HAWX2_DX11.exe needed to run as Administrator. Still strange, why only issues with intros when not running as Administrator?
"When I start H.A.W.X-2 /DX11 the intro screens/videos and sound are very slow and choppy. Tho, once I get into the game's configuration and play mode all's good and the game plays nice in DX11. But, no such issue, with the intros when the game starts in DX9. Is there a fix for the intros in DX11, or can I somehow delete the intros?"
And yes, my GTX590 does DX11 fine with all other DX11 games/modes/apps. At least H.A.W.X-2 benchmarks great in DX11 with tessellation in 1920x1200/ALL HIGH/4xAA - 213FPS!
Funny, I also have the DLC/Open Skies and it starts the intro videos and sounds just fine in DX11. I really dislike Steam's installs!
