OBS streaming Issues with B580

[OmarFu]

Yesterday I finally was able to get a B580 from Ebay after a long 2-3 month wait, and I was excited for the upgrade coming from an RX-590 Fatboy that had LOTS of issues. I installed the Graphics Card, drivers and everything needed and it was a pretty good experience, almost double or even triple fps on some of the games. Cyberpunk at Ultra with Low Ray Tracing running at 60fps 1080p, RDR2 at Ultra running the same.

I was very happy until I started making some testing for what I bought the card for: streaming. I've tried with the QuickSync 264 codec at 6000 bitrate with the medium preset at the start and things started to get bad. I got from 25 to 95% frames lost due to rendering encoder lag. I've tried multiple options, changed the preset, lowered the bitrate, lowered all of them at the same time, and nothing really changed at all.

The game runs perfectly most of the time, maybe getting 5-10fps less when streaming or recording with the same codec, but OBS starts lagging like crazy and I'm getting laggy recordings. I've even tried lowering the graphics at minimum and it helps a little but I'm still getting lost frames.

I have ReBar enabled on the bios, I've disabled HAGS and enabled Game Mode already.

Here are my specs:

CPU: i7 8700k running at 4.3Mhz
RAM: 32GB at 3200Mhz
Motherboard: MSI Z370 Gaming Plus (ReBar Enabled + above 4gb decode enabled)
