Starcraft 2 with OBS Streaming

Post a Reply

sn0opys 12 Posts March 06 2014 03:52 GMT #1 Hi, I'm trying to stream Starcraft 2 (Everything on LOW) using Open Broadcaster Software on twitch.tv. The stream is perfectly fine but my gameplay is choppy and I am unable to perform as well as I could. My PC Specs are i5-760 2.8 Quad-Core GeForce GTX 650 Ti 2GB 8GB DDR3-1333 RAM Windows 7 Home Premium x64 and once again all the settings on Starcraft 2 are on LOW. I play on 1920 x 1080 while streaming on 1280 x 720 at 30 FPS. (Resolution Downscale) Max Bitrate on OBS is 3500 kb/s. Thank you in advance!

Now I'm just wondering if I get a better video card, would I be able to stream on Ultra? Or do I need to upgrade my CPU while I'm at it? Thank you for the replies! Also, this is my internet connection.

Find a replay with a big, maxed fight, put max stuff out aside from physics + reflections off, effects medium - then check your GPU load while running through it GPU will be at 100% load at start of game, but that hardly matters for performance in fights etc. My performance low vs max settings, as long as CPU settings are unchanged, is actually quite similar. I have a better GPU by a large margin, but CPU is also capable of running game at much higher FPS, so gpu has to be faster to keep up. Given your cpu+gpu, it wouldn't surprise me to see you not really gpu limited at all at times of low FPS
