Does any recording software have a huge performance drop while recording? How can it be minimized?

I have two r9 290's, an fx 8350 and 16gb of ram, but when recording the frames drop significantly sometimes to unplayable levels.

What do?
>>
What drive setup are you using? and what software? Pic related

I have an 8350 and 16GB of ram and have done some screen recording.
>>
>>46696174
drive setup?
>>
>>46696187
SSD, HDD, there's a bid difference especially with screen recording since SSD read/write times are MUCH faster than HDD read/write times. If you are writing and running from an SSD you can get away with good screen recording but with an HDD (hopefully you didn't listen to the whole SSD's don't much bit) it really affects those activies.
>>
>>46696217
Oh. I have ssd's and the program on one of them, but the save folder isn't. Should it be?
>>
>>46696246

I would run the game from the HDD and run the program and save to the SSD, as long as they're on different drives you should be OK. How are you doing it now? what program are you using? programs make a big difference. If pic is related I would try some other shit because I've never even heard of that.

Why did you even post? I hope you're more useful wherever you work. If you even have a job.
>>
>>46696104
Don't encode the video as you record: it completely rapes your CPU. Just dump it out raw then encode it afterwards.
>>
>>46696104
Is your bitrate too high? If you want to record lossless quality, you should use a software that lets you use Lagarith codec.
>>
>>46696347
Where do I choose whether I encode or not?
>>
>>46698486
I don't use Windows, so I don't know how OBS's settings are done, but there it should be in the settings somewhere.
I don't know if it supports outputting actual RAW video, but lossless h264 with the ultrafast preset should work pretty well.
It will rape your hard disk space though, until you compress it down.

AMD GPUs doesn't have hardware accelerated encoding?

there's an OBS branch that uses the hardware encoder on the card. use that instead.

>>46698578
they have for years. OBS just doesn't use hardware encoding by default.
>>
>>46698578
This is one thing their 8 cores excel at.
Get the fuck out
>>
Which bitrate and resolution are you recording at?

Lower the settings and test until you get zero frames dropped and CPU usage under 100%. I hope you're not recording in 4k resolution or somthing like that, then come on /g/ to ask for advice.
>>
>>46698620
no they don't
multimedia uses alot of floating point
and while your CPU has 8 ALUs it only have 4 FPUs so its actually have 4 cores when dealing with multimedia

8350 has 8 fpu's m8

Resolution?
>>
1k bitrate is pretty low man i go with like 3000-3500 for 1080p.
As for the lag you can change your cpu setting from fast to superfast to reduce lag. The faster the less cpu intensive.
>>

>>46698661
1080p, 60fps

>>46698663
Where do I change that?
>>
>>46696304
Why?

Nothing he said was wrong

>ssd has faster read/write
Correct

>the game should go on the hdd
Correct, only load times improve with a game being on ssd

>put recording software and save folder to the ssd
Correct, thr program will load instantly and save to the ssd without affecting your computer's preformance

Now what did he say that you disagree with?
>>
>>46698629
are you sure?
i can't find any info backing that up
amd page is strangely vague
>>
>>46698670
This doesn't make any sense. I probably have a much worse system (i5 mobile with 16gb, integrated graphics) and I can record at a higher bitrate and 1080p.

Are you recording on your PC or streaming too?

Do you have any other programs open? Better close any browser windows, especially those which run video previews. Close everything that takes CPU/GPU resources.
>>
>>46698684
By 'can' record do you mean without performance loss?
>>
Why just not use shadowplay?
>>
>>46698711
Well, I usually record at lower FPS (30), because I also streamed. So there is some performance trade-off, but my system is not top notch.

Yeah, if I record locally, I think I could do at least 2-3000 bitrate, 1080p and 60 FPS without frames dropped.
>>
>>46696104
>Winfags have to use this broken ghetto shit instead of ffmpeg -f x11grab
I can't stop laughing. Anyways, if you have an NVIDIA GPU, you can use ShadowPlay, and if AMD you can use GVR, either of which should have much better performance and quality.

I don't get what I'm doing wrong then, it drops me by like 20 frames.

I'm also trying to use this now >>46698666
>>
>>46698749
Oh, and keep in mind that ShadowPlay (and maybe GVR) only works for fullscreen DirectX games unless you have a desktop. On notebooks with Optimus, there's no way to do OpenGL/desktop recording.
>>
>>46698751
if OBS shits itself for whatever reason
http://www.amd.com/en-us/markets/game/downloads/raptr
AMD's official crapware program
Same shit as NVIDIA geforce experience shit
>>
>>46696104
OBS uses NVENC. that uses the GPU to encode and has not made a performance difference i could feel.
>>
>>46698751
Okay so with these settings I just tried recording dota 2 via monitor capture (since it's borderless windowed mode).

It drops the fps counter from 120+ to like 90-100, and causes it to be extremely choppy and annoying to play.
>>
>>46698767
>borderless windowed mode
11/10
>>
>>46698751
I dunno, OBS works very well with my crappy Intel graphics.

Maybe try with 30 FPS and downscale the resolution a bit. And open Task manager and watch how is CPU activity (or a GPU monitoring tool, if you have).

I changed from faster to superfast it's still choppy as fuck
>>
>>46698814
I'm gonna be nice and tell you to use fullscreen.
Next time don't make a thread for your dumbass questions.
We have a dedicated thread for those.
>>
>>46698821
idk what to tell you man, as long as your games fps is higher than or equal to your stream fps it shouldn't matter.
>>
>>46698830
Pretty sure I've had issues with fullscreen in other games, and unigine heaven.

But why is borderless window bad?
>>
>>46698833
he's using windowed mode and recording window, not game.
>>
>>46698830
oh and forgot to mention that setting will only work if you're using x264 as your video encoding option
>>
>>46698839
window capture vs game capture wont make a difference, what will is the x264 cpu preset, you could put it on superfast or higher but the stream will look like ass
>>
>>46698839
>>46698838
>>46698833
I tried recording dota2 in fullscreen with game capture, it's smooth with little frame drop.

I tried unigine heaven in full screen, and it makes it choppy as fuck and the video itself feels like it's 1fps
>>
>>46698875
>window capture vs game capture wont make a difference
It does.
>>
>>46698878
It also says WARNING high encoding C
>>
>>46698878
Unigine heaven is a fucking benchmark no?
no fucking shit you can't record that
what the fuck is wrong with you
>>
>>46698886
it will make a difference but not a noticeable one.
also you should never stream in fullscreen mode, i always stream in borderless window mode or window mode so i can pay attention to my chat.
>>
>>46698901
There's plenty of recordings of it on youtube

Just tried Crysis 3, it says WARNING HIGH ENCODING C and crashes without recording a frame
>>
>>46698914
It makes ALL the difference.
>>
>>46698914
It made a noticable difference for me man, from choppy unplayable dota 2 and shit recording to smooth on both accounts
>>
>>46696104
use fraps. Fraps has almost 0 compression. You'll have enormous file sizes, but performance impact will be small. Especially if you record at your current resolution, and at your vsync fps too.
>>
>>46698925
Wait I don't understand, what fixed it?
switching from windowed borderless to fullscreen,
or switching from window capture to gamecapture?

>>46698942
Those things are identical
can't use window capture on full screen and can't use game capture on windowed.
>>
>>46698942
Both, if I do window capture with fullscreen it just shows black screen.

But this clearly does not work for crysis 3 or unigine heaven right now, and displays a warning that I dont get (high encoding c)
>>
>>46698629

The 8350 has 2 effective fpu's

>>46698951
What about obs?

Turn off the aero theme while recording. OBS has an option for it in the settings. Should fix the problem.
>>
Okay so I'm using game capture and fullscreen

but it crashes crysis 3 and doesnt record shit

what do with that
>>
>>46698973
I'd try windowed mode or borderless window mode and window capture then.
obs crashes or crysis crashes? every time? thats wierd.
>>
>>46699006
Crysis crashes, and I guess the full error is warning high cpu usage
>>
>>46699013
Warning high encoding cpu settings
>>
>>46699013
Which OS are you using because i remember one of the streamers i watch was trying to play shadows of mordor on windows 8 but it kept crashing so he had to switch to windows 7. not sure if u use windows or which version tho
>>
>>46698967
OBS can use AMD GVR and NVENC

So its like shadowplay with much more settings
>>
>>46696104
I think it has to do with your power.
Not to sound like a shill but 2 top notch AMD GPU's and 1 AMD processor sure surge power
>>
Fuck OBS
>>
>>46699029
Windows 7

>>46699032
It kept carshing for me in crysis 3 recording under amd gvr

now I changed it to x264, andit records but with some performance hit although not too bad, but the video looks like ass at 3k bitrate 1080p.
>>
>>46699043
Are you trying to say it's surging? Are you retarded?
>>
>>46699069
sorry, I ment it is choking on power.
>>
>>46699065
because you set your cpu preset for it too high in advanced settings. I wouldn't go above veryfast if you care about quality
>>
>>46699083
It is veryfast

Also I just tried AMD GVR now from raptor, seems to have a minimal performance hit

I can't figure out where it saves the videos though, I clearly selected a location but the video isn't there. I can view it from the plays tv thing whatever that is.

Is there a way to record your desktop with this though?
>>
>>46698673
Kills ssd in 3 months of recording or even less
>>
Pirate a copy of Fraps or Dxtory
Make sure you have a lot of space for the video to be dumped to, it'll be uncompressed so a min of video can get up to a gig or so at 1080p.
>>
>>46698951
why is shadowplay so good?
>>
>>46699142
>3months
More like 3 years
Go ahead and try and find an SSD that has ever died due to the write cycles running out.
>>
>>46698626
jokes on you.
x264 is mostly integer.
>>
>>46698545

Bottom line. Record to your SSD.
>>
>>46699459

and how would I change it?

>>46696304
You've contributed shit all, retard. All you can do is act pretentious.
>>
>>46699142
>>46698673
SSD wouldn't speed up recording
>>
Drive speed doesn't matter if you're recording some low bitrate (any lossy) video.

Disabling DWM (desktop composition) can help a lot for higher FPS. You can't do that in Windows 8, though.

Should have gone NVidia. Shadowplay is pretty fuckin' sweet.
>>
>>46701600
if this doesn't work, change crf=15 to a higher number. it will result in slightly less quality, but it won't impact performance as much. file size will be large with these settings (still much smaller than raw video from fraps or similar)
>>
>>46698767
I hope you are using Game Capture -> [DWM] Monitor Capture you fucking faggot. They specificially state to NOT USE MONITOR CAPTURE because it will run like shit.
>>
>>46701157
how
>>
>>46699265
Because Kepler has an on-board H.264 encoding chip that is dedicated to that task and only that task (it doesn't borrow any processing power from anywhere else), so the only thing that impacts performance is the physical writing to the disk.
>>
>>46701656

>>46698724
Not nvidia cards

>>46701688
If you're refering to how game capture doesn't work with League, I understand but that's not what Game Capture -> [DWM] Monitor Capture means. It WORKS.
>>
Buy NVIDIA or Intel next time :^)
>>
Use the recorder from the Gaming Evolved client
>>
>>46701889
What? I said that since then I've used game capture and it worked smoothly for dota. It worked worse for crysis 3 though.

What do you mean (DWM) Monitor capture though, I just selected the specific application in game capture

I can already tell you have no fucking clue what I'm talking about.

Reading this thread is making me fucking angry because I helped a friend setup his OBS specifically for league as well and we nailed it on the first attempt.

Assuming you are playing a game using fullscreen, borderless windowed or a game that uses a launcher client like LoL:

Do not EVER use
>Add -> Monitor Capture
because it runs like ass unless Aero is turned off.

Instead, use
>Add -> Game Capture -> [DWM] Monitor Capture
because it is monitor capture except it is GPU accelerated

Using this will solve all your fucking problems especially with League
>>
>>46702077
Total black screen.
>>
>>46702795
Leave Aero on and just add "[DWM] Monitor Capture", turn on preview then see if you can see your desktop, nevermind the games.
>>
>>46701671
I don't think he gets high CPU usage from disk writes.
>>
>>46701671
AMD also has this.
