hey guys,

i want to stream world of warcraft @720p, the quality is very good and twitch gives me an "excellent" stream quality.

the problem is my system so i got extremly fps drops in wow from ~70-80 to 12-15 when i start the stream.

system:

intel i5 750
geforce 460 gtx
4 gig ram

100 mbit down 6 mbit up connection

is it possible to stream without having those fps drops?

here is the log file:

thanks!
 
Hm, I'm slightly worried about that amount of RAM, in the log it says you only have 900 free when you start up the program. WoW can use a lot of RAM. The CPU is a little older but it's 4-core. Everything else in the log looks fine though, couldn't really say for sure why it's happening.
