Stutter - Adaptive VSync could offer a solution

Featured Replies

Does this mean the adaptive V sync now works in v2.3? I remember seeing at LM's forum that they mentioned the adaptive V sync in Nividia driver is broken.

One should read the explanation at nVidia CP for the vSync parameter and it says it works only for OpenGL applications! P3D v2 isn't an OpenGL application, right?

probably... I just remembered that adapative Vsync worked well in FSX DX10 once set through Nvidia Inspector.

So do some see a placebo effect then if it cannot work through the NV control panel ?

Hi Spirit,

 

I think you should have qualified this statement by stating that this applies to Triple buffering with VSync enabled. Adaptive VSync works just fine when enabled in NVIDIA Control Panel under Global Settings. Just remember not to enable VSync in P3D and forget Triple Buffering.

No, no and no.

Adaptive Vsync only works in exclusive full screen mode and P3D 2.x not have this mode, but a false full screen.

Try to check the FPS with ALT + Z, with EVGA X or with other external software and you'll see that go well beyond the refresh rate of the monitor.

Hi Mike,

I guess you didn't read the explanation for vSync in nVidia CP very well.

 

Nowhere is written that this applies to Triple Buffer it only says that Triple Buffer is working together with vSync. It says very clear that vSync works for OpenGL and not for Direct3D. Maybe you are still running Windows XP then you're right it works but this doesn't work for P3D v2. :lol:

 

Anyway, it's up to you what you believe. If you think it works for you then it's ok and be happy but you should avoid to convince others to follow your believes.

Hi Spirit,

 

Please spare us your somewhat unexpected and unnecessarily patronising tone, it does you no credit. Are you now inferring that those of us, including yourself ( http://forum.avsim.net/topic/443715-stutter-adaptive-vsync-could-offer-a-solution/?p=3004271 ), have been deluded while witnessing improved P3D performance with Adaptive VSync enabled under Global Settings in NVIDIA Control Panel? What's more, Adaptive VSync appears to be working under a windowed full screen since P3D does not currently offer a true native full screen option. These observations were made while using the 337.88 drivers.

 

I am assuming that somewhere along the way we may have misunderstood each other while reading our respective recent posts in this thread.

 

All I am suggesting is that you ignore the VSync and Triple buffer option settings in P3D while using Adaptive VSync in NCP as the latter will likely override or conflict. Also, you want VSync to switch off while your frame rates are < your monitor's refresh rate (assuming 60hz for the majority of monitors currently in use).

 

Regards,

Mike

Untrue. The Nvidia Vsync options apply to both DirectX and OpenGL games/software.

Not with nVidia CP! You've any Proof for this?

Well, I was wrong too! But telling something wrong 1000 times doesn't make it right.

Spirit

hmm, I have Vsync on and triple buffering inside P3D. I also have deleted the P3D profile that come with the newest drivers

 

What benefits do i get if i disable those ?

@all

Just did some tests about vSync/Triple Buffers.

Always the same short flight with same day/time, weather, aircraft, scenery, same settings except vSync/Triple Buffers in nVidia CP. In P3D v2 vSync/Triple Buffers OFF. Average FPS from FSUIPC4 log. No setting for vSync/Triple Buffers with nVidia Inspector.

  1. nVidia CP vSync OFF / Triple Buffers OFF    D3DOverrider inactive      44 FPS
  2. nVidia CP vSync ON  / Triple Buffers ON       D3DOverrider inactive      44 FPS
  3. nVidia CP vSync OFF / Triple Buffers OFF    D3DOverrider inactive       44 FPS
  4. nVidia CP vSync OFF / Triple Buffers OFF    D3DOverrider active         37 FPS     

I think that this is a kind of proof that vSync for P3D v2 is NOT working if set in nVidia Control Panel.

Spirit

Untrue. The Nvidia Vsync options apply to both DirectX and OpenGL games/software.

 

I have always believed the nV options in this case are for OGL only, and not D3D... Triple Buffering can be offered by developers, as an option in their titles, and I think there are tools to force it on.

 

I've never tested these facts (EDIT: looks like Spirit just has :P ) but have seen it quoted many times.

The adaptive vSync works well on my rig. Just a little improvement from an already very good and smooth P3D v2. It looks like that there is some load moved from the CPU to the GPU.

Good finding

You need not to repeat this endless because I already said that I was wrong and I know now better. Is this fine for you?

 

You also can read that I talked at this time about a little improvement and obviously it wasn't really an improvement because my rig and P3D v2 was already running smooth.

 

Look at my findings now and you should eventually accept what's real.
