How to Bypass NVIDIA NVENC Limits on RTX Cards on Linux

It appears that NVIDIA has limited the number of NVEncoding streams on consumer GPUs. Guess it is so people have to buy the more expensive professional cards.

Fortunately, the limit is only applied to the driver, and there is a patch available that let’s us bypass the limiter.
