We run the encoder example encoding h265 with --stats flag to see fps measurements.

we also start andstop gdm service using:

systemctl start gdm  
systemctl stop gdm

**When gdm is running the fps around 385 BUT when we stop gdm the fps is 60!**

We run jetson clock so the encoder run with max performance  
We attached screenshots of encoder mmapi example with and without gdm running

Hi,  
Please upgrade to Jetpack 6.2.2 r36.5. We have critical PSIRT fix in the version.

And then please apply
