Hello. I've been trying to solve this problem for months now, so if anyone can offer ANY advice it would be GREATLY appreciated. When I run Xsplit to stream my screen to Twitch.tv, the framerate drops greatly in League of Legends when there is action going on the screen, whether it is the big team battles or just the minions fighting each other at the beginning of the game. I've experienced framerate drops down to 25 FPS while pushing towers when the default framerate when nothing going on is around 70 FPS.

I run Windows 7 Professional via BOOTCAMP on a Apple Macbook Pro (Early 2011). These are the specs:

ATI Raedon 6750M
8 GB RAM
Intel Core i7 2820QM @ 2.30GHz (Sandy Bridge 32nm Technology)
1680 x 1050 Screen

I have a 30 Mbps download rate and .97 Mbps upload rate, which is fine, because I stream my 1680x1050 stream at 900x600 at 350 Kbps (pretty low quality). I don't think my internet connection is the problem.

This problem has occured with the stock BOOTCAMP graphics drivers for the ATI 6750M. I've tried downloading the latest modded drivers as well from the following website, but the same problem STILL occurs:

-When I start the task manager while streaming, it shows that I am only using 30-50% CPU Usage.
-It does not make a difference whether it is on "Full Screen" or "Borderless" mode. The framerate is still very high when there is no action on the screen. As soon as the action starts, it plunges dramatically.
-The framerate HAS THE SAME DROP in performance during action sequences whether I set the graphical settings to LOW or VERY HIGH. (In other words, the framerate will drop from 85 FPS to 25 FPS whether the graphics card has to work hard rendering visuals or not). This leads me to believe that it is not a graphics card problem.
-I've tried using Dxtory to record my screen and XSplit to broadcast, but the SAME problem occurs: ( http://www.teamliquid.net/forum/viewmessage.php?topic_id=272764 ).
-I've tried lowering the streaming FPS to a meager 12 FPS but the SAME problem occurs.
-I've tried lowering the screen region to be streamed, but the SAME problem occurs: (ALth0r's response on this thread: http://www.xsplit.com/forum/viewtopic.php?f=13&t=2090 )
-I've tried streaming via command prompt with Adobe Flash media encoder 2.5 and 3.2, but the SAME problem occurs: ( http://root-destiny.com/newbies-guide-to-streaming/ )

If you would like to know any more information about anything, PLEASE ask.

Again, any other ideas to make this work would be greatly appreciated! I don't care if I have to lower the settings of my stream even more, I just want to be able to stream without it affecting the FPS of my game! Thank you in advance for any responses.
