T430s Nvidia GPU not being utilized

2013-04-11, 5:32 AM

I noticed that when looking at my nvidia gpu tray icon, it is almost never being used.

 

On a T410s I had a while back, I had the ability to choose to turn it on and off based on power schemes.  

1) Is there any value to keep my discrete GPU on and have it run all visual events?

2) If yes, how can I do this?

Only in BIOS if its similar to mine. Select the video as Discrete graphics and not Optimus. In optimus you have to cofigure it for each application you'd want it to use. Not single mode all on. Intel graphics is the default all on.

Having said that I doubt your graphics in Nvidia will be any faster than the Intel GPU and its used for external support of various panels. Thats another topic entirely. You likely not gain anything other than using less ram using the Nvidia since it has dedicated memory but will still use onboard ram as well.

I don't recommend having the discrete GPU run everything; it's overkill for running basic office applications. Things like browsers, Flash players, etc should all be sufficiently handled by the integrated graphics card.

Things like games and more demanding applications should definitely be running on the discrete graphics card.

I agree as you'll be generating much more heat with the Nvidia chipset and its ram running. Battery power affected as well but getting the heat managed on the smaller 430's is a challenge as it is. If you feel certain applications you use need to run on it you can configure them in the Nvidia Panel to run up loading. It kicks in automatically if you plug in a display on the Display Port (does on mine) so video viewing automatically is running Nvidia that way.

Optimus mode is certainly the best IMO

I guess the problem is that I do select programs and when I run them they don't show up.  

Not sure if I'm making a mistake?

I suppose it's possible that the program doesn't actually make any GPU related calls, so it's not triggering the NVIDIA GPU appreciably.

Try with something like a GPU-accelerated browser (IE9/10, Firefox, Chrome, etc.) to make sure the mechanics are working.

You should also be able to right-click and there should be a "run with graphics processor" option that will allow you to select the nVidia card.
