Ultimate Smoothness at Modest Frame Rates

2)XPL 12... had half as much framerates, literally.

and only 1/4 framerate if you switch on FrameGeneration on RTX 4090 in MSFS, something XPL 12 does not have.

compared to RTX 4000 series with its frame generation, ....... those folks can brute force their way to Nirvana

just tried RTSS limited @ 40 fps, 4 K resolution on 60 Hz TV with NVidia RTX 4090 frame generation ON, VSYNC OFF, frame rate limiter OFF in NVCP.  total stutter mess. despite very even frame times.

 

 

RTX 4090 frame generation ON, RTSS frame rate limiter OFF : very smooth 83 fps.

obviously RTSS frame rate limiter and RTX 4090 FrameGeneration don't play nicely together, RTSS not needed, obviously.

How do you think it will display 40PFS on a 60HZ panel ?
This can only be done with stuttering.
Or use a VRR* panel which can adapt to the input FPS

I can't believe no one understands how Framerates work on a panel with refreshes 60 times per second.
30 FPS on 60 FPS is fine and other options also.
Some input settings will show stuttering because frames do not fit and will be dropped because of this. (stuttering)
 

VRR* refers to the way your TV adjusts its refresh rate to match the frame rate of the output device

no. I have been using my 60Hz TV at various fps values ranging from 25-60 fps, all stutter free, more or less smooth. It is the RTX 4090 FrameGeneration technique combined with RTSS framerate limiter that doesn't play together. but at 85 fps there is not much left to limit anyway. 😅

@Noel i think you have Hypertrading Off

Sure--the faster the frame rate, the less zero FTV matters so you're in great shape.  Cpt Piett did this test and proved using CapFrameX that frame generation w/ RTSS as I've described how to set it up produced significantly higher.  He didn't report any stuttering issues, he was just showing the FTV as I recall.  Were you sure to enable Edge Sync, and Passive Waiting in your testing?  

But really, this is only something worth pursuing if you can't address this with brute force.  All I know is I have perfect performance everywhere now it's amazing.  It is a combination of course in living w/in my hardware's means, but I tell you I have absolutely no reason to upgrade hardware at this point in time.  It wasn't long ago I was looking at starting w/ a 7950x3D, but there is no reason to for me now.  If n when Asobo amps up something like cloud depiction in a major way then this may come into play.

Yes you are correct.  In the past I used it in P3D and early MSFS, but there is no need to at this point in time as I have met my definition of perfection:  gate to gate, anywhere, in any plane, in any weather, with all settings at Ultra, T-LOD 130 on up, no stutters, no hiccoughs, pauses, shimmers, while turning, taxiing, observing AI aircraft.   GSX Pro's animation can do occasional hitches but that seems out of reach to fix for this user.

that's what I did, was tired after years of tweaking, snakeoil etc. I thought it was easier than all that process lasso thingamajig and instead hit that RTX 4090 BUY NOW button with brute force:

This used to work with frame generation (albeit with a lot of latency introduced) until the nvidia driver that fixed vsync for DLSS3. I used to use the exact same technique to lock at 40 fps in RTSS but get 80 fps in game. the affects were similar to what Noel is showing with a massive reduction in frame time variance.

Don't need to!  Already have PERFECT PERFORMANCE.  There is no further tweaking required.  You simply despite your tweaking and snakeoil never discovered how to do this.  It's good you had an alternative!

I did, but that didn't help much with VR, nor does DLSS 3.0 FrameGeneration. only brute force 2D rasterization power.

As you can see from the right scroll bar there are a slew of entries below the bottom of what you see.  The top processes are system processes that don't accept affinity reassignments so those show Cores 0-7, but everything below that is set at 0-6.  You can 'group select' these so very simple to do.  Technically you really only need to do the processes on the Active Process tab however this can change so simple enough to do all processes that might run:

 

 

 

Quick question, I have already assigned some affinities using Windows Task Manager, if I then use PL, would I first have to reset them back in Task Manager then assign them in PL to prevent a 'conflict' between Task Manager and PL ?

Thanks.

40 FPS works with 120HZ panel, if 60Hz panel, use 30FPS. Everyone has different standards here of what we think is "modest" "average" and "good" and rightly so. I have a 5800X3D and a 3090, but I run 4K, medium to high at a locked 30fps on a 120hz panel and it is stutter free. It's a game of diminishing returns the higher you push framerates and graphics quality, so you have to find a balance.

OP should keep up-to-date with people's opinion etc and we can have an all-in-one optimisation guide, although it does vary slightly for everyone though.

They should show up in PL as you set them in Task Manager. No need to reset.

No, when you set them in TM they restore to unset after rebooting.  So just reboot, then do you setup in PL.  I don't have PL start with Windows because it prevents MSFS from launching, at least on my system and at one other who mentioned this.  So I launch PL (w/ its configurations already set) after I'm pretty much at the gate.  Also, it can be shut down after initializing and all settings will be retained, until you reboot and repeat the procedure.
