SLI Load Balancing Graph not working?

[Orion7486]

Hi all,
I'm using 2.5.3 Beta2. The Load Graph isn't appearing on either Rise of Flight or MS FSX. Now, it's possible that RoF doesn't use SLI, but I would imagine that FSX would.
I believe that I followed the steps correctly in the documentation pages.
Since both are marked as predefined, I even clicked on the override predefined option.
Anytihing ideas?
Thanks for any reply.

Where are you enabling it, nhancer or nvidia control panel?
You need to enable via nvidia's control panel.
I will try with nhancer right now though.

Seems that it does not work when you enable it from nhancer, at least not on 191.07
From nvidia control panel it works.

Yes, they changed it ... grrr.

Violator, I enabled SLI thru the nvidia control panel. Then within nHancer I tried to put in the Load graph.

Grestorn, what did they change? The graph capability itself?

They probably changed the name string to the graph.

Yes, they changed it ... grrr.They did, and there is also a PhysX graph now (in the 191.xx drivers, at least).

It seems that I can't fix that so easily. It's no longer a value in the registry, it just seems to be a flag in the driver's runtime.

Maybe if nVidia gives me access to the non-public part of the nvapi.dll I can include it again, until then the feature will be taken out of nHancer.

Ah, I thought you meant enable SLI thru nvidia's control panel. I hadn't seen the setting for visual indicator within the control panel. I now have it enabled and the graph is showing in both ROF and MS FSX.
ROF shows the graph almost completely filled. In FSX, only about the middle third of the graph is filled.
Thanks much.

Hmm but the NV CPL will still need to write the flag to disk when you enable it.
So if it isn't added to the registry it must be added into some file.
To keep the flag turned on after Windows got shut down/restarted.

Darn, cant see which files nvcplui.exe makes a backup to when I close it.

[Grestorn]

Ok, I figured out that the flag is still the same nHancer used to set. But it's not enough to set the flag in the registry, the driver has to be triggered somehow in addition.

If you change the flag and reboot your system, the change does work.

I don't think I can do anything about that though... :( not without the non-public documentation of the nvapi.dll.

Thanks for searching that out.

Hi folks!

I can get the SLI load bars (SFR and AFR) / SLI AA info on my system but only when nVidia System Monitor is not running (I use the latter to monitor my core speeds, just to see how they handle throttling in various situations). I'm using 191.03 and 2.5.7 on a GTX 295 with a variety of applications but especially nVidia's own demos (basically a hacker at heart and I wanted to see how many of them I could make run and with what setting, how much performance, etc, etc).
