Something like over clocking. This article from ZKG seems too outlandish to be true, but if you can over clock a CPU, why not a Blu-ray drive? The premise of the article is that Call of Duty: World at War can destroy the PS3’s Blu-ray lens.
“They [a former employee of Infinity Ward] said that the way that Treyarch’s code is executed and organized causes the disc to spin too fast in the PS3 thus blowing the Blu Ray lens and that is what causes all those disc read errors.”
The article is well written, informative, and worth a read. For a few minutes I started to wonder if one of my PS3 games f’up my lens, but then I remember that the toddler stuffed in three discs. Same results, different article.
