Nu ma pricep foarte bine la programele de filmat dar eu stiam de unul pe nume Fraps sau ceva de genul.
Mai poti incerca xsplit, dar costa bani anumite functionalitati.

Dar din ce stiu, OBS era cea mai buna alegere ca performanta. Mergea cel mai bine. Posibil sa se fi schimbat intre timp.
Si sa stii ca pentru streaming la rezolutii mari ai nevoie de putere de procesare (adica un quad core).
"First, if you have anything less than a quad core processor, you may as well forget about streaming in any cand of decent quality for now. SC2 itself can easily almost max out a dual core CPU, leaving no room for streaming."
