FF plugins running at low framerates

Hi All,

I'm running Windows 10 i7-9700k, 16 gb of ram, nvidia rtx 2070 in Bitwig 4.2 w/ version 3.21 of all FF vst 3's

I've tried turning off graphics accel in the registry and my drivers are all up to date. But, nothing seems to fix these VSTs looking so choppy.

It doesn't happen in FL or Ableton.

Any thoughts?

Hi Darkovon,

Could you see if changing the Plug-in Hosting Mode in Bitwig makes a difference? You can find it in Settings/Plug-ins

Hey! Any update on this? Pro Q 4 seems to work just fine but Pro C 3 seems to run at a low framerate compared to how I see it performing in videos of others using it. I also have a decent PC, CPU, and GPU and haven't had this issue otherwise so I was surprised.

Hi Ferzam,

We'd need a bit more info on your system. What OS/DAW versions? Can you send us a small video to info@fabfilter.com?
