Question / Help 4K Window Capture for Destiny 2 lagging

Hello,

I'm trying to capture the game Destiny 2 at 4K for local recording and stream the game at 720p.

I have a threadripper 1950X with 64 GB of RAM, and a GeForce 1080 Ti

When I record other games such as League of Legends or Counter Strike: GO I don't have any issues as these Game Capture just fine. Destiny 2 has strict Anti-Cheat measures and won't allow Game Capture to hook as Bungie considers this process in general cheating (sigh).

I tried a Display Capture which was unusable, I then tried a Window Capture with the game in Full Screen window. In Full Screen windowed the game is buttery smooth, but the preview and recording in OBS is very laggy. I even tried setting the output scaling in video to 1080p with a base canvas of 4K and it is still just as laggy/choppy.

Here is a log from League of Legends which is normal

Any ideas?
 
Too much rendering stall. Looks like you let your GPU run into a bottleneck. Enable fps limit ingame and adjust ingame details, until GPU load stays under 95%.

This happens even when I run everything at x264 encoding which should be all CPU based right? I guess I don't understand why the GPU is coming into play so much here on a window capture

The game itself isn't taxing on the vram usage, but I guess that doesn't say much I suppose I can play around more with the ingame settings.

If I threw more hardware at it would that solve anything, like if I had a 2nd GPU dedicated to OBS would that resolve the issue or is it all due to in game rendering?

x264 vs. NVENC is only affecting your video encoding, not the scene rendering and scaling, which is always done via GPU.

A dedicated GPU might make things worse (most systems will reduce PCIe lanes from x16 to 2x8 with two GPUs).

Thanks this has been very helpful.

OBS uses the GPU to render your scene, as the GPU can handle that task very fast.

I wish there was a way to prefer CPU scene rendering as I have 32 threads to work with and my GPU is being utilized heavily by the game.

If I want to play the game at 4K HDR and record/stream at a lower res what would my best options be? I suppose I could look at a hardware capture card that does 4K, I have a magewell USB capture card, but it's only 1080p.

I've never used shadowplay, but would something like that be an option for acquiring the game video and feeding that into OBS? I hear that it works at the driver level and maybe wouldn't be as taxing on the GPU?
 
Shadowplay contains two parts which makes it so good
1. their own low level framebuffer access (they have two methods for accessing the frames with no additional PCIe load and very low latency)
2. NVENC encoder chip, that compresses those frames and put them into a video stream that will put very little load on the PCIe bus

That's why NVENC on OBS is still not performing as good as Shadowplay. OBS needs to access the frame buffer via DirectX which puts more load on the system (especially the PCIe bus) and additionally it needs to render the whole scene afterwards.
Only the NVENC itself can be used by OBS, which is nice for local recordings, as encoding via NVENC chip is not stressing your CPU and even the GPU load is only increased very little.
