Has anyone else noticed this? It’s perfect through the composite. When connected to an LCD via HDMI. I get a slight delay when jumping while, for example, playing Sonic. I actually have this same problem with the Xbox 360 version also.
I’ve heard that HDMI adds a slight delay but in my opinion it’s not worth talkng about, I have my pi in a 2 step HDMI solution (pi-receiver-TV) and I still haven’t noticed any lag. Many modern TVs have a “game mode” though, a mode where all picture enhancements etc are turned off to get better response time. You should check if your LCD TV/screen have that and if it’s activated.
