be it a higher resolution or an equal one. if your PC has a decent amount more processing power/a fairly notably more powerful gfx card, be it in crowded areas or generic run from A to B, the game should have a better performance (smoothness, graphics, feel, fps) i will admit that were your pc is only a tiny bit more powerful the PS3 may win in performance due to it being a console designed for gaming, but in terms of potential a PC will always trump a console.
on the topic of resolutions, there is a reason beyond the graphical side for having larger resolutions. HUDs for games are, almost always, at a preset amount of pixels, so the larger the resolution, the smaller the HUD and so the more of your screen that is free to view the wonders of the game/overlay over stuff on. Personally i can notice the differences between 1080, 1600, 1900 resolutions and where possible i will always go for the larger, gives more room to play with, and in terms of your mouse, a larger a resolution allows better use of high dpi mice due to the larger desktop surface to cover :)
A non-gaming rig won't beat the PS3 at launch. A few years down the road, that's a different matter. The PS2 had no problems at all with frame rate during normal situations. It was only when you were camping Faf, Dynamis, Campaign, and those sort of things did the PS2 lag. We don't know how the PS3 will react yet in FFXIV. However, SE's history on the PC is less than stellar. So if we go by the numbers, it's safe to say that the PS3 version is more likely to run better out of the box.
A higher resolution might be great for some games like Starcraft, but I don't believe you'll benefit from a higher than 1080 resolution in terms of control in FFXIV. Sure the graphics will be slightly better, but it's barely noticeable. All the screen shots are taken from the PS3 so far. I think it's safe to say SE has learned a thing or two about creating MMO's on consoles. Back when FFXI came out, the graphics were a huge step down from FFX. On the other hand, FFXIII and FFXIV look very similar. That's relevant because most of the PS2 players myself included that switched to PC did so because of the enhanced graphics and less lag.(Dynamis)
We both know this isn't about pixels and PC interface. The people who prefer the PC version aren't being honest. This is really about modifications to the game itself. Don't like the music track, swap in your own stuff. Tired of a looking the same, swap your .dat model with something else. The bottom line is most people that want the PC version so they can cheat/modify the game. No matter how much effort SE includes to allow customization, players won't be satisfied. Every single time any problem is addressed in these forums, someone will chime in with the Windower cheat. If you ***** about DD's who blink too much, get Blinkmenot. If you're tired of RMT spam /tells, get Chatmon. If you're too lazy to quest a map, just get AP radar with map packs. Edited, Jan 7th 2010 4:30am by ShadowedgeFFXI
