1) Planetside 2 isn't a very demanding PC game. At least, not in the GPU sense... it is in the CPU sense, due to bad programming. It's not demanding so much as it is picky.
2) The titan while impressive, is actually pretty shit for it's price. In otherwords, a lot cheaper cards will do it close for less. Really, the Titan isn't actually needed for anything in gaming right now.
3) By better multi-core support they mean that Planeside 2 for PS4 will have better multicore support not that PS4 has better multicore support then PC.
Planetside 2 pretty much uses zero multi-threading and only uses one core on your PC. They were supposed to fix this WAY back in the beta days, but didn't.
Games now a days generally do support at least dual core... and a game like Planetside not supporting it, is generally a huge failure since it's putting 200 objects on screen at a time.
Generally, on a lot of computers it will run like crap... yet not use anything more then 30% of your systems resources... because they programmed it like it was for an old school single core computer.
or TLDR, PS2 will run better on the PS4 because it's programmers aren't so much "noobs" anymore, it doesn't really having anything to do with the PS4.
If they put the PS2 PC version on PS4 with the smallest amount of tweaks... it probably wouldn't even be playable... on any setting. PS2 runs like garbage on AMD hardware. Hence the need for a version with better multithreading.
It is a pretty fun game though. I'd definitly suggest playing it.
Hopefully they'll port the PS4 engine back over to the PC so people with modern PCs can run the game decently.
So PS4 development is forcing PC devs to have better multi-core support. I'd say that's a win/win situation.
They already said the work they're doing on the PS4 version will impact their PC version.
Most PC games already have better multi-core support.
PS4 is forcing one awful dev to fix their programming.
Meanwhile, if any dev doesn't have perfectly done multi-thread programming any multiplat game will run and look better on PC.
It's about as much a win-win as the Cell was a win-win situation. In that... it really wasn't, because it generally meant multiplats would only ever look worse... and in some cases could have some devestating problems. (Like Skyrim is a good example.)
It's not AS bad, since the PS3 is basically a fussy computer. That is still the problem though. Making multithreading perfect on an 8 core machine.
What exactly are you comparing to the Cell here?
The PS4 and well AMD CPU. The GPU isn't really an issue for most PC's and Planeside. It's a weird case where most of the time changing your graphics settings does NOTHING for framerate, because the bottleneck is in the CPU.
Basically the PS4 has 8 cores right? If the current Planetside 2 were to run on the PS4 and you did a core diagnostic, you'd find one core mostly worked... and the rest of the cores... hardly working at all. You'd probably be at about 30% of your resources used.
Whether your graphics were set to max or ultra low... your frame rate would likely be identical.
The same is true for most AMD CPUs. (Or the I7 really.)
Meanwhile CPU's with less, more powerful cores will run the game much much better.
CPU's with multiple cores will suffer due to devs who suck at multiple cores or just don't make the effort. Now a days usually games optimize for 2-4 cores. (Though again, planetside is bafflingly a 1 core optimzied game like it was the year 2000.)
AMD likes to use more cores to compete with more powerful Intel cores.
Ironically SOE has pretty much just ignored 8 core processorts making them one of the worst offenders.
The reason for the policy change i imagine is pretty obvious.
Hopefully, the trend continues in general, but really, we'll see. Plus you need to account for developers who aren't used to this suddenly having to do this. So don't be shocked if a bunch of the launch games are really kind of rocky like was the case with the PS3.
