VSYNC P3D V3

[SteveW 1,792]

My assumption is that one has NOT done ANY "tweaking" to their prepar3d.cfg.

 

FreeSync and G-Sync are different, don't use my table if your monitor implements any variant of those technologies.

 

Cheers, Rob.

 

 

 

 

I've had a few discussions with Beau H. (LM) regarding unlimited vs. limited and if I understand him correctly, unlimited has less code overhead and is the "desirable" settings IF one can sustain sufficient FPS to let Vsync manage the frame flow (this will produce the most consistent time frames).  

 

Limited is less desirable and is an additional software layer managing the flow (read slower).  Limited is intended to help when one can't sustain necessary FPS equal to or better than one's monitor refresh rate ... basically slowing the code down on the main render thread (doesn't impact other threads running as they all still need to be synchronized on the main thread)

 

By hey, whatever works for you ... use it.  

 

Cheers, Rob.

Seems to be correct. Why are some guys suggesting I am saying something you disagree with?

'Tweaking'? As if!!  lol  :smile:

 

It is a G-Sync monitor and not FreeSync.

 

Config Tweaks? (bear in mind that this is MY system).

It works on mine Rob but - as they say - YMMV.

[mikeymike 360]

I will try your suggestions with affinity mask also steve thanks,

 

sorry I am a little slow

 

so with 60htz refresh rate I should be at unlimited fps and vsync triple buffer off?

 

thanks

[markmco 22]

LM would be correct in stating that IF your system can render and deliver unlimited frames, then throttling back is counterproductive.

 

IF, however, variable (slower) frame rates occur under high workload/bottleneck situations, then the framerate limiter can be a helpful tool. That's the reason it is still a user option. The limiter induces less overhead/latency than the frame lowering situation itself.

 

As mentioned, we all run different systems (from BIOS on up) with various hardware and software that drastically effect performance and function.

 

It's an interesting topic, but there is no flat answer. Too many variables. This is reinforced by the shear number of options present to control video, both in and out of the sim.

 

For me and my hardware/software combination, 20 frames limited and no vsync just works. I'd never assert that this is the optimal solution for others ...or even myself since I am always experimenting.

 

To all my simming acquaintances here, I wish you a happy, healthy 2016! Let's get out there and fly!

Yes good idea to try those AM suggestions with 4 core HT=On.

 

What to go for on the Unlimited/Fixed issue will be down to personal preferences and system type and capability. With Unlimited it's up to you to try vsync and triple buffer comparisons.

 

 

 

What I find with a (say 60Hz) fixed refresh monitor and fixed fps, it makes sense to set a frame rate that coincides most closely with the monitor refresh rate or a whole fraction, i.e. 15, 20, 30, 60. Running the sim at a frame rate that does not coincide with the refresh rate means we are sending an image stream out of sync with the monitor in the first place. It may seem like a good idea to set 31 instead of 30, so that maybe we have one ready in hand, but unfortunately it's not timed like that. Incidentally, Rob's talking about the difference in computation overhead to switch into fixed fps pre rendered is no big deal. Buffers are switched with a simple pointer value change, and look ahead's only compute the next frame time ahead, 2/30th, 3/30ths, etc. But true it eats into your fps as I mentioned pretty clearly. If the frame buffer is used up it can take a little time to replenish, making it necessary to at least have double the unlimited fps showing before setting the fixed value.

 

Interesting to think of the way the sim pans out with setting fixed versus Unlimited, since the sim is computing a frame ahead each time the same value, and coincides with a monitor cycle more often, and so is more accurately displaying the actual view we should be seeing.

 

Sometimes Unlimited mode may not be appropriate when we do not get an fps consistently more than the monitor refresh rate. In this situation, we're hardly ever seeing the frame we should be in, because it's computed on the time it took to draw the last frame. With a scenario that runs less than the refresh rate of the monitor, take an outside view and pan in fixed mode. The view is computed based on a fixed time per angular velocity. Change to Unlimited and the panning view speeds up and slows down as the draw time decreases and increases, not good for panning, smooth turns, or TIR. Pans seem to stick to the sim time, the fixed fps settings produce an effect like the pan is not dependent on the time. Depending on the setup being used, this may not be an issue of the slightest significance.

[Driver170 42]

Steve, i'm getting frames upto 50 and back down to 30 in KSEA area, ASN, ORBX, 737 NGX. Should i still lock my frames to 60 or 30

[SteveW 1,792]

Hey Vernon, you're using multi-monitors of a different sizes and fixed view? In which case maybe stick to Unlimited, check it out with the triple buffer setting in case it helps prevent tearing, I'm not sure the vsync will make a difference there. In any case try out 20 and 30 fixed, I would try 20 on that. Remember that 30 requires 3/2 the throughput of 20.

[Driver170 42]

Hi steve no fixed views shown on them of P3D. Just for vpilot.

 

Will i use adaptive in NCP? I set 3 layers of CB storms in KSEA area and i'm managing 30-50 frames with 60fps locked in P3D

[Guest]

If "smooth" is the goal, the key indicators are:

 

1.  time frames (how long it takes to render a frame)

2.  the frequency and variance in time frames

 

The goal should be to get the lowest possible time frames with the least amount of variance ... AND situation not OR.  Meaning if you get some 5ms time frames but over 1 second but you have 15 frames that are at 80ms then that's not going to be smooth.  Also, if your getting 80ms time frames and you only get 1 frame at 81 ms (very low variance) but it's still not going to be smooth because 80ms time frame will be about 12.5 FPS.  Anything below about 15 FPS and control input starts to be a problem.

 

Cheers, Rob.

[SteveW 1,792]

Yes, good stuff Rob, hopefully Bert and Gerard will be getting clearer on this now?

 

 

...Remember also that when we have fps over 40 or so the time between frames is getting too small to worry about the variances anyway.

 

But I still think the problem when setting up the sim and causing confusion, is to expect too much from the fixed setting, and not understand the limitations of the Unlimited setting.

 

...When setting up the sim speed and making comparisons, the best advice I can offer is; turn off all AA, and all AI, and test with Unlimited. Any AA setting can set a low ceiling on performance, capping any setting we're trying to test and throwing the result off. Having any AI running will stutter the sim, period. So may as well accept that we'll have a degree of snatching if we have AI running around. There will usually be a little stall as the AI/ATC conversation starts up. Also remember that weather programs can be feeding weather, not only making some unavoidable little stalls (if we want the weather to change), but also as the time moves on for the "next test", make sure the sim time is the same, and that weather is historic and has no randoms.

You're going to have to try it out Vernon. But if using the fixed setting, whether 30 would be better than 60, either way the buffer will generally deplete when the going gets tough, so it's possible 60 or unlimited will be better.

 

There's no performance requirement when we're in the sky with 60+ fps all day. It's all about what happens when we're only getting 45.

[SteveW 1,792]

So I did some testing with AM 85 and 116 as steve suggested

 

I Have set it at 116 very smooth  also in  heavy weather 

 

Thanks steve

 

but those blurries in distance is bugging me LOD is set ultra

moderate settings

 

pmdg 777 ftx global fs global mesh ASN etc etc

 

looking out the window its is crisp I guess, thou I don't recall having these blurries in FSX

 

is it just p3d?

 

Thanks

[Guest]

FSX you can change LOD on up to 15 if you like (OOMs are very likely) via editing the FSX.cfg ... in P3D LOD is hard capped to 6.5, probably why you think distances are blurry ... got a screenshot and location?  As explained to me by LM the 6.5 hard cap is a result of how tessellation works.  But my guess is if we see any increase in LOD radius in P3D it most likely will come when it's a 64bit platform.

 

Cheers, Rob.
