Question / Help OBS Crashing With Left 4 Dead 2.

So I'll start off by saying I used to be able to stream L4D2 fine, and about two weeks ago (I'd like to say after updating to v0.638b but not 100% sure) I'm unable to. The issue is as follows using game capture in full screen:

1) If I launch the game, minimize to start the stream then tab back in the game is a black screen. You are able to hear everything and as far as I tell still move the mouse around. But obviously the black screen makes it impossible

2) Start the stream on the desktop then launch the game, which will cause it to fail to launch and immediately crash.

I've toyed with settings, different things and I was hoping someone could give me insight or maybe tell me how to go back to an older version to test if that is the issue. The main thing I'll say is I'll try anything except for using window mode with monitor capture because it makes the game far too dark for my purposes. Full screen game capture streaming needs to be working.

i7 4770
gtx 770

obs version v0.638b


Edit: Just realized I made the thread title OBS crashing with L4D2, that's a bit misleading as it crashes the game instead of OBS.

Are you using Razer Synapse? If so, close it and try again.
Are you using any antivirus software? If so, try adding the OBS installation directory to its ignore list.

Do other games also crash, or just L4D2?

I can't believe it was synapse never would have guessed that. Annoying because I use synapse for my DPI. Is there any workaround to have it open and stream?

Look in the Synapse software to see if there's any way to disable its in-game overlay/HUD functionality (there used to be, but I don't know if the option is still there in newer version of the software). Turn it off and see if the game still works.
