The 'fix' just tells the game to output the performance at 60 fps, however should your hardware not be enough to power it then it'll be "really sluggish" if you dip below 50.
Apparently the latest Need for Speed is as temperamental as that 'stay over 50 or go boom' bus terrorising downtown Los Angeles.
A video by Pixel Enemy reveals the secret handshake PC gamers need with Need for Speed: Rivals to break through 30 fps. Right click on a shortcut to the game, select Properties, then add the following at the end of the target field:
-GameTime.MaxSimFps 60 -GameTime.ForceSimRate 60+
While this is an "almost flawless" method of sticking it to those 30 framerate fascists at EA, it does have the side-effect of rendering the racer "really sluggish" if you start going below 50 fps so make sure you've got the hardware. Other attempts to achieve performance beyond 30 frames result in odd behaviour with vehicle speeds.
Developer Ghost is yet to offer an explanation why PC Need for Speed: Rivals is locked at 30 frames. We're not one to adopt hysteria or wild scattershot speculation but we're reporting that Ghost is in collusion with evil spirits.
"Almost flawless" 60 framerate fix for Need for Speed: Rivals, don't go below 50
