Question / Help Redicolous FPS drop

Hi,

I have been able to broadcast in 360p at 60fps without any lag before but when I tried yesterday it even lagged at 160p, I had to push it down to 20fps to not lag.
I'm using the normal settings other than that so it makes no sense.
Why is this happening?

Sorry for the late response, totally forgot about this thread haha.
This only happens when I try to window capture AmarecTV it seems like (Even AmaRec drops its fps).

Not entirely sure, but I can say that the CPU is particularly weak, lots of duplicated frames as well. If you're using window capture, I would advise making sure aero is *on* as well to prevent it from increasing CPU usage (it'll be on only when the glass theme is active in windows)

Thanks for the reply,

Aero definately boosts the capture performance, only bad thing is that I can't capture the game.

It works without Aero but the fps drops ridiculously.
It has worked until like two months ago so I don't know what's wrong.
I'm going to try to install an older version of amarec and see what happens.
//EDIT
Older version still same issue, this is really strange why it doesn't work.
