Title: IR lags with VFB2
Post by: John_Do on 2025-02-20, 19:02:40

I noticed some significant lags during IR sessions with the VFB2, and not with the old one. It's annoying, am I the only one ?

Win10 22H2 / C4D 2024.5.1 / Corona 12.1

We did have some similar reports, mainly from Max users. Can you please update to Corona 12 Update 1 Hotfix 1 and see if it's still there? Also, what is your CPU model?

Hi Maru,

I'm already on Hotfix 1, and I'm using a 5950X.

You could try these, but we can't guarantee it will help:
- update your chipset driver
- update your BIOS
- disable core parking - https://learn.microsoft.com/en-us/answers/questions/1524213/remove-parked-status-of-cpu
- disable core isolation and virtual machine platform - https://www.makeuseof.com/windows-disable-two-virtualizations-game-performance-boose/
- change your power plan in Windows (try all available options, power saving, high performance, etc)
- fully update your Windows (probably upgrading to 11 would be a good idea)

Thanks for the help Maru, but I don't have the time to try these workarounds on a production machine. I'll hope for a fix in the next release and keep using the old VFB in the meantime.
