Well, I have only 1 and it’s almost impossible to have some free time to get a good job done. The only thing I can do is 1 or 2 games for the 4k competition. I have started other projects, but they are never finished.
Anyway, I leave home at 7:30 a.m.; arrive at work at 8:00 a.m.; work work work and work; leave work at 5 p.m.; arrive home 6:30 p.m.; Then at home there are lots of tasks to be done: take a bath, eat, play with my kid and then when I look at the clock is almost midnight (time to sleep!). Repeat the previous loop 5 times: from Monday though Friday.
And in the weekend there is lot of noise at home, kids around, need to get into supermarket, wash the car, etc. etc. etc. 


Maybe anyone else knows? In good old home computer days you simply grabbed the vertical blank interrupt and render away on the backbuffer. You could even make simple performance measuring by swithcing the background color at start and end of your (assembler!) render code - good old days… sniff
