I have the battle size at max for native, and textures at 75

But good news! I had a couple (actually like 20) extremely suspicious files that have been deleted as of last night. That along with uninstalling Rome Total War and the couple mods that I had for it should give me the little extra speed I'm looking for. Before it would start getting choppy when lots of characters were on screen, just at random times, so I was curious to see how many viruses I had collected in the past month since I last checked.

So hopefully tonight I can bump up the texture detail a bit.
I'm pretty sure it's not yet, but just in case. Is the battle size changer ported to .90X yet?
