Hi Vmix forum!

I am having about 4-5 framedrops/min. when streaming with hardware encoder on, but it runs perfectly with hardware encoder off.

Does anyone have the same problem as I have?

Kind Regards, Troels.

PC specs:

CPU: Intel i9 7900x
SSD: samsung mzvlw1t0hmlh
GPU: RTX 3070 Ti
MB: Supermicro C9X299-PGF

Hi Troels1902,

the same here. HP Z640 Workstation XEON 16 physical cores and NVidia RTX 3070: Dropping frames with hardware encoding turned on.

Doesn't matter if turned on for recording or streaming.

Since you also use a RTX3070 I'm wondering if it could be the graphics card? Hm, maybe drivers? Need to check on them.

Luckily, the 16 physical cores have enough power to encode 3 streams and record several H264 files in parallel and vmix only shows about 20% use of the system.
