- 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.

You can still use a capture card, or you can use NDI (which may work well because each VM will get a virtual 10 GbE interface, assuming the CPU has enough to encode and your GPU still has enough to render a single OBS scene with only the game capture).
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.
Oct 26, 2021 · If you want your recording process completely independent from the game and putting no load on the game GPU, you need to capture the monitor output with a capture card and use a 2nd PC where you do all encoding.
Jul 9, 2023 · Set up correctly, NVENC has zero impact on in-game performance, as it is a separate part of the GPU die. NVENC on the 20-series through the 40-series is virtually identical, other than the 40-series' ability to encode in AV1.
Dec 1, 2018 · While you can offload the encoding to the NVENC chip on a GPU, what you need to understand is that OBS still uses your CPU to run and handle all the scenes. With the most bare minimum setup...
Yes. Should you do it? No and here's why: First of all (in laymans terms): With the new NVENC encoder option in OBS Studio, the captured frame is kept on the GPU, if you have to move the frame from one GPU to the other GPU for encoding, you loose time and performance. Second:
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.
