Title: Performance on secondary monitor
Post by: metamorphium on March 29, 2010, 12:27:53 PM

Hello,

I have a laptop with secondary monitor attached. I found out that when I run the game in window and drag it to the second monitor, the fps drops from stable 100fps to 14. Is it known / standard behavior or is it something with my laptop?

Thanks!

Yes, it's a standard DirectX behavior. DX sees two graphic adapters in your computer. When you start an application, it's assigned to one adapter. If you move the window to the other monitor, it's still rendered by the original adapter, and the resulting image is sent to the other adapter, which is slow.

However, when you start a game in WME, it should offer you the two adapters, one for each monitor. If you *start* the app on the second monitor, it should run in full speed.

Thank you. It's exactly as you wrote. Might be neat though if in the selection box was some kind of distinction, because now it has duplicated line of the video card. If there was (1) and (2), it could be more clear for end users. Not that it matters to me. :)

Thanks again  for explanation ::beer ::beer ::beer
