Question / Help Can someone with i7-4790k & L4D2 help me with a test?

[PrinceVinc]

A friend of mine has a i7-6700k and I have i7-4790k. He has GTX1070 I have 290X.

Following Issue. We both record with OBS.
He uses the simple method with "Indistinguishable Quality" and I use Advanced with Preset: Veryfast and and CRF 23.
We both record with 1080p@60FPS

Yet when we play L4D2 I get FPS dips while he claims that he has none. When I am not recording I can get about 120+ FPS but when I record it fluctuates and occasionally even goes below 60.

OBS does NOT say high Encoding.

I already tested Temperature with Core-Temp Program. C° about ~62

The CPU Load is around and above ~60 - 70% while recording, depending on how much is going on, on the Screen.

Could someone be so kind, who has a i7-4790k and the game (max settings) test my Settings with their CPU?
Telling me what the Load in Core-Temp says?

My friend says there might be something wrong with mine... cause his CPU is of equal Power without suffering from this kind of FPS loss. I mean can it really be my GPU even though the issue is not present when I am not recording?

Please post a log from a recording session where this occurs. It would be most helpful if it included the profiler information at the end of the log, so either upload it manually as an attachment to your forum post, or upload the last log file using the built-in uploader. If using the built-in uploader, do this:

1. Record your gameplay.
2. Stop recording.
3. Exit OBS.
4. Open OBS.
5. Upload the last log file (Help > Log Files > Upload Last Log File).

That said, yes, it could be your GPU. OBS requires some GPU resources to render the output frames and output them to the encoder, so running the game and OBS is going to take up more resources than just running the game. The GTX 1070, as far as I can tell, does outperform the 290X, so it wouldn't be too surprising if your friend has fewer issues than you in this regard.

The log file should tell us more. It would be a bonus if you could also get a log file from your friend for comparison.

I found out the Problem...and it was the dumbest thing ever... Multi Adapter Compatibility.... I don't have Crossfire/SLI... I just actiavted it cause I thought it would make games less likely to crash with OBS >.< serves me right I guess... Assuming things...

 

[RytoEX]

Glad you figured it out! For future reference, a log file would have had that information in it, so someone could have answered this much sooner with one provided. Always provide one if you're having an issue with OBS, as they're really quite detailed.

For the future and more performance intense games I would suggest using the ultrafast Preset.

Please don't make blanket statements like this. That is just terrible advice.

Please don't make blanket statements like this. That is just terrible advice.

So you rather suggest to record x264 with 1080p60 on veryfast then let him try recording actually graphical and cpu intensive games so he reopens the answered or even starts a new thread for the simple answer? What has this Forum become for general guidance or suggestions.

Local recording and file size is more important than the general performance hit while using x264

For local recordings and using x264 it's good advice.
Though for recording you might aswell use a hardware encoder.

 

[RytoEX]

Using ultrafast or a hardware encoder comes with the added caveat that the files may be larger. If they're recording a lot of footage, that can add up fast. If storage space is not a problem for you, then this is fine. However, if the computer can handle x264 veryfast recording, there's not much need to switch off of it.

@Fenrir seemed to be saying that the blanket statement of using ultrafast for recording every intensive game without considerations for other factors is bad advice. That doesn't mean that using ultrafast is a bad idea altogether, just that it doesn't help someone much if they don't know why to use ultrafast or what it would also do (use more disk space), especially when their system might otherwise be okay on veryfast.

While @alpinlol asks what would happen if a user overloads their CPU trying to record a resource intensive game on veryfast and needs to make a new thread for a simple answer, what about a case where a user notices the recorded files on ultrafast are large and wants to know what to do to make them smaller? Or in another, case, if the user was recording in CBR (by accident, perhaps) and wondered why their video quality looked terrible on ultrafast. In any case, if a user came back to make a thread to get a simple answer, I'm sure someone capable on these forums would answer them.

Yes, that was more my point. Just making the blanket statement to use ultrafast (what if they're using CBR and not CRF?) is just bad. Thanks for clarifying for me, I hadn't had time to respond myself yet :P

Yeah, I use x264 for the very reason that I don't edit my Videos in a non-linear Editor.
And mostly put them straight up to YT.
So the Filesize is very important, that's why I try to stick with Veryfast every time I can.
If it introduces huge FPS Impact I go superfast.

And I make sure to add log next time xD
