Bug Report FPS not going above 5

Hello,

I am having an issue since the most recent update. When I Preview or Stream, my FPS will start at ~30 and then immediately drop to 4-5 fps range. This is seen in the OBS program at the bottom right hand side where it tells me the FPS. Because of this my streaming is extremely choppy.

Here is my log file(It seems that a lot of frames are lagging):

**Note**
If I restart my computer, the first preview will run flawlessly at 30FPS, but when I stream it'll drop to 5.

I have reset my Options and nothing seems to fix this issue.

For some reason, CopyResource (copying the texture from your video card to send it to the encoder) is taking obscenely long. Does this happen even if you're not capturing a game?

Otherwise, try to limit your frame rate in the game you're capturing, or lowering the settings, to make sure that the video card has some processing power left over for rendering the frame and sending it to main system RAM for the encoder to deal with it.

I've personally used a GTX 260 with OBS without any major issues, so your video card shouldn't be the problem here, but a game maxing out your GPU definitely could.

It does it when looking at the Desktop, playing a game or anything.

I have used both Software Capture and Game Capture same problem.

I didn't use it for a month or so, and then I finally used it again and I get this problem.

I installed and used XSplit, that works fine but I like the lightweighted-ness of OBS, and the open source.

My Graphics drivers are up to date as well.

Ah, one more question. Is the stream itself actually choppy as well? A friend of mine, who has a GTX 480, has a problem similar to this. The preview window updates at some really low frame rate, possibly around four or five frames per second, but the stream looks fine. Have links to any recorded videos on Twitch?

Ah nope, no videos. Either you've got Twitch set to not record your broadcasts or you have them set to private. (A lot of people have their recordings set to private, so nothing weird in that case.)

Also damn, that sucks. I'm not quite sure what to suggest, bar a reinstall or borrowing a video card from someone and trying that one instead... maybe downgrading your drivers, actually? I know I use a pretty old set of drivers for my GTX 260, since the new ones aren't working so great for me with that card.

Meh, I'll just use XSplit for now I suppose. I noticed it work half the time and then just explode the other half.

Do you have the newest drivers installed for your GPU? Unlikely that this is the cause, but it's worth a try.
