Batman with no physx on my 5870 = 60+ constant and still only 34% GPU usage, with full physx which consists of a bit of toilet paper floating around drops my FPS to 15 and still with only 34% GPU usage, all these crap effects could easily be done on the CPU or the single GPU and still have max FPS, NV you are scum.
I agree, though I do partially blame AMD. They should have gotten their "TWIMTBP" program off the ground sooner, otherwise known as the, throw money at people to make them your friends program. But AMD really couldn't afford it, for the last year they should have been courting companies and giving more support(IE money) to dev's to counter Nvidia as their rich oil buddies can certainly afford to.
Or they could have long ago taken the moral high ground and really should have started legal matters over anti-competitive practices. I'd prefer the later, but could live with the former(begrudgingly) however they've done neither which is a bit of a dropping the ball situation. The problem being, even if they couldn't win the court case, bringing it to light and having people investigate Nvidia would at the very least, scare them into behaving, best case scenario is every developer stands up in court and said, yeah, we'll pay you to screw AMD, if you don't go along with it, we'll make your game crash on our hardware, you never know. It was a win-win situation for AMD though.
You really shouldn't have to offer say, the Batman makers money aswell as personel just to get them to not screw you. Nvidia make noise about lack of support AMD give, but I'm fairly sure the help to dev's is there should they want it, offered willingly infact, but when one side pays you and one doesn't, things get unfair fast and prefential treatment couldn't be more obvious.
What is a little funny is, no matter how many games have Intel inside logo's, theres never a difference in performance between games on Intel vs AMD, ok games are gpu limited. However Intel, despite their money and support, haven't ever, afaik, had anyone cripple a game when working on an AMD cpu.
So Nvidia, its possible to pay money, support companies, help them optimise without the backstabbing, sabotage and unsportsman like conduct. Intel have the money to buy Nvidia, shut them down and blow up every asset they have(which isn't much) without batting an eyelid, yet they never sabotaged AMD in terms of software and support.
