I am not streaming I have the OBS software set up just to record the desktop and save the movie as a mp4 which I later upload to either Twitch or YouTube.
The two games I am playing are via Steam, Call of Duty 2 and 3 which I am playing Coop.
I used this video for setup which uses the "Game Capture (Syphon)" but I am losing frames, this also takes away from playing quality while recording because its a bit erratic on my end. Here is the video which is from April 2016
https://www.youtube.com/watch?v=WTOCz8SorkY
Audio is fine the video footage is not fluid, when setting up Syphon I use the inject feature but the video is not smooth. Could I be missing something here, I tried doing the inject a few times thinking it was not working could I have corrupted either the COD2 or 3 or even the OBS I am wondering?
Thanks for your response. I am running the latest version of Macintosh OS and am saving the file as a mp4 then editing and uploading. I would light up like a Christmas Tree if I could get this working properly.
Thanks,
Kevin

stage_output_texture: min=0 ms, median=7.572 ms, max=55.633 ms, 99th percentile=17.689 ms

That's from your log. Basically your GPU is taking a long time to deliver a frame to OBS. That tells me that your GPU is most likely running near it's limit. Try turning down the settings in game. I would start with lowering the texture quality, and then the shader complexity.

Side note: If you're using a hackintosh, make sure that your GPU is installed in a 8x or 16x physical PCIe slot. (If you can boot into Windows try running GPU-Z to confirm, if you can't you'll have to Google for how to find that info on a Mac).

I am running a game from 2005 on a computer that is about a year and a half old which has no problems running games like Far Cry 4 so its hard to understand how there could be processor problems unless OBS has hefty requirements. I really do not think the computer is the problem but thanks a lot for your time and effort. This is a fairly powerful computer bought from Apple.

OBS does have hefty requirements.

Many of Apple's machines are very, very out of date at this point, so even if you bought it in the last 1-2 years, that doesn't necessary mean it is up to running games and OBS.

Your CPU is only an i5, not an i7, so it isn't even the best available on Macs several years old, and you're running at 1440p base resolution, which means OBS has to scale as well as compress and write to disk (in addition to the computer running the game).

c3r1c3 says the problem is your GPU, which is most likely the case. You'd probably benefit most from setting your monitor resolution to 1080p, if that is your target resolution for recording. That would take strain off the GPU while running the game.

You might also try setting your CPU preset up to superfast, from veryfast. This would help if the bottleneck is your CPU (but not if it is the GPU, as c3r1c3 has suggested. This will give you bigger files at the same quality but reduce load on your CPU.

Syphon usually works better than Display capture, but has problems with some games. Out of curiousity, did you try the display capture option?

All I did was reduce the size of the video being output, the videos are for YouTube and Twitch. OBS by default was generating huge screen sizes.
