When you post threads, next time put more info in the title, lime what it's about. Makes it easier for people to search and find answers instead of asking the same questions over and over
While I'm thinking about it, make sure you do a LOT of reading BEFORE you ask questions.
Also... this is an engine comparison. You should have posted it in the Engine Comparison section, not the KA section.
Please glance over the layout of the forum post in the proper sections.
