Well, what Ive been noticing IF I dont use Vsync in MSFS I get tearing. Now If I turn my frame limiter off I can get about 45 frames at average pay airports not LAX or large onces.But have I have noticed if I set my frames to 60 and turn on gsync yes its really smooth but U get these micro stutters that I dont get when Vsync is turned on and locked at 30. I have tried so many different settings with in the sim and watched almost all MSFS related video in YouTube on performance and graphics settings. My monitor has a 75 refresh mode but I dont use it and leave it at 60. The monitor also has free sync which I would assume is like Gsync. Yes I have 500 but Im still saving I know the 4 series are alot more.

Plus I get a HUGE frame drop with AIG, or FSLTL using those injectors. EVen with IFR traffic set 0 and VFR to 0 and just using static set to 2 with Vpilot for Vatsim there are moments I guess when some traffic is loading in or if a vatsim player is populating where my frames go from 30 to 15 or 20, then it settles down back to a solid 30 in 15 seconds.

 

For frame counter I use rivatuner

Why not get a 4K display? Then a 4090 or 4080 makes sense. 

Okay I just purchased a 5800x3D. Read a ton of reviews before making that decision and it seems that this CPU does work so much better in Microsoft Flight simulator. May have a little bit of a slower clock speed than the 5900X however like mentioned in this topic the cache makes a huge difference

If your monitor is gsync and you set an fps limit in nvcp around 40 it will pretty much eliminate the stutter because your system is capable of keeping up. You stated above that fps unlimited yields around 45 fps, so setting limit at 60 fps is beyond the ability of your system. That's the beauty of gsync - you're only limited by the max refresh of the monitor. You can set fps limit anywhere that is within the ability of cpu and gpu, but below max monitor refresh and you should have no stutters. The key is to pick a reasonable target - don't set fps limit that matches what your system can do at simple airports with a light GA aircraft if you normally fly into complex airports with PMDG or Fenix. Make it a limit that you can achieve without stutters in the scenario you most frequently fly.

The best way to find the target is to use dev mode and watch frame-times for cpu and gpu. If you want 40 fps, frame-time needs to be 25ms or less, ALL THE TIME; for 60 fps, 16.7ms - any time frame time is higher for cpu it will stutter - if frame-time is higher for gpu your fps will go down, but it shouldn't stutter because gsync will just sync to higher frame-time of the gpu.

Thanks. Seems to run good at the moment with half refresh rate set in MSFS since the refresh of the monitor is at 60mhz

It's a tough one, I tend to agree with @Ricardo41.  I have been tempted by the 4090 and have backed away from the edge a number of times 🙂 I'm at 1440p with 50-60fps in cruise and 30's on approach/taxi so when you consider all that, it's probably a waste of money right now. 

Don't forget: Nvidia want us to be dazed and confused with all the marketing BS. It's not like Xbox. They exploit the fact that PC systems are infinitely different and bombard us with ray-traced DLSS videos of Cyberpunk 2077.

Ok installed the 5800x3D. We'll have to play with it a bit longer see how it goes, I do however notice it takes a lot longer to load the MSFS and it might be due to the slower clock speed. But let's see how this extra cache performs. 

Did a flight from KPHX to KSAN with the PMDG 737. Yes the sim seems to run smoother and more fluid. More frames? Hmm idk, I still got the frames dipping to 25-30 (locked at 30) touching down into KSAN which ruins the emersions when there are stutters like that during the rollout. All in all will still tweak a little more. My settings in the sim for TLD 100 and OLD 100

Hi Bill,

There's something between 1080p and 4K:  3440x1440, a big upgrade over 1080p.   Higher screen resolution does not only impact the GPU it impacts the CPU to some degree as well.  When deciding on screens always consider viewing distance:  the closer you sit, the more relevant resolution becomes.  In terms of "tweaking", look here:

My 3080Ti never gets anywhere near stressed at 3440x1440, and I suspect yours won't either even at that resolution.

I run at 1080p and get those stutters on landing.  You saying I should increase the resolution?

Nope, but at 1080p and your new CPU you have ample processing power to run w/o stuttering, provided you're not running out of VRAM, and at 1080p I doubt you will.  This being said SU12 seemingly introduced stuttering in odd contexts that I haven't seen for many months since following the optimization scheme in the link I posted above.  It may be an add-on not sure.

I'll have to see what is causing those landing stutters. I know I use FSLTL for static planes set to 3 st airports. I set 0 for IFR and VFR.

Open DevMode and see what's being hammered--if anything.   This is one of those odd contexts that I have seen since SU12 where there is ample CPU/GPU/VRAM headroom yet sudden big increases in frame time variance and stuttering.  Either an addon or something SU12 that is muffed up can't tell yet.

Don’t forget to install the latest AMD chipset drivers. 

Something is not right..

I am running a RTX3070 at 1440p with settings all at least Ultra. Some (such as LOD) are a bit higher than Ultra.  DX11 and TAA .  45 to 55 FPS most of the time. Stutters are rare.

The rest of the system is a 9900K and 32GB RAM.  My bottleneck is the 9900K.   With a better CPU I would be looking at better than 60 FPS at 1440 P from the 3070.
