I'm trying to think of why the rubberbanding or lag that we're experiencing would be specific to de_piranesi, but I'm not coming up with anything. All I know is that when I get lag on this map, it's particularly severe. However, in general, most of my lag issues can be attributed to my ISP. I feel like there's input lag in every movement that I make. I wish that Google Fiber would get here sooner.
