OBS render problem in Preview and Stream despite strong PC

Hello, I'm having a render problem recently that OBS stutters during games more or less when previewing and streaming.

My specs are:

Ryzen 5800x3D
RTX 4070
32GB DDR4 RAM

As said depending on the game it is more or less strong. Battlefield 2042 more and Baldurs Gate 3 less but definitely there in both. Tried nearly all basic suggestions I could find so far, at my wits end.

Log datas for one Battlefield and one Baldurs Gate 3 stream are attached.

Running the log for Battlefield 2042 through the OBS Analyzer you get a reasonable idea of some issues you need to address :


Warning 6.8% Rendering Lag
Your GPU is maxed out and OBS can't render scenes fast enough. Running a game without vertical sync or a frame rate limiter will frequently cause performance issues with OBS because your GPU will be maxed out. OBS requires a little GPU to render your scene.

Enable Vsync or set a reasonable frame rate limit that your GPU can handle without hitting 100% usage.

If that's not enough you may also need to turn down some of the video quality options in the game. If you are experiencing issues in general while using OBS, your GPU may be overloaded for the settings you are trying to use.

Please check our guide for ideas why this may be happening, and steps you can take to correct it: GPU Overload Issues.

Warning Capture Interference
Display and Game Capture Sources interfere with each other. Never put them in the same scene.

Warning Multiple Game Capture
Multiple Game Capture sources are usually not needed, and can sometimes interfere with each other. You can use the same Game Capture for all your games! If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.

Info Windows 10 22H2 (OK)
You are running Windows 10 22H2, which will be supported by Microsoft until October 2025.

Info Dynamic Bitrate
Dynamic Bitrate is enabled. Instead of dropping frames when network issues are detected, OBS will automatically reduce the stream quality to compensate. The bitrate will adjust back to normal once the connection becomes stable. In some (very specific) situations, Dynamic Bitrate can get stuck at a low bitrate. If this happens frequently, it is recommended to turn off Dynamic Bitrate in Settings -> Advanced -> Network.

Mh, so a bit confused about the GPU overload since task manager said nothing about that and I thought a 4070 should easily handle it. Will look into it though.

Also I guess I should start deleting Capture sources then, didn't know those would make such a big problem ^^'

OS Task Manager is high-level, it won't show a GPU bottlenecks that well (sometimes, if you really know what you are looking it, you can decipher such, or when certain aspects simply maxed out. But lots of internal bottlenecks possible, that require a finer grained monitoring tool than the OS Task Mgr

It is the mixing of the 2 types of Video Capture Sources in a single Scene that can cause the issue. You can research further on the exact scenarios that cause problems

Also, you don't want that many game capture to capture games, you only need one. If for a special need on one game you need to add another game capture, then create a new scene for it. It's the same for window capture. Display capture is the one you need to add on it's own separated scene and never mix with game and window capture.

Each one of this game captures are constantly trying to hook up to the specified game, causing issues.
As said before, you only need one for most cases scenarios. When you need a specific setting for an specific game, then add it on a separated scene.
