Basically, if OBS says I am at 60fps and the game I am streaming is getting 60fps, then it should be true 60fps yea? Also, is there any benefit to cranking up my bitrate if I have 25mb/s up?

Here is a link to a stream of mine for reference. http://www.twitch.tv/bhalubear/b/398811929

Here is a log of my OBS.

Yep, that's a 60fps VOD. A couple lagged frames here and there but nothing to worry about.

Thank for the reply. Just out of curiosity, if I were to set my Base resolution to 1920 x 1080, my actual monitor resolution, and downscale by 1.5x to 1280, 720, could I still get true 60 fps? Or no because my base resolution isn't the same as my output resolution?

Just an assumption but I would assume that FPS output doesn't really have much to do with resolution. If you have the capacity to push 1080p @ 60 then pushing 720p @ 60 seems like it would be entirely possible.

You should set your Base Resolution as your Desktop Resolution then use the Downscale to whatever quality you wish to choose. If you put 1280x720 in base, If you down scaled to that and set your base resolution you will not lose any quality. The quality will be the same as before...

While I agree that it doesn't make sense, check out these two vods because it seems that you can definitely tell a difference. The first vod I had my base set to 1920 x 1080 at 60fps and downscaled 1.5 x to 720p.

This second vod I had my base set to 1280 x 720 at 60fps and downscaled none to 720p.

I could be crazy but it looks like the first vod isn't in full 60fps while the second vod looks more fluid, despite only the base resolution setting being changed. Please take a look and tell me what you think or if I'm just crazy.

As I reported on the other thread, both of those videos are indeed 60fps. Resolution and downscale has absolutely nothing to do with frame rate.

Ok so then besides both videos being 60fps, is either one of higher quality? I know both are 720p but I have seen some streams with extremely good looking 720p and others with rather terrible 720p. On a related note, would you have any advice on how to get the highest quality 720p?

Using the downscale filter will look better, instead of setting your base resolution to 720 and fitting the game capture inside it.

@BhaluBear:

Are you asking your friend if he can visually tell the difference of "smooth" fps because that has a couple issues:
- Really REALLY subjective
- Based highly on the "in-between" as we'll call it.
- Not really ALL that exact.

@dodgepong:

Along the lines of the above, is there a way, natively, to have stream information appear similar to youtube right clicking on the video? I assume this is a site by site thing as it really depends on what information is being shown. IIRC twitch allowed you to view the info at one point but I don't remember how to get to it now.
