I was on windows 10 before and it was smooth, but now its very laggy now that i upgraded to win11.
I was using win11 before i downgraded to win10 as well on the same hardware and its not this laggy

i dont have a gpu but my cpu is an `Amd a8-7650k with radeon R7`

heres the footage for the software x264:

Have a look at the result of the OBS Analyzer.

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.
obsproject.com obsproject.com

Currently, your CPU and GPU are overloaded and OBS cannot process video. See what you can do to address the issues identified.

There's more in that log but the only time I've ever seen this is when there is a Low Latency setting somewhere. I would disable anything LL.

Run OBS @ 30FPS if needed, that should eliminate the rendering lag. Any chance of rolling back to W10 or is that no longer possible?

See how 11 goes, hopefully I'm wrong but I suspect there's gonna be some pain no matter what. Going back to 10 might be less painful in the long run.

Here's the additional things I noticed in the log: It's enabled somewhere, not sure if it's something new in v30.1 as I'm not using it yet.
00:30:33.872: Enabling fixed audio buffering, total audio buffering is now 21 milliseconds

Running OBS @ 30FPS should allow you to record @ 1080p, use the AMD encoder & avoid x264.

Old Nvidia audio filters still in play.

Shouldn't have updated to W11. There's no drivers for it.

Pretty much all Windows Vista, 7, 8, 8.1, 10 drivers should work on Windows 11 just fine. But something seems wrong with the encoder looking at the logs. Your best bet is to use DDU (Display Driver Uninstaller) in safe mode to remove the drivers, then install the latest Windows 10 drivers from AMD's Website that @rockbottom has linked.

If that still doesn't do the trick, you could try this fix to update the AMD encoder (EDIT: this seems to have been integrated into OBS itself for a while)

i didnt work. i think its on obs's fault now since ive tried a couple of amd drivers that supports radeon r7. or maybe its because of windows. but then again i used win11 b4 but its not like this

it seems like an update broke the amd h.264 encoder from working smoothly since it overloads my igpu

Commenting to confirm like others the AMD HW H.264 (AVC) is not working smoothly either for me on 30.1.1. It was working fine on previous version of OBS using AMD HW H.264 (AVC) at 50000Kbps at 2560*1440 at 60FPS. Quality smooth videos . I thought maybe the OBS update needed the latest AMD drivers, so got those, still laggy/choppy, frames dropping, unusable videos.

I am running Windows 11 with AMD 24.3.1 drivers and OBS 30.1.1 and I just do offline game capture recordings.

Intel i9 10850k
AMD 6700XT GPU

I haven't tried CPU h.264 encoding but I did find a solution to smooth video recording at those bitrates and resolution and 60fps...If I use AMD HW H.265 (HEVC) instead, I get the quality smooth videos (using 50000Kbps at 2560*1440 at 60FPS) like I used to with the AMD H.264 encoder when it worked on previous version.

I want to say like others the OBS update broke just the AMD H.264. Hope it gets fixed. Thanks.

Yes i experienced the same but i changed the encoder from AMD HW H.264 (AVC) to x264 as solution or workaround as you wish.
The AVC should record as before because its better for some or most streaming and video sides.
I will follow this thread.
