G'day, kind sirs!

So here is what I have on my PC:

  • MBD: MSI Z87-G45
  • CPU: Intel Core i5 4670K
  • RAM: 16Gb Corsair Vengeance
  • GPU: ASUS GTX780-DC2OC-3GD5
  • SSD: 128Gb PLEXTOR PX-128M5S
  • HDD: 2Tb SEAGATE
I stream at 720p 60 fps. The problem is when i switch the preset to anything above fastest any game begins to freeze a little bit, which is weird because my PC is not all that crappy. What might be the problem and what can you suggest?

P.S.: yes, i've read the faqs and no i can't post logs because i'm not at home now.
 
There is no fastest preset. Are you referring to faster, which comes closest to fastest textually, or to ultrafast, which is the fastest x264 preset? Also, without a log, there's not much we can say about it.

If you are referring to faster, then there's nothing to really worry about. Encoding is a really intensive task for your cpu. You're already going above the recommended setting of veryfast, and combine that with a game that also requires its share of cpu power, you will start noticing it.

Oh, sorry, i meant veryfast oc. The stream looks nice when i stream BF4 (which is a resource-eater), but when I stream H1Z1 it's all about pixels. The game is not all that resource dependent and i should have no problems switching to faster in theory, but IRL it doesn't work so well.
 
Without a log, all I can really recommend is to watch your cpu usage, this gives you a pretty exact overview of which programs are using how much cpu during the stream.

The pixelation is probably because of the huge amounts of grass in all of those games, the loss in detail is immediately imminent, which is probably not as obvious in BF4, though there I'd still expect it to be pretty demanding on the encoder.

The way to fix pixelation is not really throwing a better preset at it though. This might make a minor difference, but it'll never fix a problem if you clearly see too much pixelation. The only thing that can fix that is to either use a higher bitrate, or lower your streaming fps or resolution.

TY, i'm gonna look forward into it and maybe lower my fps. And thx for the cpu usage tip, that will show me some new info to think about.
