I have installed 181.22 version of Vista's 32 bit drivers and K-Lite's Mega Codec pack v220.127.116.11.
Whenever I play any video using Winamp or any player that uses DShow, I get abnormally huge CPU usage which was not the case in either XP or Vista.
Heres the results from playback of two file types:
1. an AVI file:
2. an RMVB file using the Real Alternative installed with K-Lite Mega Codec pack.
It feels as though my GPU is sleeping and letting the CPU do all the work!
Thanks for your time!
