60Hz monitor refresh rate questions

Recommended Posts

So I’m back with another question. I run Version 4.5 at 1080p with Vsync on and unlimited frames with triple buffering. My monitor is locked at 60hz. So this means that naturally, the frames in my sim are 60fps at its peak. I can usually achieve 60fps at a handful of airports, and at cruising altitude depending on the weather below, but I rarely see anything under 35. The thing is, I just don’t like how notchy my sim gets if the frames are less than 60fps if I pan around, or anything like that. Even if my frames drop to 50fps I still get stutters and notchy-ness. I understand that I can choose half refresh rate, and run 30fps, but even if I did that, my sim looks HORRIBLE. People claim they have a smooth experience at 30fps like silky smooth and I want to know how people are achieving this? Do I need to go buy a true 30hz monitor?? If my sim never drops below 35 at my current settings, plus add-ons, then I know if I figured out a way to drop my frames to 30fps and still have a smooth experience like at 60fps, then I’d be golden. And just to answer some questions, I am running a AffinityMask, and FFTF dynamic application. Not to get into a AF debate we’ve had enough of those. I wanted to know if there is a way I can get my frame rate down and still have a smooth sim experience.

You can go with a VRR monitor but that's not going to help with timeframe consistency (which is where "smooth") comes from (per my other post in response).  FYI, VRR is supported in P3D V5.x and some new job scheduler options that might help.  As I pointed out before you can see a list of monitors and their VRR range here.

Native 30Hz support by the monitor is the best approach ... are you HDMI or DP to the monitor?  FYI, TV's tend to support 30Hz because most content is either 24 FPS or 30 FPS and that's why "panning" is kept slow ... there are of course exceptions.

If you are using nVidia, you have NCP option to set "Max Frame Rate".  Alternatively you can us RTSS to cap frame rate.

But if 30 FPS is a problem for you visually on your current monitor, then your only real options would be to turn graphics settings down so you can stay at 60 FPS or higher.

Cheers, Rob.

As I just recently found out V5 works very well at 30hz, and along with upgrading to V5 you will get a nice performance boost (as long as EA is turned off). Something to consider.

I would if the aftermarket companies would catch up! How long has v5 been out? And many companies have still yet to port over their products. A big one being REX. They haven’t even attempted to make their products compatible. So as much as I’d like to make the move, I’m stuck with v4.5 until my stuff is compatible

Actually REX skyforce is compatible, I am using it. You have to get there latest installer. And most of the other stuff has dedicated installers or will simply work by changing the directory to V5.

Interesting. I think AIG AI manager isnt compatible…

That one I'm not sure about.

AIG AI Manager is compatible with V5.x ... check-in with Kai here.

I have AIG AI working quite happily in 5.2HF1 🙂

I have a BenQ monitor with a native 30Hz refresh rate. In a stationary left seat view the smoothness is without equal. No stutters as I’m only demanding around 60% of what the 1080Ti is capable of.

Panning though is jerky - the downside of only refreshing 30 times a second. But do we really spend our time panning around the cockpit? I don’t. I have ChasePlane views and that quickly switches views albeit with some jerkiness but it doesn’t bother me.

If you demand something your graphics card is unable to deliver - namely more frames than can be delivered - the result will still be a stuttery mess. The best compromise is to limit fps to 30 and with a 30Hz monitor that is achieved with no manipulation.

Hello all I think I found my solution… hopefully. What I did was customized a refresh rate on my monitor through Nvidia inspector. Since my sim never really drops below 45fps I chose 45Hz. Once I did this I kept my vsync enabled with triple buffering and unlimited frames in P3D. This all made a world of a difference! My sim is literally silky smooth as if I’m at 60fps. I can’t even tell the difference I swear! Airports that used to look kinda bad are now smooth as can be. I don’t know why my computer and sim love 45fps but that is my sweet spot. I still have some work to do though, I notice when I take off I see a little bit of the ground kinda tearing below me but only for a couple of seconds then once I get a little higher it goes away. I can probably tweak some things and get it just right. I have a i7-8700K @5ghz, RTX2070 8GB, and 32 gigs of RAM.

Strange but I have found that RTSS works well to limit to one half refresh rate whereas NCP 8.1.961.0 when set to 30 fps or one half refresh rate does nothing at all and I see fluctuations all over the place.

Yeah, I've seen others report NCP Max Frame Rate doesn't work while I've also seen some that say it does work (myself included with my own test cases).  Same with RTSS, for some the frame limit doesn't work, while for others it does work ... never really investigated.  Both RTSS and NCP Max Frame rate seem to work on my current Dev PC (Titan RTX + Samsung G9).

No, it's the second best.  The best compromise is to splurge and buy the best hardware possible - my q400 flights are much better at 50fps than 30 😉 (Maybe not at today's inflated prices though..)

Will a 3090 at a 3rd party Heathrow with 100+ Ai give you 60fps? Not without reducing those sliders I suspect. 😉

Anyway, each to their own.
