finally fixed it (sort of) - in the ReLive-tab of Radeon Settings i changed the Audio Bitrate to 96 KBit/s - this solves the issue - but a little delay remains (about 20 to 30 ms, but you'll only notice this when you check the recorded clip in a video editing software and see that there is a few ms of blank audio at the beginning
tested this in PUBG, Soldat (soldat.pl), Game of Thrones (Telltale), Left 4 Dead, Portal and MechWarrior Online - all work problerly now (with this little delay)
Why does that matter? Also, one question if you could answer it, is it possible to record a stretched resolution in a game like CS:GO but have your video be 1080p (essentially, have no black bars).
One more thing is that when I try add a custom resolution and save it, it doesn't change, my monitor is still in 1080p and I can't change it. Do you know a solution? 3 questions lolol
If you are using a 60hz monitor and V-Sync, you'll get always 59/60 fps, to record in 60fps you need more than 60, try to set 30fps in relive and check the audio sync ;p (record this Audio Video Sync Test - YouTube and slow it down via editors)
About black bars, 16:9 monitor with 16:9 res = no black bars, 16:9 monitor with 4:3 res = black bars, 4:3 monitor with 4:3 res = no black bars. Anyway I was able to get LEM rank in csgo with 16:9 and max sets, so it doesn't matter what res you are using, just change the crossair and the FOV/Weapon Position
To change res use Windows: right click on the dekstop, screen options, resolution and you'll see every res your GPU can support.
You can use Radeon Settings to try to OC you monitor by adding Hz... PS: TV Monitors aren't good for OC.
After 2hrs of tests, I find out that now there's a little sound delay, it persit no matter what settings I change, It's very small, only noticeable by slowing down the vid to 10/20%
This seems to occur only with games, dekstop 30fps have no delay.
I don't know if is drivers fault or Windows that f***ed up like always, but I can't find a fix other than edit the audio manually.
I'm going to update the guide, sadly :c
