Virtua Tennis 4 and GT540m as Default? Optimus Technology.
I have bought my new Asus Notebook with GT540m graphic card included.
All is running cool but launcher of Virtua Tennis 4 doesn't see my GT540m, only Intel HD3000 graphic card.
I have changed in Nvidia Panel as default card for this game: Nvidia GeForce GT540m.
Another games runs on this card. Is it a mistake in launcher and in real I play on GeForce GT540 m not on HD3000?
I have the newest Nvidia Drivers installed.
Take a look at the launcher: http://www.imgbox.de/show/img/X6Fb0ZROkO.PNG
I am not familiar with Nvidia Optimus technology other than it switched to integrated when its not in use to save battery.
A few things I think would prevent Virtua Tennis from switching over. Make sure windows is set to high performance mode. A lot of times laptops will use little to no power for performance unless that option is enabled. (though sometimes it'll automatically enable it if the laptop is plugged in)
Another thing you can do is to see if this is a common issue and Nvidia has released a hotfix for it, try posting this issue on their forums to see if this is a common issue or search it on google.
Wish I could be more of help but I've never had any experience with using Nvidia's mobile GPUs since the 5600GT lol.
