So, recently I me and my friend have wanted to start up our own review/letsplay youtube channel. We want to review old games via emulator and new games via Steam, Origin, Battle.net, etc. Just to give you an idea we would probably be recording at first Overwatch, Terraria, The Culling possibly, and emulators like I said. I have no clue on what settings to use really because right now I am trying to record at crazy settings that look really good but don't work at all. I will be the one recording everything so I need to make sure the game runs smoothly and looks good for the recording.

My specs are as listed:
Nvidia GeForce GTX 960 2GB
Intel Core i5 4690k clocked at 3.5 ghz
8 GB of RAM
Windows 10 (I know its terrible but its what the people who built my computer made me get)

Please respond ASAP.

That works great, but I cant record at 60fps smoothly. Anyway you could figure out some settings that allow me to record 60fps?

Well, thats not true. I can record games like Stardew Valley and Terraria fine, but I really need to be able to record some more instensive games, like Overwatch and Rocket League.

Try using NVEnc instead. On a GTX960 you should be able to use HQ preset and set a high bitrate, like in the 20000 to 30000 kbps range, and a matching buffer size.

Failing that, post a log file from a five minute or longer attempt using your old settings and maybe we can tell you something to tweak.

NVEnc works so much better, but I'm still getting frame drops. Not as bad ones, but still noticable. First I tried 30000 kbps, that didnt work well. So I tried 25000, which worked better but still lagged, tried 20000, same story, tried 15000 and its still dipping occasionally to 49-56 fps and back up. I'm not sure what you mean by post a log file.

Is there something I'm screwing up in the settings? I will attach screenshots of all the important tabs for recording and you can tell me what I need to change.

No, a logfile. From the Help menu. It contains all your settings (so no need for screenshots) plus a lot more back-end information that we can use to diagnose the issue more accurately.

I still dislike NVENC as it's a band-aid method with poor quality. Even throwing a ton of bitrate at it isn't going to fix the problem if there's something underlying going wrong.
Would prefer to see a log from an x264 session following the HQ Local Recordings Guide settings.

https://gist.github.com/afcc519df783c1ba0d05a77143ce0dec That is the log that I have. It shows all the settings I have tried today and everything. As you can see farther down I capped it at 30 to see if it would drop frames still and it didn't at all but I really want 60fps. I was checking out the log for the last recording I did and it saw alot of 60fps which is great but it still dips in the recording and its pretty obvious that its OBS and not my game since Overwatch runs more than well on my computer.

The ones I just used on an 8 minute Overwatch gameplay are at the very bottom but you probably already knew that.

I don't see any attempts at NVEnc in the logs, so I can't evaluate why it still had "frame drops".

As for your latest x264 attempts, set your Scene Buffering Time to 700, not 400, 500, or 900.

Set the x264 preset (if you're not going to use NVEnc) to UltraFast, since SuperFast still isn't fast enough.

The line in the logs you want to look at is this:

11:51:18: Total frames encoded: 2080, total frames duplicated: 539 (25.91%)
Click to expand...

You want that to be less than 1%, otherwise its going to look bad. You're way way over that. That said, OBS duplicates more frames when just starting up, so to have a statistically valid log, you want to only look at encodes that are "long enough". I.e. about 5 minutes of high action content, at the least.

Things that won't affect the Duplicated Frames are: CRF (not to be confused with CFR), bitrate, buffer.

Things that will decrease duplicated frames: changing to presets that sound like they are faster... ultra fast will cause less duplicated frames than super fast, which will cause less duplicated frames than very fast, etc.

Also, encoding less pixels per second, by decreasing the screen size, or decreasing the framerate, will decrease duplicated frames. If UltraFast preset doesn't get you less than 1% duplicated frames, decrease the screen size. As a last resort, decrease the framerate (to 20 from 30).

https://gist.github.com/602aee9d8302c066c2f808ccc94fc909 That is my latest log from a gameplay I just recorded. Still not under 1 percent, but so much better than 25%. What do you mean decrease the screen size? I really don't to have to downgrade to 720p if thats what your saying. I will record another gameplay with NVEnc momentarilly, will reply with log after recording session. The video I recorded still lags btw, but it is so much better.

Duplicate frames are usually the result of an overloaded GPU. If you're running without vsync or an FPS limiter, or FPS is capped but your game settings are more than your GPU can handle, that's probably why performance is so poor.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH MY GOD. YOU SIR ARE A FREAKING LIFE SAVER. IT WORKS AMAZING NOW, NO LAG, AND BELOW 1% DUPED FRAMES. THANK YOU ALL SO MUCH FOR HELPING ME AND ESPECIALLY YOU SAPIENS. I will make sure to let you know if something happens, but thank you so much!
