So I tried to use the Quick Sync Technology and I wanted to give my feedback.
This post is not complain or anything just wanna say what i have observe while i was testing things with Quick Sync so I can help a bit the Dev Gods to Improve the OBS even more!! :)
My PC specs:
i7 2600k 4ghz,
8gb ram
Ati 7950 windforce 3gb
PSU Corsair TX750M
mobo gigabyte GA-z77-D3H rev 1.1
main monitor LG 23'' 1080p connected via Hdmi
second monitor AoC 19" CRT 1600x1200 but i use 1280x1024
"fake monitor" resolution 1280x1024
camera logitech c920
Browser: Chrome
Firstly I Did enabled Quick Sync with the "fake" detection method.
I noticed that my CPU wasn't effected at all on streaming. The Details were Good Enough at 720p @60fps and 4200kbits . only a few artifact squares when i was moving too much.
With the use of CBR and CBR padding. When i deselected CBR i noticed that the encoded video (I rewatch the videos and have fraps on to have an estimation of fps) was limited to 30fps and sometimes it was going for 2 sec up to 40-42 and then rapidly at exactly 30... like it was a frame limiter on or something. the videos with CBR on were all at 60fps.
Also i have noticed that if i re watch the videos immiedietly the quality is not so good (twitch) but after 1 hour the quality is alot better..maybe twitch.tv does some encoding itself i dunno... maybe its just my imagination :p
also when im streaming and in another window I watch what im streaming ,the in game fps droping to 30fps again like i have some kind of frame limiter on. when I hide/stop the video (twitch dashboard) the fps goes up and steady at 60 (with vsync on). I thought it could be by cpu stressing or something,but my cpu was not high enough to limit the ingame fps with the video play on or off.
I monitoring in the second monitor CPU load,GPU Load and iGPU load.
Cpu goes up to 60% with indipended cores going up to 70-75%
GPU goes everywhere between 40-100% but when im testing the "fps droping" the gpu is at 60%
iGPU is at the most 35-40%
Anyway i could live with that little issue...so next thing i wanted to sort out was the fake detection of the third monitor with the use of igpu. so i decided to connect my second monitor to the intergrated gpu. everything perfect and i didnt loose the mouse on the edge anymore :p the only change so far was that iGPU load was a bit higher 40-55%
Everything worked as before with the fake detection Except one thing. When i tried to watch what i was streaming while i was streaming it, the ingame fps droped to 15fps. steady again like i had enable some fps limiter. GPU didnt changed the load at all,igpu the same only the cpu was like 10-15% higher load (still under 70% load) due to HD video playback. When I stoped the playback of the video everything gone again smooth at 60fps. So I suspect that OBS need some optimize on Quick Sync still.
I decided for Now to enable the Quick Sync via the Fake Detection so I can check what im streaming now and then, without making the game completely unplayble.
BTW do you think I have done something wrongly that i could change in order for all to be perfect?
My monitor is at 1920:1080 i play at the same resolution but im streaming at 720p with the resolution downscale.. is that the right way to stream at 720p? oh and what about those filters on the downscale..do they have some effect with quicksync? (bilinear,bicubic,Lanczos) I use the Lanczos.. not sure if thats better..u tell me :P
Thanks For all that good Work and hope to make it even better! :D
sorry for my poor english..im greek..
PS: Now that the encoding being done (mostly if not all) by my iGPU Quick Sync tech, i could have some fps improvements ingame if i turn the Hyperthreading off again? My Game is Guild Wars 2.
