Question / Help Game capture gives black screen in everything but FTL

[Laivasse]

Hello

I've recently started experimenting with streaming and have only had any success through OBS with window capture. Any attempt to stream a game through game capture results in a black screen preview. The sole exception to this rule is FTL, which coincidentally is a game known not to work in window capture at all.

My system is:
2x GTX 570 in SLI (experimented with 2 different sets of drivers)
i5 2500k@4.3Ghz
Windows 7 64-bit
Single monitor setup

I've tried all I can think of, including running OBS as admin, trying OBS 32- and 64-bit, disabling various overlays such as Steam in-game overlay and Uplay overlay, turning off MSI Afterburner (with which I never used the overlay anyhow), trying different game window resolutions and disabling SLI. Nothing changed the end result.

Below is my latest log in which I attempted to run KOF13, Spelunky, FarCry 3 and FTL. Only FTL succeeded in game capture. The rest gave a black screen in game capture but worked in window capture.

As you can see the game capture log comes from FTL alone. When I attempt to game capture a game like KOF13, the game capture log merely looks like this:

This is still an issue. Only way I can use OBS is to stream from dxTory and capture that as a video source.

I discovered that game capture only stays black for direct3d games. A game like Euro Truck Sim 2 can be game captured successfully in OpenGL mode. Might that shed any light on what is causing this? DirectX 11 is already installed (by necessity, for games like FarCry 3).
