hey ray.  There are tons online for you to peruse.  You probably wouldn't need a piece of equipment like this if you just are looking for 30FPS.  But gsync is more to increase smoothness yet allow a higher degree of FPS when available.  

I also wouldn't be able to offer anything relevant in terms of a comparison as I have p3d uninstalled.  

MSFS has supported frame generation for a long time, so there's no need to limit yourself to 30fps in that sim if you have a supported DX12 card.

Even if that's not the case, frame-generation mods like lossless scaling can essentially double performance without generating extra heat. This allows users of legacy sims and cards to achieve the fluidity that is missing at 30Hz.

I can appreciate that 30 is not enough for many and it depends very much on what and how you fly. Panning around a VC shows the limitations of 30 but I got use to it pretty quickly. For VR of course 30 is nowhere near enough.

I probably wouldn't benefit much with 50+ once airborne but I can see the attraction of a variable rate. I'm just surprised at how much those monitors cost. Something to chew on for the OP depending on his wallet I suppose.

Are you able to toggle that option off so a with / without comparison can be made to determine how many extra fps that feature provides?

I ask because at SimWings Heathrow with 150+ Ai and FSL Concorde I can just about achieve 30fps with my hardware with P3Dv5.3. Obviously you can't compare with Concorde but if you have a PMDG777 and use AIG Ai and a complex Heathrow what does your system deliver?

I've just checked the PD3200U and it still retails for the same price I paid 6 years ago.

Ray, Gsync does NOT increase fps in-and-of itself - not what it is designed to do. Gsync allows you to run at any fps without the stutters and tearing that happens when fps doesn't equal refresh rate. Gsync automatically varies refresh rate to match ANY fps up to the monitors max refresh. Example: you have a system capable of consistent 43 fps, but a monitor that can only be set to 60 Hz or 100 Hz - in that case the highest fps at 43 or below you could sync would be vsync 1/3 factor with 100 Hz refresh (33 fps). With Gsync, you just turn it on, lock at 43fps and Gsync matches with a refresh of 43 Hz, or depending on monitor possibly 86 Hz. - it's like automatic vsync for any fps - Gsync is the "smooth", not the fast - your cpu and gpu are the horsepower that provide the high (or not) fps. You have a blazing system that should run 4K at 40 - 60 fps everywhere, all the time, and a Gsync monitor would give you the flexibility to use that fps with the perfect smoothness you get vsynced at 30.

As micstatic said, if your system is not capable of more than 30 fps then buying a Gsync monitor is not going to do anything for you, but that's not the case for you - you are limited by an inflexible monitor with limited refresh options.

You spent a LOT of $$ to get the system you have - spend the additional $800 - $1000 to truly enjoy what it's capable of doing. You WON'T regret it, trust us!

BenQ monitors are great monitors, I know, I've used them in graphic arts for color accuracy. MSFS requires a different set of tools.

@somiller, very informative, thanks. I should start out by saying I don't have MSFS, just P3Dv5.3.

But my mind is open to acquiring it at some point in the future when I've tired of P3D v5. I don't plan on buying v6 and I suspect that will be the last LM produce using the original ESP code. I think they've gone as far as they can.

My BenQ is still performing admirably but I accept it is limited in what fps it can produce. Gsync opens up new possibilities and I'll certain research suitable monitors. Maybe BenQ will jump on that bandwagon.

 

Ray,

Gsync function applies equally to P3D. I bought my ASUS PG279Q for P3Dv4 and it was like magic for smoothness. If your monitor is serving you well at the moment that puts time on your side and should you find an attractive Gsync monitor you can make that move when it's right for you! Because of the obvious limits of my cpu I locked at 35 fps in P3D and let Gsync do it's thing to make it smooth. With MSFS I'm locked even lower and using the Lossless Scaling app to triple my locked rate - again, all synced by Gsync.

@somiller, thanks Steven. I wouldn’t want anything smaller than 32” and preferably 16:9.

Whilst a maximum refresh rate is shown no minimum is. Is 30Hz achievable with these Gsync displays?

Ray,

No minimum is shown because it is not relevant for Gsync. If you look at the info on Blur Busters they have a video demonstrating how true (hardware) Gsync can sync all the way down to 1 fps even though the monitor cannot refresh at 1 Hz. It works by using exact multiples of fps. Once again, I think it's important to point out that you would get no benefit from Gsync for 30 fps that you are not already getting. I think you said your monitor refresh is set at 30 Hz and I assume you use vsync - that already gives you perfect frame pacing and would NOT be improved by Gsync. The potential problem in your situation is that in cases where you cannot achieve 30 fps you will get stutters and tearing. With Gsync when you are not able to achieve your locked fps Gsync variably syncs instantly to what fps you have at any moment. Gsync is the flexibility to sync refresh to any fps. All monitors can be set to only certain frequencies, for example mine can be set at (Hz) 24, 60, 85, 100, 120, 144, but turning on Gsync makes the monitor variably sync to anything from 1 fps up to the refresh setting, which in my case is 144 Hz.

Steven, thanks for clarifying fps can be delivered down to single digits. My settings are realistic enough to prevent that happening.

Yes, VSync is enabled and monitor is set to 30Hz. I test with complex aircraft at Heathrow to ensure fps will not drop below 30 except very briefly on approach.

If I was to set 60Hz with a Gsync monitor the fps would still remain around 30 but once airborne would increase up to a maximum of 60. I wouldn’t expect to get much higher than that and it might not necessarily be a good thing as the GPU could be pushed too hard increasing temps.

Earlier you mentioned Gsync Ultimate. What is that and does your monitor have it? Model please.

My monitor is an ASUS PG279Q, 1440p and NO it doesn't have Ultimate as it was not available at the time this monitor was sold. ASUS has new models with Ultimate, including 4K monitor/s. I've forgotten what Ultimate brings to the table, but for P3D and MSFS I have not found a situation that stumps my regular hardware Gsync. I think the important thing is to make sure the monitor your select has real hardware Gsync, and is not a Gsync compatible monitor.

Just thought of something else earlier today, and you have confirmed it will work for you - LossLess Scaling frame generation! Change your monitor refresh to 60 but cap fps to 30 using NVCP or RivaTuner, install Lossless Scaling, turn off scaling and select 2X frame generation = 60 glorious fps at the resource cost of 30 fps - you will see virtually no additional CPU or GPU resource use, but you get 60fps. I know it sounds like magic, and seems to defy conservation of energy, but it does work and no Gsync required.

Stephen, this site shows all variants of Gsync.

I’ll have a think about LLSFG but notice P3D must be run in Windowed mode. 😟

@somiller, I took the plunge this morning and bought it. Less than 6GBP so worth a punt.

I’m still getting to grips with it and working out how best to configure my system. For my two light aircraft I can achieve 60fps without it. 60Hz and VSync set. So it only needs configuring for my Lear25, PMDG737 and Concorde.

It might be better to continue discussion on the topic in the P3D forum rather than hijack this one.

@somiller and @micstatic. After a couple of days trialling the Lossless Scaling app I'm delighted at the results.

I followed the advice in the video to set my BenQ to 60Hz and in RTSS set a frame rate limiter of 20. Then, using the app set x3 acceleration. The results are spectacular.

I can achieve 60fps at SimWings Heathrow with Ai at 100% and Scenery Complexity increased from Dense to Extremely Dense.

So 250 Ai injected in the 80nm bubble (previously limited to 160 to maintain 30fps)  which will include Gatwick, Stansted and Luton but the vast majority are at Heathrow.

That was with the PMDG737 too. I then tried FSL Concorde and that too could maintain 60 which is astonishing given its complexity.

Mouse operation is slightly inconvenient but hardly a big issue. All all this improvement for under 6GBP. Something for others to consider providing they use a single monitor.

Thanks for the tip!

Lossless Scaling works fine with multi-monitor setups as well. I currently have 4 monitors and use it all the time in X-Plane.
