Hello, yesterday i downloaded OBS for the first time and there is problem with FPS on stream. In-game FPS are good (60 all time) but stream there is just about 10-20 FPS on 700p quality and 5-10 on 1050p quality.

This FPS drop i have only with Game Capture plugin. With Dxtory there is about 20 stream fps boost but at cost of in-game fps (about 30).

Thank you for help.

Looks like your GPU is pretty old and is slowing down your Game Capture.

Try lowering your bit rate down to 3000 and raise the x264 preset to veryfast, and lower your frame rate to 30fps.

Also you could try running the game in Windowed Borderless mode and using Monitor capture with Aero disabled, or Window capture with Aero enabled instead of game capture.

still low fps...but when im using FFSplit+Dxtory i have smooth stream and smooth game (game and stream both same FPS about 40) so i don't know what differences are between dxtory and game capture...and i have 45-55 stream/ingame FPS with FFSplit+Dxtory and 30-35 stream/ingame FPS with OBS+Dxtory..

But I want to use OBS instead of FFSplit because FFSplit crashes too much..

Oh wait, I just noticed you are using both game capture and DxTory. You don't need to use DxTory anymore. Just use Game capture. OBS doesn't require the use of DxTory, since Game Capture works really well.

After you remove DxTory, can you post a new log with 30fps/3000 bit rate/veryfast preset?

I uninstalled Dxtory then i restarted game and OBS. There is new one:

It's having an insanely difficult time capturing your game...are you sure the game and OBS are running on the nVidia card?

What game are you capturing? Also, what happens when you reduce your resolution to 720p?

Something is causing too much stress on your cpu it looks like, Downscale to 720p then go to advanced>use multi threaded optimizations and set that to high. also set obs.exe to high from task manager. now if you already do, don't watch your stream while streaming. (check the vods after) or play it from another pc.

The slowdown is on the GPU, not the CPU. CopyResource is the part of the encoding that is taking the most time (98ms) which indicates a GPU performance problem.

LadaB, you're better off keeping Aero enabled and using Window capture and not using Game Capture at all. Or use DxTory and capture that output, I suppose. Just don't use OBS's game capture...your GPU is much too old for it.

Yeah man, having the same issue. I streamed last night and the FPS was being indecisive. For the first half or so, it was good, but then it was >5 FPS. I was streaming Overwatch at the time. I'm fetching the log now.
