Help I got the game and cant get it to work above 1600*900 at any aspect ratio...anyone else having this issue ?
add "-norestrictions" to your shortcut command line. Keep in mind you have to have RGSC already running for it to work, and hitting the 'Play' button on RGSC window won't enable it. So from scratch, yo ahve to run it twice. Once to start RGSC andn again to start the game.
Pretty stupid, but it works. You should now be able to choose any resolution you monitor can handle. This settings also will let you select "high:" texture, if you cun't already.
Oh and you have to logged in to RSGC as well.
there are more commands on page 2 or 3 of the "GTA and more and more" thread.
