The xbox version ran on CryEngine 3 compared with CryEngine 2 on the PC. Huge efficiency gains there by all accounts.
Yeah, the PS360 need a heavily threaded engine to perform comparably to a dual core, dual thread PC CPU from the late 'noughties'. That certainly wasn't Cryengine 2! It couldn't even max out two threads on two cores.
This is only relevant in PC only games. If you are writing a PC only game and want the largest audience, you need to target a much lower base spec.
Yeah, I was talking about PC exclusives from around the time of the PS360 launch and, I guess, around the DC, PS2 and Xbox launches. Despite the raw power of high end PC gamer systems, PC exclusives couldn't afford to target only the console beating stuff. Crysis tried, but it's horrible inefficiency (despite the bullshit claims about amazing quad core support) has kind of muddied the waters regarding just how demanding it was vs how cutting edge it was.
Cross-platform titles don't have that issue, and that's the future for PC games. If you're writing a PC game, target the consoles as well and have them as your minimum spec. There isn't going to be a case where the PC target is lower than the console spec and high-end PCs are going massively underutilised.
Not now, but when the PS360 came out they were well ahead of the curve for most gamer systems. If next gen consoles can use some kind of unavailable-in-PCs APU based acceleration there may be a lot of lower end PCs excluded by minimum specs. If you can remember the amount of butthurt when PC minimum specs for games like Assassins Creed and GTA were released, and the even higher specs required to match or exceed the console experience, you can expect some angst in 2014. I don't expect it to be as bad as it was in 2006/2007 though, due the advancement in PC integrated graphics and the sheer power of PC gamer CPUs.
