Hi!

I'm really interested in how you guys are handling your frame-rate-limit? 🤓

Unfortunately I'm not able to run my monitors on 30Hz and just use VSYNC, as I would guess this is the best option to handle the frame-rate-limit.

So I've been using the internal limiter on 30fps for quite a long time and it was kind of ok.
Then I switched to RTSS with the scanline sync option and internally unlimited, which felt a bit better.

But it would be nice to see what works for most of you 😎

Cheers,

Marc

Latest drivers allow for vSync off without tearing, but I still have it on. P3D locked at 33 for smoother panning. FF at 0.15.

MSFS 2020, what an amazing sim!

Technically, there should be a "No Limit" option for the second question.

I use Vsync and TB on with unlimited and my refresh rate set to 24hz in NCP. With that I use TrackIR5 with a custom profile with the smoothness set to 50 with precision tracking. On top of that I also use the additional smoothing feature in EZCA 3.1 set to about 700. Of course for this to work properly I need the actual frame rate delivered by the sim to be above 24fps. I aim for 30. I tried setting a limit of 30 to Frame Rate in P3D setting to rationalize frame rendering but I found that no mater what I set Frame Rate too other than unlimited in the P3D setting I get some long frame stutters and occasionally a burst of micro stutters. With Unlimited the sim is virtually perfectly smooth.

Unlimited in-sim (v-sync off as well), i use nvidia's control panel to enable fast v-sync which, in my case, provides the best smoothness while maintaining high (50+fps) frame rates without any tearing.

Shocked at how many are using the sim's internal framelock.

That tends to slam Core0, which historically isn't a good thing.  I wonder if v5's reservation of extra overflow cores has eliminated that problem?  I can't imagine one-third of simmers using the internal framelock with bad results.  They must be getting smooth stutter-free flight that way somehow?

I can't either. I gave it a good go locking to 30 fps with 30hz and FFTF=0.1. Even with setting that delivered well over 40 fps with Vsync off and Frame rate set to unlimited I see long frame stutter and the odd burst of micro stutters once I turned Vsync, TB on and limited the Frame rate to 30 or 31. Once I reverted back to Unlimited Frame Rate those stutters completely disappeared. Only I suspect that with Unlimited frames the autogen loads closer the aircraft than it does with limited frames. (I'm not sure about that. Will require further testing). All things considered Prepar3D V5 is awesome. It's a huge improvement over V4. Particularly and almost entirely because of TrueSky. I need 20GB of VRAM please!🤪

What is the recommended external framerate limiter?

Very smooth with internal limiter at 30 HZ and monitor at 30 HZ,  Vsync on inside P3D.  Monitor is a Dell 4K 32" (60 Hz native) with 1080ti 11G Vram,  Still on P3D 4.5 though.

Unlimited/Vsync Off in sim and NCP/NVI framerate (I use both) set to 28 for my 60Hz screen.

What's the reasoning behind this? I have a 60 hz panel also.
