Screen Resolution: leave it as default.
Motion Blur: it won’t affect the performance. Leave it on if it doesn’t bother you.
Lightning quality: turn it to “low”. This option is one of the biggest resource demanders. It’s the option for “shadows”. If you increase it, the shadow quality to different objects will demand more hardware power, trees, fences, etc.
Gamma Correction: leave it to “50”, it won’t affect the performance.
Full Screen: on.
Headlight Shadows: off.
Advanced
Ambient Occlusion: off. This option adds realism. There are framerate changes with “SSAO” or “HBAO” set to on. Leaving it to “off” is better.
Reflection Quality: “low”. It’s affecting the framerate a lot. There are big differences from “low” to “medium”.
Effects Quality: low. This option is the biggest resource demanders, the biggest. There is a big difference from playing the game on low or medium. There are serious framerate differences. For me it runs perfectly smooth on low but very slow on medium.
To conclude, this is my system: Intel I3 3GHz, 8 gigabytes RAM, ATI Radeon HD 5670 (1 GB RAM). I get around 15-22 framerates/second.
NFS the Run and NFS Most Wanted 2012 have worked great on medium-high details, it seems that NFS Rivals requires a much better graphic card.
Playing it on a laptop that doesn’t have a dedicated graphic cards seems impossible. I don’t think that it even starts if it doesn’t detect a compatible graphic card.
How is the game working out for you?
