Rather than post in the Tips section I thought I'd add this here until we've achieved consensus. I'm surprised how well it worked in 2.5, improving the smoothness on my rig, which was pretty stutter-free to begin with.

No reason it shouldn't work with V3 (or FSX for that matter)

 

The Nvidia driver set includes a number of elements by default. I'll use the current WHQL set (355.98) as the example

 

 

Software Modules • NView - version 146.78 • HD Audio Driver - version 1.3.34.3 • NVIDIA PhysX System Software - version 9.15.0428 • GeForce Experience - version 2.5.14.5 • CUDA - version 7.5

 

I've just disabled the HD audio driver in Device Manager and seemingly resolved a conflict with other drivers

 

I am sure most simmers just settle for the default installation and accept what gets installed. BUT if you don't have HD Audio controlled by the GPU (you use a CPU mounted sound chip or a separate sound card) then HD Audio drivers can actually conflict with your sound card drivers and cause stutters, but its very difficult to remove them as GeForce Experience just puts them back in automatically. 

 

So simply disable them at the driver level:

 

Device Manager - Sound, video and game controllers - `NVIDIA High Definition Audio` - right click `disable`, then repeat for `NVIDIA Virtual Audio Device`, if present.

 

Best part is, if you're uncertain whether the driver is used on your rig, or the sound dies on your PC, its seconds to turn it back on again as you're not uninstalling.

 

Try it and report back ! 

Good find.  Will try this tonight.

 

Every little helps...(as Tesco says)

I hate it when driver installation doesn't let you to disable installation of HD Audio Drivers, since I never use them. So, disabling them in Device Manager is the only way to go, but it's irritating when you see bunch of new added devices in Playback Devices window.

I stopped installing the HD Audio Driver a long time ago (when BF3 was released). To date, I only install the driver plus the PhysX software. NO HD Audio Driver, no (stupid) Geforce Experience. As long as you do not use your GPU to also deliver sound (via HDMI I guess), the HD audio driver is useless.

...? You CAN disable every part of the nVidia driver. I ONLY install the graphic driver and disable EVERYTHING else because I don't need and want it.

A real simmer NEVER settles for default installations and NEVER simply accepts what gets installed...  :wink:

Nice tip, will give it a go for sure.

While we are on the subject, what is the PhysX installation all about? Would you need that? I'm quite happy to go with the graphic driver installation alone if I don't need any other bits that get added. I have generally installed the default package and left it.

I must be fake then.  :smile:

From the nVidia site: "PhysX taps into the power of NVIDIA’s GeForce GTX GPUs to create incredible effects and scenes filled with dynamic destruction, particle based fluids, and life-like animation." Afaik P3D doesn't make us of this and since I don't play any other games, I don't install PhysX.

P.S. And you are as real as they get.  :wink:

Sounds like you'd need it for development maybe - In which case, its a no for me.

Err, thanks (I think)  :Whew:

Some time ago there was a post regarding NVidia services, Which there are five running and set as automatic, the comment was it may help in loading times if some of these services were disabled. not been able to find the topic so has any body tried this.

PhysX is used by many games or scientific software.

For example if you play with the great "Project Cars" simulator, I think all physic computations to predict car behaviour are based on PhysX API.

 

For sure it's useless for Fsx or P3d, but it's a developer choice.

 

One interest is to move from CPU to GPU some heavy computations again.

 

For example if you play with the great "Project Cars" simulator, I think all physic computations to predict car behaviour are based on PhysX API.

 

 

 

 

 

 

In which case why can PhysX not be used for ground/taxi physics.  

It could, even more than only on the ground. PhysX engine handle many computations where forces, acceleration, rotation moments, frictions ... are involved.

 

Again it's a development choice regarding technology availability at a project start. Also when ESP has been developed I think PhysX was not available, GPU's were not so powerful, and do you think Microsoft would have use NVidia tools for it? Commercial and politic considerations as well

 

And for now, ESP engine is a sealed box for LM I guess.
