I had just 1 question...but as I started typing this...I decided to a couple others... #1 - I play a scenario from the Creation & Customization forum - Lokolus' Earth 1862. IF I want to delete the airship unit from the entire scenario, how would I go about that in XML? I check the scenario XML and there are no units...so - I am guessing that means I have to delete it in the actual Civ4 BTS XML (since this is a scenario, and not a mod with its own XML)? Also, when I go into the XML to delete the airship...what exactly should I delete? The entire coding for it...or is there a more simple way to turn it off (switching a 1 to a 0 for example...or making it obsolete at a tech far, far in the past??? #2 - *This is much more random* - My computer is a Sony Vaio (desktop), and is Pentium 4, 2.53 GHz with and it has 512 MB RAM. I run a Geforce 6200 graphics card. I get a LOTTTT of lag late-game (1 minute+), and it generally crashes due to low virtual memory even though I play on the low-resolution visual settings. My question is...would I be best served to purchase more RAM (if so...up to 2 GB, 3 GB, 4 GB??), or is this a problem of my 6200 series graphics card and would it be better (obviously better, but NECESSARY) to get a 8500 series graphics card? Or is it both?... Meaning...IF I got the RAM up to whatever is suggested...will the game stop lagging if I kept my 6200 series graphics card? Or do I NEED to get both? PS: Im MUCH, MUCH more interested in simply having game-speed late game sped up, Im not overly concerned with using the high-resolution graphics settings (if that matters at all).
