    I'm really excited about 3D audio hardware. BFV only plays 20 sounds at the same time, but PlayStation 5 will be able to play over 100 sounds at once.

    The SSD speeds and custom hardware built into PlayStation 5 to offload data decompression is impressive. Mark Cerny said it would take 7 AMD Zen2 CPU cores to process 5GB/s of SSD data if there wasn't custom hardware to offload the work.

    Makes me wonder how PC's are going to be able to play next-gen games. I'm sure PC CPU's will eventually come out which have the same hardware blocks built-in for data decompression like the PlayStation 5 and Xbox Series X. But none of the current PC CPUs have such features.

    I'm not a fan of Sony's approach for CPU and GPU boost frequencies though. This means as the workload goes up, frequencies go down. I like Microsoft's fixed frequency approach much better.

    I'm still on the fence as to which console I'll buy. I'm leaning toward Xbox but PlayStation usually has a better game selection.

    I just want kbm support. I hate using gamepads for shooters.
