How much memory/CPU time does AVR use?
AVR uses quite a bit of both memory and CPU. CPU time is the more significant of these as using a lot of memory doesn’t in itself really affect game performance all that much. Also this depends very much on the complexity of currently visible markings. One thing to note about CPU usage is that AVR uses the more CPU the higher your frame rate is. If your normal frame rate is 120 then you might very well see a significant drop, maybe upto 10 or 20 fps less. If your normal frame rate is 20 then you’ll see a much smaller drop, probably not even 1 fps less.
