Bug Report Low framerate of stream for some games

[AdamAK]

Hello everyone,
I've done a few initial tests with OBS, and am loving the software. I was able to stream games at a higher framerate and resolution, while taking a far smaller performance hit than XSplit. Sadly, one of the games I stream regularly doesn't work properly with OBS. The game Grand Theft Auto 3 runs perfectly while I'm streaming, but the framerate of the stream itself is awfully low; it's shows up on stream as if it were running at 15-20fps, when it should really be 60. Is there any particular reason why OBS would work great for games like L4D or Amnesia, but not capture something like GTA3 correctly?

I browsed through the forums for a moment before posting, so if this thread already exists, I unfortunately missed it. Let me know if you'd like a dxdiag log or anything.

 

[Lain]

nope, a dxdiag shouldn't be necessary, just a regular log file from the application would suffice.

Hey there AdamAK :D Mind sharing this thread with me? Same thing happens with Bionic Commando. Game runs smooth as I play it but OBS shows 15-20 fps on its status bar.

EDIT: I should of ended preview before posting the log, fixed. (Or closed the program, whatever I did to make it add more data to the end...)
Almost 50% lagged frames? That don't make any sense.. I'm sure the same is happening to his GTA3..post yer log Adam!

Hey,
Apologies for the late response. Something came up, and I wasn't able to do much with OBS for a bit.
Anyway, where can I find this log file? It doesn't seem to show up after a stream in the OBS folder, nor could I find it in My Documents.

I did a quick stream on a test account to show you what the main issue is here. Here's a highlight http://www.twitch.tv/poserak/c/1746460

Goto Settings / Open Log Folder from the menu.

 

[AdamAK]

Awesome, thanks. Here's my log for that quick test stream I highlighted in the previous post. I've tried various settings with streaming the game (mainly changing the resolution and encoding speed), but none of it made any difference. CPU usage while streaming is low.

How are you capturing GTA? Have you tried using game capture?

 

[AdamAK]

I was using the "Software Capture Source". Hadn't noticed that there were already several updates since the 11th, so I'll try getting a newer version of OBS and will try using game source instead. I'll post again once I've had the opportunity to test it.
