Bug Report Binding of Isaac: Rebirth Game Capture FPS Issue

[Sephious]

When I try to use Game Capture with the Binding of Isaac: Rebirth, the game gets really choppy. The reason this happens, is when OBS hooks into the game, it seems to change my refresh rate, or at least what the game thinks is my refresh rate.

Watching my FPS with my G13 gaming board and MSI Afterburner, after enabling Game Capture, my FPS is no longer limited to 60, but 120, and is usually in between there somewhere. Also, the API that MSI afterburner reports changes from OGL to D3D9 and D3D10 frequently with the game hooked, but stays on OGL without it hooked.

Using OBS game capture in conjunction with other hooking programs is asking for trouble.

 

[Sephious]

The only reason I fired up MSI Afterburner in the first place was to check if I could see any abnormalities in framerate because game capture is extremely choppy with Binding of Isaac: Rebirth. I don't normally have it running.

Plus, I've never had an issue with MSI Afterburner and Game Capture with any other game, as long as Stealth Mode is set to "on" in RTSS.

EDIT: Looking on the Steam forums, there are a lot of other people having the issue. Apparently one of the patches to the game may or may not have caused it, and that also may or may not be because the game's OpenGL version was upgraded/downgraded.
