That's interesting. What sort of "safe" are they trying to do? Do you know anywhere I could read more in depth about that?
I don't remember who did the analysis, but somebody disassembled the PhysX software driver and found that it used nothing but x87 floating point for the math. Considering that SSE has been supported since the Pentium III came out in 1999, that is inexcusable. I found a link to a story about this here:
http://techreport.com/discussions.x/19216It's just bullshit. The fact that NVIDIA no longer allows their video cards to act as PhysX processors when coupled with an ATI GPU is downright anti-consumer. Fortunately, OpenCL has been making some headway lately, because PhysX is too locked down for anyone's good.
Really? So I'm SOL as far as Arkham Asylum is concerned?
You might be able to get a speed boost by turning off PhysX, if the game allows you to do that. It should still play pretty well, you just might miss out on some physics engine effects (I think Arkham Asylum has extra details like papers fluttering around in the wind if you have PhysX enabled).
I'm also getting odd graphical errors in a few games I try (all lights in Amnesia can be seen through walls, and the AA looks off slightly. The wood that sticks out of walls in BC2 is untextured on some sides) so I'll probably delete all the odd drivers I have for ATI and then strictly install the CD drivers and then update them (I ran and installed a non XP pack I believe, a long with a bunch of other things).
Yeah, try reinstalling the drivers. The only game that I recall seeing rendering errors on lately is GTA4, but those are issues with the game itself -- the same issues occur on my dad's NVIDIA card (which is my old 9800GTX).
I'm assuming CCC is part of the default drivers.
Correct. I think it is considered an optional component, but it's installed by default.
