Surface Pro 7+ Recommended setting to avoid fps drops

I have the i7 32gigs ~1 tera SSD "Microsoft Surface Pro 7+"

I'm experiencing severe fps drops in OBS when replay buffer is active . I'm currently replay-buffering-only at a resolution of 1280x843.

1. Run OBS as Admin. Right click on the shortcut, properties, advanced, check box, ok, apply, ok.
2. OBS Settings, Audio, General, Set Sample Rate to 48 kHz. Do the same for your Elgato HD 60 S+.
3. Create a new scene collection with 1 scene with 1 source (whatever your main content is), restart OBS and post a recording log of that.

i don't know what "shortcut are you talking about and I don't know how to change the audio sample rate to 48 khz on the elgato specifically.

here's my latest log. The only thing that has been changed is the general audio sample rate ( I changed it to 48 khz, like you said).

Aaahm. Crazy values!

2560x720 doesn't make any sense. Its a screen ratio of 3,56:1 you should have seen this.

Go for 1920x1080 in
- Base resolution
- Output resolution

- Disable rescaling in the encoder settings

- If you just record, switch to CRF method in the encoder and go for target values between 23 and 20. Don't go for CBR with crazy values like 25.000 or 50.000. You don't have usable GPU.

If all that doesn't help, switch the output resolution to 1280x720.

And: qhobbes asked you how you start obs. That should help you find your shortcut in your windows system (possibly on desktop?). There you could have a mouse right-click to and choose "run as administrator". You may learn alot about obs and windows. =D

2560×720 does make sense because i'm capturing 2 viedo feed's - facecam and console feed - side by side , then seperate them in premiere for future use.

How do you open OBS?

Since your Elgato is outputting at 59.94 change your OBS FPS from 30 to 29.97.

Using Windows Update, update to the newest available version of Windows 10. After you have updated Windows, open the Task Manager, go to Performance and check the GPU to make sure nothing else is using it. It should look like:

Once you have confirmed nothing else is using the GPU, open OBS (don't record/replay buffer yet) and then check GPU again. It should look like:

If something else is using the GPU, go to Processes in Task Manager and check the GPU tab.

1. Did you update Windows 10 to the newest available version?
2. Close BlueStacks Player, Discord, Google Chrome and Spotify.
3. What is the second OBS Studio process? > OBS Studio (2)
4. Create a new scene collection with 1 scene with 1 Text (GDI+) source that shows TEST. Restart OBS. Try Replay Buffer with that scene.

I admit I had not. Now I have and OBS gpu usuage is much better at teens%, not 95%-99%.
I'll update if I encounter more issues.

By the way, what sould be the bitrate for a 2560×720 video?

For recording, you should use CQP/CRF (or whatever QuickSync calls it) where you pick a quality level instead of bitrate (CBR).
