This means any malicious software on the system can poke a dodgy driver installed by SFV to completely take over the Windows machine. Capcom claims it uses the driver to stop players from hacking the high-def beat 'em up to cheat. Unfortunately, the code is so badly designed, it opens up a full-blown local backdoor. Gamers realized something was a little off when the upgrade brought in a new driver and demanded operating-system-grade access to the computer before the game starts. A number of players say they couldn't even get the new version to work at all. A full-blown online meltdown ensued.
