Question for you all... If you had to pick 1 or 2 settings within the sim that affect the performance of the sim for better or for worse what would that be?  Probably an open ended question but thought I would get your feedback.  Merry Christmas!

1) Terrain LOD for the CPU

2) Resolution and resolution scale for the GPU

If i have some stutters, would that be more of a CPU or GPU issue?

Depends, but on my end Ryzen 5 3600 runs over 80degrees whereas my 1060 gpu runs some 50 to 60degrees.

I would say TEXTURE RESOLUTION.

Most leave it in ULTRA, but this brings stutter in big airports and complex planes, as it easily surpasses 8GB of VRAM in many cases.

Would you say there is a noticeable difference between ultra and high in terms of visuals and performance?

Be sure to go into Options > General > Developer and enable its frame rate counter while dialing in the best settings for you--it has several parameters to view to help you ascertain if the CPU main thread is the limiting factor, or GPU is the limiting factor.  Then play around with various settings until you get something you are happy with.  As mentioned Terrain LOD has a very big hit on the CPU mainthread, and resolution/rendering scale on GPU.  Of note, setting Render Scale on 100 = keeping the output to your display the same as what resolution you set.

Also, if you do not have a G-Sync clapable display set your display refresh rate at 60Hz, then use Vsync ON in-sim, and set frames to 30.  This will give you your best shot at stutter-free, once you've dialed in settings so that you can maintain 30--and it is critical for Vsync to remain stutter-free to keep frames at >=30.  If you have a very weak system you could actually get more graphic detail by setting the frame limit to 20 in-sim, w/ Vsync ON, but you're of course more able to perceive a frame rate of 20, but it's not out of the question for some and free to try.

Stutters are due to CPU or I/O access (mass storage reading).

 

If you're GPU limited at a higher resolution, one of the biggest settings you can try for a performance boost is render scaling - try somewhere between 80 and 90% on a 4K screen.

Yup, try and install the sim on a fast SSD / NVMe drive, and play around with the rolling cache on or off. Could also be network, particularly around photogrammetry.

This only applies to GPU'S with not alot of VRAM and as a result would be a secondary setting to tinker with. A simmer can still have cpu related stutters on a very mismatched or mis-configured system and have more than enough VRAM to accommodate the texture resolution. So as far is i see it the primary sliders to adjust roughly would be the ones MR fuzzy Mentioned.

After that you can move to texture resolution ..

Apart from Terrain LOD and Resolution it is Volumetric Clouds that takes most performance hit on my computer.

The setting that reverts the sim back to SU4 code.  The best combination of performance/LOD's/visuals - it's been downhill ever since. So much so we need an entire SU8 dedicated to "bug" fixes.  I truly wonder sometimes whether we will ever get that solid platform back.

I hear you, but, don't you remember what it was like originally? I mean, how it was actually like? It was awful. Don't you remember night lighting? The apocalyptic photogramatry? We didn't even have fog until this latest update. Turboprop logic has vastly improved. We couldn't even taxi the 787 or 747. Yes, there is still a huge amount of work to achieve what we want, but we're so much better off than we were a year ago. Sure, the tree distance thing kinda sucks, but overall, I think the sim is doing very well. SU5, even though it only had good intentions, did break quite a few things. BUT we did see a huge performance gain. They listened and gave us a higher LOD slider, which if you set to 400, will destroy performance. Clouds did look better earlier on, but I think they are focusing on DX12 rendering now, so there's no need to polish a word not allowed. I think this pseudo nostalgia comes from the marketing trailers, not the actual sim. I just think that we need to have a grounded interpretation of what has gone on and what is going on. I want the final product as much as you do, but to say we should revert to SU4? No way. I'm not trying to single you out, irocx, it's just that this sentiment has caused an uproar in the community, and I'm on the other side of the aisle with this.

Performance is much better now than in SU4, where everything was on the main thread.

The only good thing that SU5 brought was the glass cockpits elaboration on another thread, with a massive framerate increase in airliners cockpit view.
