GPU is running at 100% when I stream/record with OBS and causing my PC to lag.

Hello,
PC:
GPU: amd RX 6750 XT OC
CPU: Ryzen 7 3800x
RAM: 32GB.
Normally, the graphics card is used at 3% (when I watch something on the browser), but when I start recording/streaming in OBS, it reaches 100% in the task manager, but when I go to AMD Adrenaline Software, it is at 30%, but the PC starts to lag. When playing games at high settings, the card rarely reaches 100%, but when recording where I have nothing running, it goes from 4% to 100%, previously when I had a gtx 1660 super OBS works well
These are the obs settings:
AMD HW H.264 (AVC),
CBR,
6000 kbps,
keyframe spacing 2s,
profile quality,
B-frame 2
Obs has the highest priority. I run it as an administrator and I turned on game mode and set Color Range to limited. I use Windows 11. I updated all drivers. The card also does not overheat, it has 53-57 degreesWhen I change the encoder to AMD HW H.265 (HEVC), the card reaches 45%, but this encoding option is not available for streaming.
Thank you in advance for your time <3
