I left P3D a few months ago as I was fed up with the sinusoidal performance of my sim - one flight it looked amazing and then the next flight I suffered from slow loading scenery textures and micro-stutters. Switched to DCS and kept my passion for simming going. Reinstalled v4.5 there last month and accepted it for how it performed. Along comes Xplane vulkan and P3D v5. Great, time for smooth flying finally right? Only one sim is delivering that and its not v5. 

Default aircraft in P3D v5 (tested Cub and coupled with Orbx LC + region. FPS is good (expected with no add-on). Nothing but micro-stutters in external views and scenery textures constantly loading in as I fly around. PC specs should not be an issue. I can run other Direct X 12 applications with zero performance issues. As a test I've turned sliders way down to left hand side and tried HT ON/OFF and still the same issue. v5 should not be scenery popping with sliders almost full to the left. I keep on top of my hardware and keep applications to a minimum on my PC. v5 should be performing better.I will be trying a fresh installation tonight and failing that it will be a refund for me. But even stating I have to reinstall is not a great start on my relationship with v5. Disappointing. 

Well it works for some and not others.  Sorry for the issues you had, stay well and maybe see you when MSFS is out.

Lets hope that re-installation works ok because it is the extreme opposite of what I have been getting.

Microstutters are probably the thing I am NOT getting and I only have a lowly GTX1060 for now. Not sure what your specs are though to warrant such poor performance.

 

Not so sure that MSFS is going to be the holy grail and all things are going to be utopia either.

I would not totally bank on MSFS as it will surely bring its own inherent issues.

That is my concern too. I want v5 to work. Lets see how the reinstall goes.

Did ou start from scratch?

I’ve been fiddling with v5 the last 24 hours or so as I really want it to work. I’ve managed to get High FPS by playing with the sliders and placing them at respectable positions. 
now my issue is the same as yours. My install is vanilla.

as I fly around, the scenery pops in and out under the plane. This isn’t due to my pc not being able to handle either. It just looks like a limitation of the sim itself?

What are you doing to address smoothness in game play. Are you using a monitor or a TV? What is your display refresh rate? Where are your sliders? What is the FPS you are seeing. etc

G-sync monitor 35 inch curved here. 
move sliders down to about medium level. Ish. Monitor refresh is 100hz. 
fps are 70-100. Capped at 100. 
It does seem smoother now. But say, when a major city swings in to focus, you get the stutters for like 1 second whilst it loads ? 
 

oh and also, popping scenery below the aircraft, and popping autogen. Not a lot, but it’s there

Hmmm, That's kind of an atypical setup for Flight Sim. When you are reading posts about how silky smooth it is from other users bear in mind that they are probably nearly all using a TV and have there monitor set to 30hz with Vsync. So what they are seeing in there FPS synced to their refresh rate which equals smooth game play. Your Gsync montor will adjust the refresh rate to match your frame rate on the fly. I'm just spit balling here but the Frame rate in P3D can be very erratic which might cause problem for gsync. with that setup can you change you refresh rate in NCP? If so try 60hz. Then in the sim lock your frame rate to 60 and make sure you have the setting low enough to deliver 60fps constantly. If you can with that setup try using Vsync instead of Gsync just to see if you get any improvement.

Thanks. Been fiddling with v-sync and g-sync the last day or so. Anything below 30fps is chaotic. Anything above and below 100fps is smooooth! With the exception of scenery loading. It’s more to the fact that, it takes like a split second for the scenery to load in during a high speed turn? Which creates the stutter. 
Also, what’s with the autogen popping? 
 

Anyways, the experience compared to the other day is 75% better! If I can get rid of that mini stutter and popping autogen, it will be golden. 

Well that was interesting, after reading some of these post, I decided to go back to basics and remove my frame limit on RTSS  and then totally uninstalled Riva Tuner.

I then set my limiter to 60fps and removed the 1/2 refresh rate in the driver settings which I have using in V4 for donkey's years and has served me well. The slight screen tearing I had with V5 has now gone, so does that mean the limits may be holding back V5, not sure. I did read somewhere that the RTSS frame limiter has caused some issues with v5. Not sure

 

One this is for sure, since V5 has come out, I am totally profficient in landing this fighter jet 😁😁😁😁😁

Short video captured showing scenery popping and stutters. Settings on very low.

Going to try and reinstall this weekend.

There are a couple issues going on here that are worth pursing that I think may be side effects of v5 providing higher framerates...

With respect to popping, it is possible the CPU needs more time to render terrain/scenery. In v4.5 when we had it locked around 30 fps, there was typically headroom left to make sure scenery/terrain rendered easily.  If you're now running at much higher framerates, especially with a higher anti-aliasing multiplier (4x or 8x), the CPU is using more cycles to run the sim than previously and has less resource available to render terrain.  One of the advantages of locking the framerate is that the CPU can use all the extra resource to render terrain and scenery.  The smoothest way to do this is by using vsync, unlimited frames and a 30hz screen. Some people, however can't set their screen refresh to 30hz, so have to use something like RTSS or the Nvidia framerate limiter, some of which worked fine in 4.5 but some have reported problems with them in v5, so I'm ignoring that for now, as well as messing with FFTF values.

To test the theory on terrain/scenery popping, try locking framerates at 30 fps and for this you can turn off vsync.

Note that by design, with frames locked, your core 0 (or first P3D thread) will be pegged at 100%

With respect to stutters with G-Sync and high refresh rate screens, I would try a couple things. First, G-Sync's minimum framerate is 36 fps (if I remember correctly), so I would try a couple things - first I'd try to lock frames at both 40fps and 50 fps and leave g-sync on for both of those.  Then I'd also try to turn off G-sync (it doesn't work that great with lower FPS environments like P3D, etc), manually set the monitor refresh rate to 50hz (it should be able to do that, or something in that range) and then I'd set frames in P3D to unlimited with v-sync and triple buffering on

The other factor that can be further explored for both of these concerns is whether we should be using the same approach to affinity in v5 as we did in v4.5.  My take is yes. So the most important factor there is to be sure that *IF* you have hyperthreading on, make sure you have an affinity set that doesn't allow P3D's first thread to complete with another thread on the same physical core, because that will dramatically reduce P3D's ability to run smoothly.  If you tell me your processor and whether you have HT enabled, I can suggest an AM to try..

I’ve set affinity 85? 9900ks@5ghz HT enabled 

I don’t have stuttering anymore. Just sometimes popping scenery

Positive progress.  With 8 cores/16 threads, your affinity of 85 is only using 4 threads, so basically only 2 for scenery rendering.  That might explain the popping. I'd go with 01 01 01 01 01 01 01 01 which is 21845 as a starting point.
