One of the big advantages of seeing the Xperia X10’s bootloader bypassed (apart from the ability to load custom ROMs) is the removal of the FPS cap that has been set by Sony Ericsson. We’ve attached an interesting video that shows this difference in action, where the user has two X10’s – one running on the Custom FreeKernel Alpha1 (i.e. cracked bootloader) and another on the Froyo CM 6.1.3 ROM.
He runs several benchmarks between the two and it’s interesting to note the difference in FPS rates in some (not all) of the benchies. Check it out below.
