Question / Help Live Gamer HD locked to 30fps when using OBS

Hey guys, I just got the capture card 3 days ago and as the title says it; no matter what I change, how I tweak the settings, it just won't stream at 60fps! HOWEVER, with Recentral, I tried and it does stream at a smooth fluid 60fps but only for a couple minutes, after that my stream will go black and keeps on loading.
I stream in 720p@60fps
Using OBS only(no capture card), everything is OK, 60fps with the drop of frames here and there but that doesn't bug me.
When I use the Avermedia as the capture source though, it only captures/streams at 30fps.
If I open twitch video playback stats, it will obviously say 60fps because I set the fps to 60 in OBS and this is what OBS encodes and sends out but the capture card is actually capturing only 30fps or even less but I know it's NOT 60fps!
Here are my specs:
  • Motherboard: Asus M5A99FX PRO R2.0
  • CPU: AMD FX-8350 8 Core at 4.0Ghz
  • CPU Cooler: Cooler Master Seidon 240M Liquid CPU Cooler
  • RAM: 16GB(2X8GB Corsair Vengeance DDR3)
  • Graphic Card: EVGA GeForce GTX 760 Superclocked 2GB GDDR5
My OBS settings are as followed:
Encoder: x264 with CBR and padding
Max bitrate (kb/s): 3500
Custom Buffer size checked: 3500

Audio Codec: AAC
Bitrate: 128
Format: 48khz

Base Resolution: 1920 x 1080
Downscaled to 720p
Filter Bilinear (fastest)
FPS: 60

Advanced
Use Multithreaded Optimizations checked
Process Priority Class: Normal
Scene Buffering Time (milliseconds): 700
x264 preset: Faster
Encoding Profile: high
Use CFR checked

As for the Avermedia HD Capture C985 in OBS, these are the settings
Custom resolution checked: 1280x720
FPS: 60.0002 (tried changing it to 60 but always adds the .0002)
Everything else is default.

I'm fairly new to OBS so I don't know how to get a log file, help again please?
Thanks guys.

Why are you using Stream Engine? Just add the card as a video capture device. I've also seen some posts complaining that the latest AVerMedia drivers (from their "GamerZone" website) seem to be related to this problem, so maybe try rolling back to the most recent package from http://www.avermedia-usa.com/avertv/product/ProductDetail.aspx?Id=513&tab=APDriver instead.

Hi, thank you so much for your response. I was trying out every possible way I know to make this work and that is why I was using the Stream Engine. But even with the card as a video capture device I had the same issue.
Yes, I am using the latest driver and I will try rolling it back tonight as I am currently at work.
Thank you again for your reply.

Hi 8LAZ3,

This just started cropping up over the past couple of weeks. It is a very big issue that not everyone is noticing.

(see here https://obsproject.com/forum/threads/dedicated-streaming-pc-help.33317/ and here https://obsproject.com/forum/thread...-hd-locked-at-30fps-when-set-to-60-fps.33728/)

The problem is the driver rollback only 'appears' to fix the issue.

If you stream at 720p 60fps it will look fine for the majority of the time but periodically you'll get drops to 30fps - and these can last seconds or minutes. Sometimes it happens a lot, sometimes you can go an hour without a hiccup.

Something is very, very wrong.

Hi, Sapiens, you were right! An older version of the driver worked fine, I'm not really sure if it's really 60fps cause when I look at the stream again, it does not "feel" 60fps but whatever, it's smooth and much better than before! Thank you so much guys!
One more question: I have the Asus VG248QE 144Hz, now using the capture card as a passthrough I am obviously limited to 60Hz, my question is will a simple DVI splitter solve this problem or do I need something more advanced to carry "2 different frequencies"? Sorry if that makes me sound stupid.
