Nvidia Control Panel and P3D v4

[Ursli80 2]

Hello everybody,

You are just super great here and many thanks for your support. This is unfortunately Google Translator. This has me translated it so that SteveW this multilingual writes.

I am concerned with the text of the SteveW on page one where he has himself quoted and he describes the procedure with Nvidia Inspector.

Also it would me with the AF entry wonder where exactly this must be placed and how I get to the number that I have to enter after the =

I would like to sincerely apologize for this. But as already mentioned, such things never had to start with the P4D V3 and always had over 20 FPS with my 3 projector setting and Warpalizer Warp Software.

 

Thank you for all your help.

 

Best regards from Switzerland

Urs

Hi Steve.

Thanks for your help.

Well I tried the 116 AM in FSX (01,11,01,00)..... and, as there are no vert sync settings in FSX itself, I set Nvidia Inspector to limit fps to 60, and Force On vert sync.

In the sim, I also set FPS limit to 61.... this seemed to prevent it running at 59 all the time - wierd huh ?

BUT, FSX is actually running better than ever now. Running on 4 (lp) cores to itself, it often hits 100% on all 4 for short periods, but my addons like AS16, run on the first 2 empty cores... along with the OS presumably.

The Biggest difference isn't so much FPS, but lack of blurries, especially after switching views. I actually had to check my sharpness settings hadn't changed.

 

Ironically, having finally got FSX running as well as I probably ever will, I am now moving over to P3D v4. Clearly I am a glutton for punishment !

 

So, having now read all your 4,768 posts - well many of them (!) - am I correct in the following basic assertion:

P3D v4 is different to P3D v4 in a number of ways. One such difference is that it only runs in pseudo-full screen...

...SO Vert Sync should only be set in the sim, using nVidia inspector, only for limiting the framerate (experiment for greater stability), and AA if required ?

(This is clearly different to the case in FSX.)

Secondly, the ideal settings in P3D v4, is to use Unlimited FPS, with Vert Sync set to ON.

Thirdly, Triple Buffering and FPS limit may be used via the P3D settings only, and only IF it improves stability/smoothness. The FPS limit may be used instead of, or in addition to, the limit used in nVidia Inspector.

Fourth, it may improve stability, if the FPS set above, is actually 0.5 or 1.0 FPS lower than the amount you actually want.

 

I hope this summary is accurate, or I will need to read those 4000 odd posts, again !

Hi there, yes, seems like you got the hang of things - good luck with P3D.

Just to expand on this. Vertical Sync with FSX is controlled via NVidia Inspector - this controls screen tearing or in other words controls when the monitor displays the new frame buffer, complete or not. If incomplete the view might show two halves one a step behind giving the impression of a tear in the middle of the screen (or someway down).

The Vertical Sync with P3D is under control of the desktop and hard to fiddle with. In the P3D display settings the "VSync" setting does not control when the monitor displays the new frame buffer. P3D will only display each frame when complete.

What P3D VSync=On (+Unlimited on the fps slider) does is tell the sim to train the GPU output to the timing of the monitor refresh frequency, whether it can accomplish it or not, it is not a limit. This means if the GPU/CPU have the reserves, you will still see the fps wobble around the refresh frequency because it's being offset by the time it takes to build each new frame, as the scene changes so does the time to build the frame.

With Unlimited set each frame is computed ahead for the average time period per recent sequence of frames. This means that unless the sim is very stable each frame displays at a slightly "wrong" time because there's no guarantee that the frame will be displayed at the right time for the computations made for it.

With locked fps on the slider, the memory reserved for the buffer is used for the look-ahead frames. Each frame is computed for the exact time period between frames and is shown precisely at the right time for the objects and terrain positons computed in the sim. The sim is slightly more accurate with locked fps than with VSync=On+Unlimited. Locked takes more reserves, runs the sim with accuracy (if the machine can handle it) but introduces a tiny delay in response to the controls, not enough to notice.

OK, so it is EITHER.....

 

1. Vert Syn ON, in sim with FPS set to unlimited

OR

2. FPS set to 60 or 30, with no Vert Sync ?

And, what about triple buffering ?

 

Also, is there any role for nVidia Inspector in P3D v4 regarding using the FPS limit, or is it just a case of trying both ?

I was really hoping that I could basically forget nVidia Inspector with P3D and just do stuff in the sim settings......

........(with the possible exception of SGSS AA, which I am hopelessly addicted to, as shimmers and jaggies make me have VERY violent thoughts - and as such, has just cost me 600 quid for a GTX 1080 !)

 

P.S should mention that I run a 60hz monitor..... no adjustment.

Unlimited : VSync + TB 

Locked : no Vsync , no TB

Hi.

So just in sim.... no need to touch nvidia inspector ?

I use NVI for one thing only as the main Control-panel in Nvidia doesnt have it with my current drivers. 

(Performance mode for single Display)

Hi guys !

And how would you set P3D +- NVI with a GSYNC screen ?

Now I've a lot of tearing in full screen but very less in windowed mode. 

I tried a lot of set but nothing is better.

Help would be  very apreciate =)

G-Sync only works above 30FPS. As I do not reach this limit with my settings on heavy airports, I completely turned off G-Sync for P3D via nVidia Inspector. What I have globally activated is the fast sync option. But honestly, I do not know what this actually does, but as long as I see no negative impact, I keep it like that.

Fast sync only works above your monitor's refresh.

I also use G-Sync. Why do you switch it off? As you noticed, it kicks in if you are above 30 fps, and then it does a very nice job up to your monitor refresh rate (in my case 100 Hz). In less heavy situations I am sure that you get also more than 30 fps. And-G-Sync does not harm, it is a nice feature , so I would leave it on - and then just forget about it.

[AnkH 2,266]

Sorry, forgot to mention the reason. I configured my sim as such as that 30FPS is the sweet spot. Means: my settings are configured to provide 30FPS in most cases. In heavy load situations however, I am below, sometimes as low as 20FPS, in "easy" situations I would be far above, I limited my FPS to 36 (1/4 of my 144Hz monitor). Now, with my monitor, sadly the switch from those 144Hz to 30+Hz is clearly visible (a faint flickering). Instead of having a flickering display when the FPS vary between 25 and 35, I turned G-Sync off for P3D. That's all about it ;-)

I tried steve's settings but it seems like locking it at 30 inside the sim gives less stutters than locking through NVI and using unlimited in the sim.

Monitor is running at 60hz.

[SteveW 1,792]

If you look back through the thread you'll see I mention locking is better in P3D v4 than the older products. Also I mention that Unlimited+VSync is wobbly by design and that locking is superior - if you have the hardware.
