post #1 of 8
Thread Starter 
is it possible to disable SLI for games that are nt too demanding within the NV Control Panel??

definitely yes. just to go nv control panel, under sli option, select disable SLI.
although if it was me, i'd leave sli on and enable 64x AA >biggrin.gif

I don't mean to hijack the thread, but can you do the opposite of that? i.e. have SLi disabled by default, then have it enabled within games?

This is essentially how SLI works by default. It only enables in 3D apps.

That make sense.

What about switching modes, i.e. "Activate All Displays" in Windows, then when a game launches "Maximize 3D Performance" or "Span Displays with Surround".

I'm pretty sure it is not possible, but I would love to be proved wrong.

The thing is if you disable SLI while on the regular Windows desktop, you won't be able to utilize Surround in 2D.

Nvidia has yet to implement profiles like how AMD has with their drivers. eek.gif In my experience, it's a pain to constantly switch back and forth between Surround and Activating All Displays. When I had my setup running, I just kept it in Surround mode and just got used to it over time.

We really need to band together to get Nvidia to give us basic functionality that AMD users have been enjoying since the introduction of Eyefinity! band.gif

This is what I do, except in games like BFBC2 where no amount of extra eye candy will keep it below 100 fps, then I force vsync and enable triple buffering. Which makes both gpus max out around 50% load, probably not the best power saving feature ever, but its better than seeing it scream along at 200 fps in some areas.

Activate all displays makes then all a 3 different monitors, and you won't get the streched desktop like surround does. This will have effect on opening windows, making them full screen and so on.

Surround only works in SLI. You can't have surround without SLI.

Tho I don't really understand the reason why to disable SLI.
Let the drivers work on it, and they will find the best way to work.
You can just set the settings to be give better power/performance over just full performance all the time.

If you are running one GPU at 80%, or two GPUs at 40%, it will pretty much pull the same watt from the wall.
When the card runs at full core speed, it doesn't mean it pulls a full watt from the wall. It takes just what it needs depends on how much you utilize it.
The full watt usage is only attained when you push the system to full, aka furmark or the sort.

My system takes about 1000W while playing a high requirment game.
It takes about 350-400W to idle, and 550W for 2D.
On full blast when benchmarking the system to hell, it takes closer to 1650W.
This has been tested from the wall, so actuall pull of the system is a bit lower as PSUs aren't 1:1.

Nvidia and AMD both have very good power options in their GPUs, so disabling SLI just to save power, well, its just a waste of time to really worry about it.
