High FPS Low Smoothness

Recommended Posts

I’m running an i7 7700k, overclocked to 4.9GHz, 1080 TI Aurous Xtreme, with 64 GB DDR @3200. My monitor is an Acer Predator x34 Gsync 100hz. I have Black Marble Base and Vector, Pilot’s FS NG Ultimate Mesh, practically all of Orbx’s products. I’m running an affinity mask of 116 tweak. Although I get relatively good FPS, noting below 25, and maximums of about 80 FPS, the experience isn’t smooth, even at high FPS. How can I get rid of stutters?  Any suggestions will be much appreciated…

 

Best,

If your FPS is fluctuating a lot that might do it.  Try locking your FPS to something you can always maintain and experiment with vsync on/off especially if you can run a monitor down to 30hz.

Lock your FPS at 20 or 30 and start from there. As you have found out, high FPS does not mean smoothness.

Thank you for the advice. Although very briefly, my FPS drops to less than 20 while on approach to EGLL with Orbx England installed. Besides this, it’s almost always above 30 FPS, even at dense city centers, flying VFR. So, will it be ok to lock my FPS at 30, even though I cannot always maintain it indefinitely? I have experimented with V-Sync and triple buffering on and off, but haven’t noticed any difference. Is it because I have G-Sync? Also, why do you recommend that I run my monitor at 30hz when it is capable of 100hz with Gsync?

 

Kind regards,

Thank you, Vic. I will give it a shot and hopefully will make things smoother. 

Kind regards,

Maintaining your monitors refresh rate with vsync on usually results in a smooth experience.  I myself run it down to 25hz and as long as I maintain 25 FPS it's perfectly smooth.  A lot of people have success with 30.

 

Also London is a black hole for FPS.  I have to back my settings off quite a bit when flying there to maintain reasonable FPS and I don't even use the ORBX region (but I do use global/vector and have Aerosoft EGLL).

How do I limit my monitors refresh rate? Do I have to set it in the prepar3d.cfg file? Regards,

Also Orbx England is really hard of everything you're much better just using OLC. Orbx England is know as not there best regions for performance.

Yes thank you for confirming, isn't there a website that provides reviews, about Orbx's region performance?

Try their recommendation about the shadow receive tweak; it helped me out...

Lock your frame at a level that match you 100hz with vsync and triple B ON. 

I have 120hz and lock mine at 24 (120/5) FPS+1 with your 100hz I would try 25 (100/4)FPS+1. 

The +1 is because you never get 25 it will always be IE 24.9 so always add 1 So for you 26 FPS you will see it shows around 25.7-25.9 hence your at 25....not a true 26.

Disable Shadows in your config file, for details check out the BM support forum.

For a quad CPU with HT on, you can also try some AffinityMask settings to avoid conflicts with other processes that are running on your system.

In sparse scenery, this all does not matter, but in dense scenery, here are some settings you may try.

For me, getting P3D off the first physical core and giving it the second core all to itself improves smoothness (244).

[JOBSCHEDULER]
AffinityMask=244
// 244=11 11 01 00
// 245=11 11 01 01
// 246=11 11 01 10
// 253=11 11 11 01
// 254=11 11 11 10

You're running a G-sync monitor, no reason you should have to set a locked refresh...it's will sync refresh to fps, even if it varies.

Locking fps in-sim will help keep cpu management/loading of scenery from lagging behind the rendering capability of your GPU. Even with the current fastest cpu's, there will be times that it can't manage scenery as fast as your GPU can render, so you get a skip, or stutter. Just do as Vic says, and lock fps...with your system, I would try 30, and 35 and see which you like best. As you already know, there will be times you can't maintain 30, or 35, but that's caused by heavy scenery load on the cpu. 90% of the time, however, your system will be able to stay at or above 30, or 35, and during those periods it will be silky smooth.

Make sure that in Nvidia Control Panel under "Display - "Setup GSYNC" is set to "Enable G-SYNC for windowed and full screen mode."

With your G-sync monitor, the one thing I WOULDN'T do, is use a fixed refresh rate...defeats the whole purpose of G-sync.

I also run a G-sync monitor, and it's made managing settings to achieve smoothness so easy...all I have to do is set a fps lock in P3D that I can maintain MOST of the time and G-sync automatically syncs refresh to match.

Considering that you run a reasonably fast system, I'm assuming it includes some flavor of SSD? If yes, do as I've suggested, if no...GET ONE.

I get the desirable smooth micro stutter free sim only when the system is able to consistently produce 60+ fps at a location on my 60hz display. In high detail places mostly goes low 15-20 fps, going by that will have to wait for a cpu at least 3-4 times caliber than current 4790 no oc unless something substantially changes about p3d multi coring. 30 fps doesn't do it with its movie like motion fluidity, and the p3d micro stuttering doesn't seem to go away until high fps regardless of reducing the various settings.
