Question / Help Perceived FPS loss when streaming

[Windows 98]

Hello,

No...This isn't a typical "HEY I NEED HELP STREAMING FPS LOSS LOL" thread. I've read through many of those in trying to find an answer to this.

Whenever I start streaming, I get an (expected) FPS drop. However, the game itself runs choppier than what it self-reports its FPS as.

For example, DayZ runs noticeably worse even though Afterburner reports its FPS as approx 60 FPS. Same with Team Fortress 2. When I begin streaming, it falls about 20 FPS in-game, but I'm still getting 150+ FPS in that game. Though the game reports as 150+ fps, it runs as though it's playing around 40-50 FPS.

I'm betting I've misconfigured something in OBS but I don't know what it could be. I know OBS is taxing on a computer, but I feel like this isn't necessarily a poor performance problem. CPU usage does jump a bit when I begin streaming, but it isn't ever 100%, so I don't think I'm hitting a glass ceiling anywhere.

Any ideas?

From what I'm seeing, you're testing for less than a minute at a time; it's recommended that you test each setting used for at least 5 minutes of live streaming (aka: not sitting at a splash screen, actual gameplay).

I'd personally recommend turning opencl off; it's caused weird problems with a few people in the past.

Another simple question; are you playing your games with VSync on? Definitely improves the quality (removing tearing) but it's possible that your monitors could not be playing nicely with it/interacting oddly, especially if you aren't using triple buffering. Likewise, some overlay programs (like Afterburner or Overwolf) have been shown to interact badly with OBS in the past.

I'd be tempted to shrug and just point at Windows 8 too, but that's just because I see it behaving oddly *constantly* at work, and being a general pain in the ass to fix. So can probably write that one off as personal bias. :) (Probably.)

I just happened to grab a random log that was fairly short. It makes no difference if I let it run. I had already tried disabling openCL.

I do sometimes use Afterburner, but it never really had any effect on FPS. I run vsync off in all of my games.
