Question / Help FPS downs from local recording 1080 60fps

[Azriel]

Hi all:

I'm trying to record local gameplay at 60fps and 1080, but every 5sec the fps ratio get down in game and in video result. Here's my PC build:

Motherboard Gigabyte GA-990FXA-UD3 (Socket AM3+)
Processor AMD FX-9590 4.7Ghz 8X
GPU GeForce GTX 780 Ti OC Windforce 3GB GDDR5
RAM G.Skill RipjawsZ DDR3 PC3-14900 1866 16GB 4x4Gb
HDD 1 Samsung 840 SSD Series 250GB SATA3
HDD 2 Samsung 840 EVO 500 Gb SATA3

I upload the last log file doing some tests, but with the same result.

Any idea? Thanks all

Your encode statistics look very good, but the problem is that you're taking a framerate hit in the game?

If so, I'd try limiting the number of threads that OBS (x264) can use to free more CPU time for your game.

Add a custom x264 option that says "threads=x", where you replace x with a number. By default on a CPU with eight logical cores (like yours), x is 12. So set it to something lower. I'd start with 9 or 10 and experiment values even lower. Make sure that you don't start getting duplicated frames by checking your log files, and make sure it actually has a positive effect on your gameplay. Experiment with the setting until you find the best one.
