| NJ5 said: @MikeB: Sorry to interrupt your self-quoting but aren't those seek times very different from what we've seen before? And again, why do so many multi-plat PS3 games require installation where the 360 versions don't? If the PS3's BD drive performance was so great in comparison to the 360, why would that happen? |
The Blu-Ray drive isn't so great with regard to transfer rate (it's similar on average, but there is better potential for data duplication, optimal usage and such, the speed is very competent though - all the content of a 25 GB disc can in theory be streamed in just 45 minutes), it's great with regard to storage capacity, drive noise, predictable streaming performance, etc.
Many multi-platform games have been assets wise optimised for the XBox 360 and optimised for DVD loading (CD/DVD have been used for decades, Blu-Ray is relatively very new technology). Optimising for Blu-Ray is different, this is where first parties with games like Uncharted and Killzone 2 set examples. On the PS3 you also have the default harddrive, using smart methods in game engines for harddrive caching you can take great advantage of this as well.
Like mentioned already, using the harddrive to install data is the easy method for multi-platform developers to overcome these differences cheaply and without too much effort.
