Can someone explain why I should care about input lag speed on a golf sim projector? I'm using a skytrak so I know there is a delay compared to other LM's but even if I wasn't it seems like this feature only matters for PC gaming with a controller. Am I missing something? It seems like I can get more bang for my buck on a short throw in the "conference room" class vs "gaming" class of projector. Or is the refresh rate the real difference?
