Question / Help Can't get Stable 60fps with C985

Hello everyone,

I'm desperately looking for help. I had an AverMedia LGX but couldn't get that to keep a stable 60fps in either OBS or RECentral2 so I've returned it for a refund and got a Live Gamer HD Lite yesterday. I'm trying to stream console games

For some reason I can't get a stable 60fps when recording with the capture card in OBS. It stutters for a few seconds every 15 seconds or so. I tried both adding it as is and through stream engine, lowering the encoding preset, setting fps to 59, using buffer and increasing scene buffer. CPU is between 50% and 60% on the veryfast preset. I have the current drivers installed and update the card's firmware to the current version and it does work just fine in RECentral. I will check if my display puts out an actual 60hz when I get home.

Here's my specs.
Intel i5 2500
4gb RAM
Intel HD 3000 <- could this cause the problems?

I will attach a logfile in a few hours once I get home, looking through it it had no duplicated frames and only a tiny amount of late frames.

Thanks in advance for any help ;)

I did try checking the refresh rate of my display as someone suggested in another thread, it showed 59.95 changed it to 60 in the EDID but still nothing

will try to put it into a different pc with a 2500k and 8 gigs of memory next. unfortunately I'm unable to fit both the capture card and a graphics card into the same computer at this time.
 
  • Tried downgrading the driver to an older version - still the same
  • Tried putting it in the other PC - still the same. Although I consistently get 0 duplicated frames now.
  • Tried recording at 30fps and I still get very noticable stutter.

This card gets recommended here all the time, I feel like there's got to be something wrong on my end.
 
I shamelessly bump this to let y'all know the stutter is fine when selecting the baseline encoding profile.
Hopefully someone can tell me where the bottleneck is with this information.
 
Not that I expect an answer at this point but here it goes.

baseline has not "fixed" it, that was due to me setting the capture card and OBS-MP to 59.94 fps which makes the stutter less noticable but it's still there.

I finally got around to testing it with a dedicated GPU which made no difference whatsoever. It's kinda strange that this card gets recommended a good deal on this forum yet it's full with ghost threads like this where no one even bothers to respond.
 
The problem has apparently been traced to bad drivers and software in the latest package (according to some people)
 
Thanks for taking the time to respond Harold.

I've already heard about the driver issue. Unfortunately I couldn't get an answer when asking which version works on another thread or even by pming the user who made the post.

As I stated in the OP I tried downgrading the driver but unfortunately the earliest driver causes a code 10 error on my windows 7 machine. Installing the driver on windows 10 has not fixed the stutters
