My loading time wasn't faster than my teammates, and seeing as I'm the only one recording and I'd have to be the first to load in, we decided to host local. When we got in my FPS was dipping over 100 FPS and my gameplay and video were both laggy and unbearable. Any tips on how to fix this?

I really want to start speedrunning on Left 4 Dead 2 but I can't seem to be able to put a timer over my video, yes I'm stupid -.-. Am I forced to put a timer over my video or can I submit it without any timer at all, I've heard I won't be allowed because Moderators would have to manually take away the loading times but I need to know.
