Ok, so on DAS forum a friend of mines asked that question. And alot of people had the same problem so yea thought i share, if your vegas is lagging while ur like editing, highlight the part tht u want to watch or edit, then press shit + b it will play it by itself but without sound. Its normal. After its done, replay the part u want to see and THERE! IT DNT LAG <3 HOPE THIS HELPED
