Question / Help Choppy recording at 1440p that worked fine previously

Hello all,

I apologize in advance, because I've been researching and I know this issue has been posted 10,000 times, but alot of the posts i'm finding in my research are from 2 or more years ago with OLD versions of OBS.
This post is concerning the NEWEST version of OBS.

I just recently picked up the streaming/recording hobby, and I really enjoy it, but I will pre-face by saying I'm certainly in need of more knowledge.
I've watched videos, tutorials, and read OBS postings about the "optimal" settings, but it seems I always end up running into frustrations!!

The Problem: My main frustrations have been with Doom 4. I tried streaming it first, but that was a waste of time and it was horrible and choppy because my upload is only about 5 Mbps. So I decided to do local recordings, and then upload to my YouTube channel.

Several days ago, I did my first recording. I set the game settings to 1440p. After toying with OBS for a while b/c it REFUSED to do a full screen gaming capture, I finally found that I could do a Windowed borderless setting, and tell OBS to capture the specific Doom window. However, sometimes even this fails, and the preview is frozen. Sometimes I have to set it to "match executable name" and sometimes "Match Window name" (or something like that, I can't remember what it says)
BOTH of these options have worked, but neither of them work consistently every time. It seems just freakin random.

Anyways, I did about 1.5 hours of recording at 1440p, and the video quality turned out fantastic! It's smooth, not choppy, no audio delays or anything, looks great.
Well, I tried to do a 1440p recording last night, real quick this time, it was only about 15 minutes (I was just beating the final battle of the Kadinger Sanctum realm, so I could add that to my previous Hell recordings). When I reviewed the recording, it was total and complete CRAP. Literally none of my settings have changed for recording. Everything should be exactly as it was when I recorded that 1.5 hour session! I double checked my settings to confirm this.

Again, I'm sorry, and I know this question has been hammered into the ground, but i'm just so frustrated, and I've done hours of research and video watching, and most of the info I'm finding is for OLD OBS versions, and the settings don't even look the same anymore!

I've seen alot of people upload logs. Where do I get those? I'm at work right now so I can't upload them, but I will as soon as I get home.

Side Questions: (cuz i'm still new to this)
1. Should I set my bitrate much much higher when doing recording as opposed to streaming? I currently have it set to 2400 I believe based on my upload speed, but I've seen people suggest 30,000 for local recordings? Could this be part of the issue?
2. If my native (base) resolution on my monitor is 2048x1152, do I need to tell OBS to "scale" in the Video tab? Or just set it to the same resolution? Does this affect the game negatively since it's set to 1440p??
3. Should I try telling my game video source to scale to 1080p, and see if it's still choppy?
4. What other troubleshooting / settings should I tweak to try and isolate the issue?

Thank you I definitely will upload a log as soon as I'm home. As mentioned in the OP, I am currently at work so I don't have access to my gaming computer.
I do remember I am currently using simple mode, but honestly I don't know what the presets even were originally b/c I've done so much tweaking and messing around to try and make this work!

Now keep in mind, I don't HAVE to record at 1440p, I'm totally fine with 1080p 60fps. It's just irritating because the last recording I did at 1440p worked great, but the one last night looked like crap, and literally nothing has changed in my settings!

Well, if you're using the presets in simple mode, there's not really much you can change.

Grab a log per that thread and we can go from there.

Are you talking about in the "Output" tab? Or in the Video tab? Sorry I don't have the software in front of me right now, so it's hard to remember.

Will do.
I will do some test recordings tonight and then upload the log files. Where do I find the necessary log files?
Also, do I need to be doing any downscaling? My monitor native resolution is 2048x1152 (weird i know, it's an old monitor, about 8 years), but it is a very nice Dell monitor SP2309 if i remember correctly.
Anyways, should i tell OBS to downscale the Game source to 1920x1080, or what is best practice?

For reference, this is my build:

PSU: Corsair RM850x
MoBo: MSI Z97 Gaming 5
RAM: Kingston HyperX FURY 16GB (2x8GB) 1866MHz
CPU: Intel i7-4790
Video Card: AMD XFX Radeon RX470 RS Black Edition True OC 4GB 256-Bit GDDR5 PCI Express 3.0

Surely this build should be able to handle 1080p recording. I can play DOOM flawlessly at 1440p with zero problems, it looks fantastic. It's JUST the recording that's total crap. However, like I mentioned, I DID do a 1440p recording back on 8-23-2016 that was great! But since then all of my recordings have been crap.

There has been an update to OBS I believe I installed since that day. And I also had an update to my AMD Video drivers yesterday if that helps, but surely this shouldn't be the issue? I've tried recording with downscaling, without downscaling, at my native 2048x1152, at 1440p, at 1080p, and they're all crap crap CRAP. LoL. I hope someone can help me once I get a log posted.

I'm uploading more logs. I adjusted settings again to try and help. I turned Vertical Sync OFF in DOOM as i read in several Steam forums this is recommended.
I'm downscaling from 1440p to 1080p in OBS. DOOM was set to use Vulkan API, but i changed it back to OPen GL because OBS was just frozen on the first frame when it was set to Vulkan.
But alas the recording was still choppy and complete utter crap.

Well so much for support... i uploaded 6 log files, and no one offered to help me. Guess I'll try X Split instead of OBS.
