yes, possible, but compare something with that code / lib / link to a non existing IP cam
is difficult.
but i have a nice stress test for you
float rset=120, r;

println("use key [p] for sysinfo, [n] numinfo, \n[s] stresstest ( "+grid+"*"+grid+" = "+many+" ) points, [+][-] grid +-5" );
}
void draw() {
surface.setTitle("SYS INFO "+ nf(r, 0, 1)+" FPS" );
if ( stressenable ) stress();
r = frameRate;
if ( r > 30 ) stroke(0, 200, 0);

i see 40 FPS on a RPI 3B+
++ without stress : key [s] 118 FPS
the RPI4B-4GB (60euro) should be faster as my 3B+,
BUT NOT 10 times slower as a 600euro desktop
but yes, big canvas/fullscreen is to avoid for dynamic applications.
