One change in Firmware 3.50 that Sony failed to mention was that the PSP now uses the full power of the CPU. Previous firmware versions limited the CPU speeds to 266MHz – roughly 80 per cent of the portable console’s full power. But now, the PSP using Firmware 3.50 runs games at 333MHz, utilizing 100 percent of the CPU power. What does this mean? Faster game loading and possible better graphics for future games, but shorter battery life.
To those who use Dark_AleX’s OE Firmwares, 333MHz CPU speeds have been available for some time now so this really isn’t good news. The company has yet to give an official statement on this new feature, and whether this unlocked CPU speed is dedicated to post-3.50 UMD games, or will affect past titles as well. Maybe even a new battery is in the works to makeup for the extra power usage.
