I'm occurred a performance issue with the new vrchat client. I saw some frame stuck/jitter once per 10 secs/minutes. Also I got a very low frame rate in a 30 people world and even more worse after I back to default home, and back to normal after I restart the game client ....
Or in other words:
  1. When start the game client, the frame rate may is 90 in normal home when I'm alone, and sometimes it goes to 50 or less suddenly. If I goes somewhere, sometimes down to 30 or less and results a frame freezing (for a very short time then back to normal), in the same world with same people.
  2. If you come to a 30+ or more people instance, maybe your frame rate will goes down to 40 or 30, but when you go back to the default home, it will also is 30, and I saw sometime it is less than 15, and after I restart the game client, it returns to 90.

Note: I also hear my friend met this issue tonight, he use Ryzen 9800X and rtx 5080.
I can give the game logs here if necessary.
