Question / Help Windows 8.1 and streaming? Window capture do not capture

So how do you actually stream now with OBS and Windows 8.1 I just got it couple days ago and I am loving it so much that it might be impossible for me to go back to Win7 (something really really important must happen for me to go back like slower performance with streaming on Win8 than on Win7).

I just plonked a preview stream (not actually, just a preview stream feature), opened Minecraft, put window capture as I usually do and... nope the game is freezed in the OBS window, so that is a little bit problematic. Why is that and how do you actually stream with this, so far I've seen Windows capture was:

1) Good on performance in games while streaming
2) It could automatically fit perfectly the size of window/game into OBS.

Awaiting reply's ^^
 
Window capture works fine on windows 8.1, same as previous versions. The issue is most likely with what specifically it is you're capturing -- minecraft cannot be captured via window capture because it's an opengl game, which bypasses the windows compositor. You must use monitor capture or game capture.

Oh? So that's the case? Will performance be the same with monitor capture compared to window capture? I know that game capture usually slows down the game. Btw. what changed so window capture in 7 works with every game but in 8 only with some? And basically all OpenGL games will not work with window capture and directX ones will work?

What is the performance of capture methods (Window, Monitor, Game) on Windows 8.1 compared to those capture methods in Windows 7?
 
Game capture shouldn't slow down the game, in fact game capture should be the top option. The only time it ever slows down the game is if you're on an older intel integrated chip or cross-adapter capturing. Could I see a log to verify if it's working properly?

I can't send you log because I am not using game capture anymore since very, very long time ago when it was slowing down game performance, and also I am on new OS right now (Windows 8.1 now, previously Windows 7) and after switching to windows 8.1 i deleted whole OBS setup and re-creating it from zero.
 
You did indeed explain why you were not using it, however I need you to use it once at least and generate a log from it so I can see if it's running properly. If possible, please do a quick preview session for just a minute with game capture, and give me the log file generated from that OBS session. I would be most grateful if you did.

I was runnig the preview for 10 minutes, couple minutes of this time was the game minimized to taskbar and for the rest i played it. Captured some Terraria.

The capture looks like it was working fine for that game, though the problem you were having was with minecraft wasn't it? Minecraft runs OpenGL, while it seems like terraria uses DirectX, which are different types of captures unfortunately.

I really do appreciate you making the logs for me though.

No, game capture was slowing every game, I just posted log from Terraria because that was the last game that I used with game capture back then and it slowed down the game as well.
 
That's actually very unusual, I wonder if it's related to your video card, I don't think I've really seen the 4xx model used that much let alone that 450. It feels very unusual that game capture would cause that, I wonder how many cores that GPU has, game capture scales up tremendously with more video card cores. Also the log looks pretty much totally fine, no stalls either on OBS' end. I wonder what's going on. Very strange.
 
Well I assume we will never know xD In near future when I'll be streaming I'll be testing game capture to see how it behaves compared to window and monitor capture.
