Hi all, would like some advice as to what sort of settings I should be using for OBS to not stutter like a slideshow.

First up, computer specs:

CPU: i7 8700K 3.70GHz OC'd to 4.40GHz (https://i.imgur.com/JNogVKW.png)

RAM: 32GB 3200MHz DDR4 G.Skill Ripjaws V (https://i.imgur.com/xhmyjdf.png)

GPU: ASUS ROG STRIX GTX 1080 Ti GAMING OC (https://i.imgur.com/ODhW7Mp.png)

Game Drive: Samsung SSD 960 Pro 1TB NVMe SSD M.2

Recording Drive: Seagate FireCuda 2TB 7200 RPM SSHD

Gaming Monitor: ASUS ROG Swift PG27AQ 4K G-Sync Monitor

Second Monitor: Acer V243HL 1080p LED Monitor

Recording Software: OBS Studio 23.1.0 64-bit

Recording Settings:

I play games in Borderless Fullscreen/Maximized Window most of the time, and would like to record my gameplay at 4k60fps downscaled to 1440p60fps. However, while the above settings work wonderfully for my Android emulators, I still get extreme amounts of dropped frames when recording bigger games such as Tom Clancy's Ghost Recon Wildlands and Assassin's Creed Unity.

Here is a sample video: https://www.youtube.com/watch?v=MVxNbQyNW80

I thought my machine would be capable of much more than that. Did I overestimate my machine? Or am I just not using the right settings?

1) Disable Windows 10 Game Mode unless you're running the latest version 1903;
2) Under "Advanced", switch to the default colour format: NV12, it's the default for a good reason;
3) If you're just recording, use NVENC encoder set "Quality" preset, disable "Lookahead" and "Psycho Visual Tuning" and set CQP to somewhere in the 18-20 range;
4) Keep one capture source per scene collection, as additional ones added do incur of a performance hit;
5) Stick to "Game capture" since it's, by far, the fastest capturing method for games, unless there's some other factor preventing you from doing so.

After making these changes, test again and come back with a log file of a recording session if you're still having issues. 4k gaming +1440p recording requires a whole lot of resources to do well so some additional tinkering might be required.

Based on your latest log, rendering and encoder lag still present suggests that your graphics card is being overworked, which means you have a few options available:

1) Limit your ingame FPS by using VSYNC, ingame FPS limiter or Rivatuner to 60;
2) Reduce ingame resolution and/or graphical settings until you have some GPU resources to spare for OBS;
3) For troubleshooting purposes, turn off GSYNC.

Those games mentioned aren't easy on modern hardware and pushing 4k resolution isn't helping, even with a 1080ti.

When testing, could you try creating a completely new scene collection and adding only "game capture" source, for troubleshooting purposes?

2) I run the game in Borderless Windowed, so I'm guessing that there's no way I can modify the resolution. The game was on Medium preset, turned down to Low. https://i.imgur.com/355ZcyS.jpg

I should probably mention that the nice folks over on the OBS subreddit have informed me that no, my hardware setup is nowhere near close to being able to record 1440p while playing at 4k. So I guess that's the question answered?

That said, the video I just uploaded looks really smooth. Looks like the Low preset did major work in making things better. There was also a huge filesize increase: The previous video I uploaded was only around 19.5MB. This one was 995MB. I'm guessing because it's capturing all the frames instead of losing them?
