Question / Help Playing and recording with different resolution

[Mambo]

Hello!

I recently started using OBS in video making and I'm still trying to figure out the optimal recording settings for my computer.

My monitor is 1080p but I am forced to record at 720p so that the footage wont get choppy.

I was wondering if there is any sense at playing with 1080p but recording with 720p. Will the result be better then playing with the same reso as I am recording with?

Also are my settings optimal for the computer that I have?

My PC:
Motherboard - Asus M5A97 EVO R2.0
Win 7
Hard Drive - Samsung 850 EVO SSD 500 Gt 2,5" SATA3
8gb DDR3 Ram
CPU - AMD FX(tm)-8320 Eight-Core Processor, 4000 Mhz
GPU - NVIDIA GeForce GTX 760
Monitor - Asus VE247H

My current settings:

Both Base and Output resolution is at 1280x720, FPS @ 60

Most people can record and play both at 1080p when using NVEnc recording, and the heavy lifting is done on the GPU. Can you post a log file attempting it for at least 5 minutes?

Sure, here is one:

Can you do just game capture, no window or display capture? Make your scene super clean to start out with.

Also, really do need 5 minutes of recording to have valid statistics, your recording attempts were only a few seconds long.

Change the profile to High and set 2 Pass to False / off.

The log shows more rendering lag (GPU) than encoding lag (CPU). So make sure your graphics drivers are up to date.

I turned profile to High and unticked Two-pass.

Played for more then 5 minutes this time. Here is the log:

13:28:25.697: Output 'adv_file_output': Total frames output: 27900
13:28:25.697: Output 'adv_file_output': Total drawn frames: 27877 (27928 attempted)
13:28:25.697: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 51 (0.2%)
13:28:25.697: ==== Recording Stop ================================================
13:28:25.703: Video stopped, number of skipped frames due to encoding lag: 22/27927 (0.1%)

The statistics look good. I'd say you're running about as well as you can right now.

Okay, so if I want to increase the framerate I should record at 720p instead?

 

[Mambo]

Bump!

 

[Boildown]

Maybe? Try it both ways and look at the statistics, and the video with your eyeballs. If the video looks good and the statistics don't show more than 1% of lagged and skipped frames on a long encode (5+ minutes of high action video), then you can probably do 1080p60. If not, then you should choose between 1080p30 and 720p60. Or maybe do one of the downscales between 1080p and 720p.
