- Yes, if you have one GPU, it is driven by x16 pci-express bus speed. But if you insert a second one, both cards are driven with x8 speed. Consumer CPUs aren't designed to output 2 cards simultanously with x16 speed. They split the data transfer to 2x8, one x8 for each separate card. If you have 3 GPU cards, you get 1x8 and 2x4.

How does OBS work?
OBS uses the GPU of the monitor it's being rendered on, so you'd need to plug whatever monitor you usually use for OBS into the 970. Another alternative besides using a capture card on a separate PC, in my opinion, would be to set up your PC with Proxmox, where you have two Windows VMs.
May 23, 2023 · If you have an Intel CPU and running the game on an external GPU, you can use Quicksync on the iGPU as encoder, which is effectively offloading encoding to a different GPU. Using Quicksync on the iGPU isn't wasting that much resources as using a hardware encoder on an external GPU.
Aug 22, 2018 · Yes, if you get separate GPU for encoding, you still get dropped frames if the GPU OBS is running on is on 100%. And you cannot set priorities on the GPU (see the edit of my previous post). Now you might think you can try to run OBS on one GPU for composing and your game on a second GPU.
Oct 26, 2021 · NVENC is a separate part of the GPU core and does NOT use *any* game-rendering assets. The only time you'll see 'encoding overloaded' with NVENC active is if you're using the Max Quality preset (use Quality instead), Lookahead or Psychovisual Tuning (turn them OFF).
Encoding with nvenc will work like a charm. The only way to use 2 video cards for streaming without hidden problems is 2 pc setup with capture card. The 2080 has a very good encoder, 960 has a mediocre encoder. In your case, it is better to limit the frame rate in games to 60 fps.
Using the NVENC on your GPU won't impact gaming performance, as the hardware encoder is its own part of the chip. Whether you use the NVENC or not, won't bother the rest of your GPU (unless you use 2-pass encoding/Max Quality preset, lookahead and/or psycho-visual tuning options).
Jul 11, 2023 · However, identifying the optimal encoder settings can be a challenge, especially given the myriad CPU/GPU combinations. To help you navigate through this, we'll recommend specific OBS encoder settings for 10 of the most common CPU/GPU combinations in PCs and Macs, focusing on 1080p streaming.
