Hey my computer specs is
I5-4460
ram- 6gb
gpu- rx570
i need to find best setting for streaming
Even with 16GB or RAM, a 4th gen intel is 11+ generations old, 4 generations too old for Win11 and Win10 free support ends in Oct of this year. And you are trygin to do computationally intensive real-time video encoding.
Numerous other threads on equivalent ancient hardware (great for many things, real-time video NOT being one of them)
Can it be done? with expert level knowledge and tweaks at Operating System and OBS Studio level... maybe. depends on specifics, expectations, and background workloads..
