Could, but it usually doesn't. I didn't find that to be the case for the types of games that only load 1-2 cores heavily (think sc2, WoW, wildstar, LoL etc) but it'd be problematic for stuff that would otherwise use the CPU resources - performance hit isn't correlated with cpu load

Happens in all games I've tried (WoW, Dota 2, SC2)
Go find the twitch.tv ping program that lists ping to all of the servers and updated (R1CH made it), leave it running for a minute and then try three of the servers with lowest ping/jitter. I've only had issues with one particular server usually there are problems related to it
I will probably end up making an OBS forum account at some point and figuring stuff out over there, but i'm wondering ATM if there's any way to record at higher than 120fps? I have a 144hz screen so i'd like to record some stuff @144fps, but i also wanted higher (even at lower resolutions) for some analysis before
Using Nvenc I go from 83fps to 72fps on the Thief benchmark, I thought since it was a hardware encoder that performance would not be lost and if so not by this much is this how it is or is it something wrong on my end? Using the GTX 980 on a i5-3570k.
If it's a GPU intensive game and you're trying to do something like 1080p60 with good quality preset, that doesn't seem all too weird - it's like a 13% performance drop, but frametimes will still be consistent etc. If you did 1080p60 with x264 it would be a lot worse (like a 30% drop, more inconsistent frametimes)
You could bench and see if it scales with resolution and/or FPS (maybe also nvenc preset)
It's quite possible that there is a scenario like changing resolution not really impacting performance, but changing FPS having a massive effect on it. I think it changes depending on the game and load, 13% does seem pretty high for NVENC.
Even if you take an 8-core CPU in sc2, dedicate two cores to the game and 6 to encoding, you could encode 1920x1080@60fps with veryfast preset and have very little load (like a quarter) and you'd still lose a third of your FPS and get less smooth game, so it's a strong improvement
What are the optimal NVENC settings for OBS? Filters, resolution, fps etc. I kind of want to do 1080 but right now I'm doing 720p60fps in Shadowplay.
My upload rate is 10mbps fiber cabled, so 3,5mbps which is what twitch limits is no problem I just need to learn of what the best quality filters and settings are since I'm only acquainted with x.264 in OBS. Also I have the GTX 980 so the new encoder shouldn't have any performance limitations afaik.

Does it actually work for you?
I can only guess at settings because NVENC in OBS has been horribly broken since i plugged in my 970. It's been difficult to benchmark or see what works, and twitch livestream level bitrates have been unusable (i set 3.5mbit bitrate with/without CBR, it laughs at me and uses 20mbit with perfect quality instead)
Try High Quality or High Quality Low Latency with 3500kbit CBR, 1080p30. There's not much else to configure
Will there be any plans to tweak the way OBS works on laptops and other machines that have both an onboard gfx card and dedicated card? OBS won't capture any applications that are being run on a different card. So for example, OBS runs off my nvidia card, but it won't capture mspaint or my browser, because they are all running off the intel hd card. The only fix is currently is for me to remember to force those programs to run using my nvidia card.
Hello, can someone help me with virtual audio cable ? I want te be able to stream dark souls 2 while while listening to the radio or TV on my computer, but I'd like OBS to not record TV sound, juste the game's. I have virtual audio cable because I know it can do that, but I just don't get how to do it.
I have been clearing up my place and managed to dig out stuff I no longer use but I'll cut the story short.
I have decided to set aside a dedicated streaming machine. Right now I am stuck between two choice.
1) Alienware M17X QX9300 8GB Ram laptop
Pros: It is a laptop so I can keep it anytime I want and less clutter and prepration needed as compared to Choice No.2
Cons: I am afraid it will not be powerful enough to handle OBS capturing it at 720/1080P 30/60 FPS.
2) LGA 1366 i7 Extreme 980X + Asus Rampge III Extreme + 12GB Ram
Pros: Very very strong 6 Core processing machine.
Cons: I will need to downsize the huge LianLi Tower case it is in right now and I definitely I want it to be a SFF system for space saving reasons. That reason alone means I need to buy a SFF case, an outdated lga1366 matx and then to set everything up at the end of the day.
- I personally am leaning to the Alienware QX9300 since I do not have to do anything to have it be a ready made dedicated streaming system but I worried that it might not be powerful enough to do its job.
Just try some 1080p30/720p60 on the laptop (or whatever settings you want), if it's using too much CPU for your tastes then buy stuff for the 980x system. It's OC'd? It would be like twice as fast even at stock
Wishful thinking: Perhaps maybe even a plugin that can count win/loss by parsing the replay folder that you can reset every time you stream also. This could be a nice feature on a lot of pro streams as well I think!
Hi, so I'm not sure if this is the right place to be posting this but I'm running into a slight problem and am wondering if I could get some help here. So I am running 2 monitors and one of them gets captured/recorded just fine. When I deactivate that and try recording the other monitor (or when I change it in the settings/properties to the other monitor), I just get a blank screen with a random color.
Pic: http://i.imgur.com/WV1NrwL.png On the right is me trying to capture one of the monitors. On the other side is the monitor that captures just fine.
I didn't have this problem on my previous set-up, which was a laptop with another monitor.
