In regards to the current issue with some Optimus equipped laptops not properly switching to the higher performance Nvidia devices for Diablo III, we'd like to collect some information. Please only respond to this thread with the info provided if you have the above the issue with the Nvidia device not being used in Diablo III.

Did you try running Diablo III from a command prompt or a shortcut with “-launch” specified?

If yes to the above, was it successful?

If "-launch" didn't work, please post the lines from your D3Debug.txt file between

Kuronishen,

Did you also try using the -usepageflip command line argument?

Thavus,

Do you have your Nvidia Control Panel set to the default settings or have a game profile created to force Diablo III.exe to always use the High Performance Nvidia GPU?

Thavus,

How did you implement the -launch option? Did you add it to the command line arguments in the Desktop app or edit the properties of a Diablo III desktop shortcut? We'd like you to try without using the Desktop app for now. If you don't currently have one, create a desktop shortcut to the Diablo III.exe file. Select Properties and then on the target line, after the last ", add -launch. make sure there's a space between the " and the -.

When done this way, the game should start up without invoking the Desktop App, using the older Diablo III launcher instead. We need to see if this allows you to use the Nvidia card or not with Windows 8.0.

Thavus,

Could you delete the game profile for Diablo III in the Nvidia Control panel?

If you right click the same desktop shortcut, is there an option to use the Nvidia device listed there and if so, have you selected it?

Thavus,

Ok, last question for now. What make and model laptop are you using?

Solist ,

We're mostly interested right now in seeing if people using Windows 8.0 are unable to get Diablo III to use the Nvidia device when not using the Desktop App (-launch enabled) along with having the game forcibly set to use it via the Nvidia Control Panel or by selecting that option when right clicking the desktop shortcut. For Windows 8.1, it appears to be a slightly different issue.

fantasbaby,

For Windows 7, which if any, of the possible workaround steps have you tried and are you currently using? Such as: Are you bypassing the Desktop app by starting the game from a shortcut pointing to the Diablo III.exe file in the game folder? Do you have the -launch tag on the Target line? Did you specify in the Nvidia Control Panel that Diablo III should always use the Nvidia device? Or are you using the selection to use it made available by right clicking on the desktop shortcut?

fantasbaby,

Do you have Nvidia's GeForce Experience app installed and in use? If so, could you uninstall it along with the current 337.88 drivers you have now and then reinstall an older release (link below) and see if it behaves the same? With the older release, use the Custom and Clean Install options, just installing the graphics and PhysX portions and nothing else.

fantasbaby,

Could I get you to screenshot the Desktop icon's properties screen for me or cut and paste what you have on the Target line? I need to be absolutely sure the -launch parameter is being used correctly.

"My Nvidia Control Panel has "High Performance Nvidia Processor" selected (greyed out - I can't make changes)."

This concerns me though as it would suggest a problem not related to the game at all but rather with the laptop's hardware or drivers not recognizing the Nvidia device properly.

Thavus,

There are a few areas we're looking at but our problem right now is all of our test laptops in-house aren't having any trouble in switching automatically, at least when using the -launch option to bypass the launcher for now. We're trying to narrow down what might be causing it for users but it's a difficult process when we can't reproduce it here.

I wanted to provide a quick update of where we currently stand on this issue.

Our engineers are working with both Nvidia and Razer right now, to obtain 800M series hardware that reproduces the problem in-house. We've a late model laptop from Razer currently that's able to switch properly when using the -launch option which is why we've been trying to get specifics from those of you it's not working for. Our other machines are a bit older and aren't having the problem at all. It's a tough issue to get a handle on when you can't reproduce it yourself so that's where we're concentrated right now.
