I have a GTX 690, and an Intel Core i7 2600K @4.4GHz. I put in the parameters in the shortcut target, and once I launch the game, it works for a minute or two, and then it starts stuttering. And the way it stutters is like the framerate is constantly switching between 60 and something else (faster or slower I don't know). I've tried everything: enabling and disabling vsync (adaptive, smooth, normal), triple buffering, and lowering the graphics settings. Unless someone (anyone!) would be kind enough to come up with a fix, the only way I'm ever getting past this needless problem is with an official patch.
