Question / Help OBS studio preview screen very buggy lately.

[jds4578]

the OBS studio preview screen has become very buggy lately, especially trying to capture games like GTAV & Mafia 3, there are NO logs to this, and it is just an observation from the preview screen (even if there were logs, the only evidence would be, that OBS has successfully captured the games involved), and yes it is running with my logitech c920 webcam in the background.

After a certain amount of time the preview freezes, and nothing works in OBS studio ( version 0.16.2 latest, BTW), if you record locally, in mp4, and stop the recording (after it has frozen, that is) OBS studio completely crashes, and I have to shut it down, try to access the recording, and the recorded mp4 file is truncated, and the recording is completely lost.

this makes me, not want to stream these games on pc(besides the high CPU usage, etc.) and thank god i also have GTA 5 on XB1 & ps4, now i CAN successfully stream these games, through console & capture card instead. & mafia 3 i have ordered on ps4, so hopefully i can stream that through console & capture card (avermedia c985) thank god !

It sounds like you're experiencing a few distinct issues here: a OBS Studio preview lag, application freezes/hangs, and corrupt MP4 files.

First, don't record directly to MP4. As you've noticed, if something interrupts the recording, the file is lost. If you're using single-track audio, record to FLV. If you're using multi-track audio, use MKV or another container that supports multi-track audio. You can remux the recorded files to MP4 later if you need that format (OBS Studio > File > Remux Recordings).

Preview screen lag can be caused by many things. One of them is if you're running multiple monitors. If you have OBS Studio on a monitor different from your game or capture windows, and the monitors are running at different refresh rates or attached to different graphics adapters, then this can happen. Your log file would have indicated whether or not you have multiple monitors or graphics adapters and what was hooked up where, so you should always include a log file even you think it won't be useful.

If OBS Studio actually crashes (displays a crash dialog), then you would have crash logs that you should upload. They would be located at "%AppData%\obs-studio\crashes". If that is not happening, or you have no crash logs, then OBS Studio isn't actually crashing, but freezing or hanging. This is an important distinction for us.

Regardless of if it's an actual crash, you also need to provide the regular log files for issues like this so that we can analyze those and diagnose the issue.

Now, you say you both stream and record. Which are you doing when you experience these issues? Do you have logs for them so that we can examine them? If not, you'll need to get some new logs that show the issues and provide those.
