Hey

So i recently started recording and i noticed that my recordings of games like Fortnite get a bit laggy while i dont really notice much lag while i'm actually playing at all.So hopefully someone here can help me setup OBS better so my recordings wont lagg anymore.

PC Specs:

Operating system:
Windows 10 64-bit

CPU:
Intel Core i5 6600K @ 3.50GHz
Skylake 14nm Technology

RAM:
8.00GB Single-Channel Unknown (14-14-14-35)

Motherboard:
MSI Z170A PC MATE (MS-7971) (U3E1)

Graphics:
PL2788H (1920x1080@60Hz)
3072MB NVIDIA GeForce GTX 1060 3GB (Gigabyte)

Log file:

I hope thats enough information to get an idea of what i'm doing wrong.

Thanks in advance

I don't know if I'm reading this right, but is your bitrate set to 0?
I don't use OBS for recording, only streaming, but there my logs show the bitrate I've set.

I dont think i have it set to that. If you are talking about recording in the output tab. I have that set to CQP and 18.

guys its ok its cqp :P

quote from QSV guide:

CQP: constant quantization parameter algorithm
Use case: recording with a variable bit rate
Description: Video is encoded with a constant quality, regardless of motion. Bitrate is determined by the complexity of the video material. Quality is determined by QPI, QPP and QPB parameters. QPI determines intra frame quality (known as key frames), QPP determines predicted (P-) frames quality, and QPB determines h.264 B-frames (a weaker version of P-frames). You want to use the same value for all 3 parameters.
Remark: Very good for local recording for raw footage, since quality is not restricted to bitrate if you set the bitrate high enough, while not wasting disk space on low complex scenes.
Quality is determined by the 3 QP parameters (1..51). The lower the values, the better the quality. 0 uses SDK default. Sweet spot is probably around 20-25. My choice is 22 with a maximum bit rate of 50000, which results in an average bit rate of about 29000 while keeping high complex scenes at maximum quality. Lower values than 22 greatly increases the bitrate requirement.

So does that mean i'm fine to leave it on CQP and 18? But if thats fine then i dont understand where the lagg in the recording comes from.

i wrote about vsync earlier. do you have it enabled in game?
yes cqp is fine, but 18 may be a bit overkill and result in bigger than needed files. usually 21-23 is enough. lower number-higher quality-bigger filesize

btw change preset to high quality, profile to high and enable 2pass

vsync was not on by default i'l let you know next time i record the game if it makes a big diffrence. Also i turned on 2pass but i was told that if you are only recording it does not really do anything.
