Re: 720p50 3500kbps twitch.tv OBS

@annihalator 

IF you really want to use AMD AMFenc
download: https://github.com/Xaymar/obs-StreamFX

set it like this:

with custom settings:
-usage=2 -quality=2 -profile=100 -level=42 -rc=1 -preanalysis=true -g 0 -coder=1 -qmin=21 -qmax=51 -me_half_pel=true -me_quarter_pel=true -vbaq=true -intra_refresh_mb=170

tested AMD AMF with Apex and 720p@4500kbps - it looks like trash xD

so dont use it 😉

Re: 720p50 3500kbps twitch.tv OBS

@annihalator 

loss of 40fps is not that bad - you will still get well over 100fps
have in mind - games like Apex you play with 1080p 100% renderscale and low

if your CPU handles more stuff it cant handle more of Apex - and you are streaming
thats why i use NotCPUCores as the game still runs on physical cores while OBS with x264 runs on the "weaker" SMT cores

btw - you dont want to stream Apex with AMD AMF (settings for StreamFX provided - StreamFX uses FFmpeg to use HWacc AMD AMF) you still cant play the game on ultra because AMF also needs some ressources AND the stream quality is 10-15% worse than with x264. So fast high motion games like Apex or CounterStrike etc should always be streamed with x264 (and maybe NVenc on RTX 2000 or better)

why use StreamFX and not AMD AMFenc directly from OBS?
StreamFX and AMD AMFenc for OBS was both coded by Xaymar
StreamFX has the benefit that it uses ffmpeg and allows custom settings - you squeeze out 5% better quality with the settings i provided compared to "standard" AMF

but as i said - DONT USE AMF for games like Apex - the bitrate twitch.tv allows is not big enough to make it look good

streamFX - download from github (like provided) & install it into OBS

you have an RX 570? i think you should get more FPS in Apex while streaming

Re: 720p50 3500kbps twitch.tv OBS

@annihalator 

believe me - the quality is 10-15% lower with AMF when compared to x264

also i check what performance i get - but when i had time to test Apex Servers were down

my Ryzen 7 2700X gives 100-130fps when streaming and 110-140fps without streaming 😉
