Question / Help Second GPU for render scenes

[George B.]

So i just upgraded from an i3 4160 to a Ryzen 5 2600 but i still have a GTX 960.In games like Fortnite/overwatch i can just lock my framerate to 75(my monitors refresh rate) but in some other games like pubg or rainbow six my gpu is always almost at 99%.Because of that my games run fine but my stream drops frames down to 10-20fps.i have a really old GT430 laying around somewhere in the house.Can i use that to composite and render scenes ?I'm still gone use x264 for my cpu and use the GTX 960 strictly for games.

You could, but you would be crippling your performance even further and getting nothing in return. All that would happen is that you drop your PCIe bandwidth in half for your 960, and introduce a new required data flow path across the PCIe bus to transfer frame data between cards instead of just dumping it from the frame buffer to VRAM on the same card.

The GT 430 will be severely overloaded with even OBS rendering a scene. It has about 10% of the rendering power of a GTX 960. Just let it stay in that dust drawer. It might make a nice wall art, but don't put it in any reasonably current PC you intend to use for video stuff. It's just enough to display a Windows desktop and some office software.

Worth pointing out that even if your second card was another 960 you could not use it for this purpose. There are multiple threads on this already; trying to get OBS to render frames on a separate GPU than the captured application causes more bottlenecks than it solves.
