Multilevel L0/L1 references now not working
#3
Thanks, my features look the same as your RTX 4080 except for mine not supporting AV1 at all. Everything else looks identical.
When I used Hybrid some before my current install the Multilevel Refs could be selected one minute and then just after they could not be used. I tried uninstalling, reinstalling and replacing the settings files which did restore the Multilevel Refs for one encode and after that they became unavailable again until I closed Hybrid and replaced the settings files. Very annoying doing one encode and having to repeat the process. Now I have been unable to use the Multilevel Refs at all on this current Windows install.

I can see that my NVEncC is an older version than the one that you are using, 7.21 compared with 7.31. If you need any further diagnostic info then you only need to ask.
