How to quickly enable/disable NVFBC encoder for Nvidia cards on Windows

[loler_SK]

Hi there,
I use the below batch scripts (*.bat) files to quickly enable/disable NVFBC hardware encoder on HOST PC for compatible Nvidia cards. When NVFBC is disabled, Steam uses NVIFR. Try it if you want, works for me on Windows 7 64bit. So I no more need to uninstall/reinstall GeForce Experience to do this. Don't forget to restart Steam on HOST PC once the encoder is disabled/enabled. I expect that you need to have GeForce Experience installed in order to enable NVFBC.

I just did a clean install of nvidia drivers and I do not see NVIDIA Backend running. I opted out of Geforce Experience at install..

In that case you wouldnt see it listed if you are not using GFE

引用自 < Greg：

On the host PC open up the task manager and look for "Nvidia Backend". Pretty much every time hardware encoding randomly stops working ending this task will allow it to work again.

This is where in all my years of tech experience, without henryg telling me what was in the dump files, i have no idea whats happening here. Im now on 358.91 and the steam nov 10th build. For me nov 9th was unstable so was nov 10th but in nov 10th the issue took longer to occurr. NOTE it doesnt matter if the host creen is on or off. Id appreciate if henryg could give us an update on whats being done because im on the point of jacking in the in home streaming.

I'm a bit confused, I see a split decision wether I should be using GeForce to encode or not...What issue are you having with the latest nvidia drivers and the latest steam beta build??

I cannot get hardware encoding to work with Starbound, even with SLI off. Game has intermittent slowdowns, while streaming, that ruin the experience. Both fullscreen and widescreen result in a software encoder.

[Greg]

The task only seems to start (or at least only consumes CPU) during a stream, or after a stream if the encoder "crashed".

I'd give HenryG a bit of a break, he's a software developer. If he spent all of his time answering everyones complaints and grievances on this forum I think in-home streaming would be a year and a half behind. Usually these kind of issues are handled by a marketing or QA team and passed to the developers. The fact that there's even a direct line of communication here is outright amazing.

Oh yes henrys help is appreciated and my frustrations are not aimed at him in any way, id just like to understand why these issues are occuring. Im just frustrated because when IHS works it works well, but when it breaks your left scratching your head wondering why its not working. Im sure my setup is not unique either. Also given all the different hardware and software combinations out there it must be difficult to accomodate all setups.

Im trying my best here to narrow down the issue but cant. Whats frustarting is tonight im now using 358.91 nvidia drivers with nvfbc and all of a sudden i dont know if its the driver update or using steam://flushconfigs but its working again andd ive gone through and benchmarked 20 odd games and no crash at all. Yet i bet tomorrow it will start playing up again :P

Thanks for the scripts NVFBC works way better for me than NVIFR, on NVIFR I had several games which did not work and some which crashed steam entirely after a few minutes of gaming. NVFBC is rock solid and every game I throw at it works beautifully. I am just puzzled why Steam does not allow to chose an encoding method preferrable on a per game base, given that NVIFR as default encoding method for NVidia cards causes so many problems and switching it it to NVFBC is not obvious.

I have had more problems with NVFBC then NVIFR, it could just be my setup tho. I am using power line adapter today I will try to skip the powerline just to rule out my network as being the issue.

[werner]

Don´t underestimate the problems powerline can cause. I have an NVidia shield which I had hooked up to a powerline based Ethernet over Coax solution. The result was that NVidias speed and latency code went haiwire and I got 720p and blocky graphics while streaming on the Shield although the bridge had a netto speed of 200mbit/sec.
All went away once I moved to Cat6a based Ethernet. Powerline in any form is really more a pain than it is worth it.

Hello Guys,
i currently playing Divinity original sin (enhanced). I have the 30 mbps cap problem using NVFBC and i would try using NVIFR but i read that it is not working with this game?
There is a way to override this 30mbps cap?
I'm wired over 100 mbps, i tried changing both files on host and client setting 100 000 and even 1 000 000 bandwidth limit, but it is always stuttering on my lap top if i use a resolution over 720p (and this for any game).

My configs:

Host
i7 4770
gtx 970
16 Gb ram
hardware encoding\decoding and traffic priority enabled

Client
i7 720QM
AMD radeon 5600 Mobility
4 Gb ram
hardware encoding\decoding and traffic priority enabled

Thanks to all for any advice

Yes exactly, the script uses NvFBCEnable.exe from Nvidia GRID SDK.

No offence then, but love to try your idea and I will be downloading the .exe through more 'official' channels !! :)

I assume I will get it through Steam if I install the game?

[Greg]

You would have to download the Nvidia GRID SDK for Windows here -
https://developer.nvidia.com/grid-app-game-streaming

Inside the /bin folder is the NvFBCEnable.exe file. You have to create 3 shortcuts to this .exe (or if you're masochistic do it from the command prompt) with the -enable -disable and -checkstatus parameter on the respective shortcut. That would be identical to each of his 3 .bat files.

In the end the shortcuts should look something like this.

"C:/GRID_SDK/bin/NvFBCEnable.exe" -enable

"C:/GRID_SDK/bin/NvFBCEnable.exe" -disable

"C:/GRID_SDK/bin/NvFBCEnable.exe" -checkstatus

Is valid for gtx 560ti?

[Greg]

Nope, GTX650 or better is required for Nvidia hardware encoding.

[smokey_1]

Wow was hoping for a tool/hack to enable NvFBC just to try it out again, as i despise GFE then this is exactly what I need !!
Thank you :)

[ingsbr00]

Works on W10? Dont work for me... Have I download any thing?

[tarasis]

I have GeForce Experience installed, and have checked prefer NVFBC in the advanced host options (via Steam Link), but every game I've tried thus far has been saying its using NVENC H264

For instance

Big Picture Steam D3D10 NV12 + NVENV H264
D:OS EE uses Game Polled D3D11 NV12 + NVENC H264
Lego Marvel Game Polled D3D9 NV12 + NVENC H264
Just Cause 2 Game Threaded D3D10 NV12+ NCENC H264 (having the performance info on screen causes flickering of the info and lots of red spikes on the graph)
Metal Gear Solid: Ground Zero Game Polled D3D11 NV12 + NVENC H264
Xcom Enemy Unknown Game polled D3D9 NV12 + NVENC H264

Should I expect it to say NVFBC on the newest firmware update? (497) only got my SL today
