Achievable framerate?

[Net-time]

Hi, just installed an old version of Micro-RTSP from hacksterio, as I'm new to this, Arduino IDE seemed like the simple way to program directly to the usb port.
Http streams fine but rtsp have difficulties with fast movement, just wondering if you can achive VGA at 12.5 fps?
My module "M5Camera/b" has psram is that used with your code or can I fake it by using the ttgo config?
