Hello there. I am kindda new to OBS.
Yesterday I followed dodgepong's tutorial and made OBS stream to my rtmp server (a sheevaplug running debian+nginx), so now I can play and my little server records the game sessions.
But I wanted to decrease the performance hit. So I found this thread. My CPU is capable of Quick Sync (an Intel Core i7), so I enabled the stuffs on BIOS, installed the lastest Intel driver, etc. Now I have the Quick Sync option on OBS.
To test things, I ran Super Street Fighter 4 Arcade Edtion on my PC and let it make the benchmark. It scored about 221fps without OBS streaming or recording. Then I set OBS to stream to my server and benchmarked again. To my surprise, the result was pretty similar to what I had yesterday, before trying the Quick Sync technique. The performance hit was about 10fps on the benchmark.
Another thing, if I tell OBS to use my Intel HD Graphics 4600 as the Video Adapter, then OBS won't get anything from the game, be it in PREVIEW MODE or STREAM MODE. I thought would be normal, but then I checked the resulting video on my server and all I got was a black screen.
Can anyone help me with this?
Anyway, congratulations for this improvement in OBS and to trexid for posting these tips.
P.S. - My config:
CPU = Core i7-4770 @3.4GHz
GPU = AMD Radeon HD 5850
RAM = 8GB DDR3 @1600MHz
