Well I disabled all the nVidia stuff on my old PC (filtering, smoothening and whatnot), put 16bit color depth instead of 32bit, and selected "disable windows theme" on this game's .exe properties and now the game runs absolutely fine.
Just to mention, my PC is Duo Core, 2.0ghz, 3g Ram, Windows XP pack 3 and a graphic card I bought back in 2007 Runs perfectly fine, I can't understand how the newer and more powerful PCs some of the people here have can't run the game…
Scrub Mentality: When you lose, its either: Lag, Opponent Character is Broken, Spam. Remember, it is never your own damn fault
Whats truly pathetic is that this has easily been discussed 15 times here, if not more, in the month the game has been out and people like you saying "upgrade your machines" can't wrap your tiny brains around the fact that games made with Game Maker aren't compatible with every processor. S***, try and pay attention, even Capcom themselves acknowledged this when they announced v2.
