performance at not more than 30fps.  The method that delivers on this the best is to vsync to a 30Hz capable screen.  Both your CPU and GPU will breath a sigh of relief.  Here's an example of what I mean.

This one was done with all sliders on Ultra (except one or two shadow-related were down one notch, LOD 200/200 RS 100, vsync'd to a 30Hz screen.  3D performance is a totally smooth 30fps, and voila there is some serious headroom left in this scenario, both in the CPU main thread (CPU16) and also in the GPU:

:\

Below is the identical scenario, however is now unlocked and delivering as many FPS as possible.  Note the main thread is now almost doubled utilization, and contributes to the frame rate increase from 30 to 41, while the sim is now running GPU-limited at 99% up from 76%.

The take home message:  I guarantee you 1000% you would not notice the 41fps was in any way better, in fact it brings in stuttering which the vsync to 30Hz does not manifest.  Note how cool this hyperthreaded 9900K is running at as well, air cooled.

My sense is the entire obsession for more FPS is misguided, at least in terms of getting the best experience out of your hardware.

This is important. Many newer 144hz gaming screens have a  minimum refresh of 48hz (one third of the maximum) so just setting vsync on these to 30 hz is going to cause issues unless you have either gsync or Freesync 2 running .   Ironically a generic 1080p 60hz budget gaming monitor will be fine.

Sorry, slightly off topic but Noel what software do you use to get your fps overlay ?

I've seen that overlay on several games and programs but always forget to ask what program is used.

Thanks
