NvEncoder Open memoryexception error

[osguligit]

I've create multi nvencoder with multi resolution.

4Encoders resolution is each by "4096x2160", "704x480", "1920x1080", "704x480".

With "T4", it work run well.
But with "RTX 3060", can't run.

"RTX 3060" can't run well 3encoders with "4096x2160", "704x480", "704x480".
but when i run as 2encoder with "4096x2160", "1920x1080" -> it has error

• errors info:

You have resources to run 20 4K sessions, but
Nvidia decide to allow you only 3 sessions on non Quadro devices.
This is driver limitation search for patched driver.
