Stream LAG when recording on OBS

Hey everyone! I’m streaming PS5 games (Mostly Platinum hunting) with OBS 32.0.1, a 4K Elgato capture card, i7-9700K, RTX 3070 (8 GB), 32 GB RAM, and a 320 Mbps upload. Problem is, I get random FPS drops in my stream mostly only when I start recording using the NVENC Encoder. When I use the stream encoder there is no FPS drop or lag but the moment I switch to the NVENC encoder the lag starts. During my stream today during intensive sections the stream started to lag along with the recordings. I want to use the NVENC for higher quality recordings and the recordings through the stream encoder do not appear to be of suitable quality. To be honest I am new to this and I have been searching for answers but I dont know where exactly I need to start, I have attached my log files from OBS hoping someone may be able to help me.

Here are the results of your 2nd log from the log analyzer: [link]

Long story short, you're pushing your GPU too hard. Here's what you can do:

- Turn off Lookahead in the encoder settings. This will use the same GPU cores used for rendering.
- Try disabling the background removal filter. Those are known for being a little heavy to use.
- Make sure your games are using an FPS cap. Running with unlocked frame rates are a good way to have your GPU dedicate most of its power to rendering the game as fast as it can, thus starving OBS of GPU resources it needs to also render the video frame.
