this is a great engine; it's practically the next-gen source engine. it runs fantastic on the xbox360 and as we can see here, is very good with "older" systems. can't knock the dunia engine one bit, it's great

I might not have a quad core processor or over clocked machine but 6 gigs of RAM has to count for something here ..............it absolutely does NOT and if you don't know that you need a lesson on gaming hardware
