Considering I just got the card on Friday, I am running the 2F16 update on my card, and I am running on a Cable internet connection. My latency is fine, thats not an issue at all. I think WoW is retarded and doesn't wanted to use all 8 cores or anything, because this is making me mad, I upgraded my system from a Single 3.0GHz Quad Core (2006) with an HD3870 ATI card, to 2 x 2.26GHz Octo Core (2009) with this GTX285 Mac Edition card and am noticing an increase in performance everywhere except in raids and dalaran... Is 6GB of Ram going to be good enough to have good FPS in raids or do I need more? I have heard that due to my lower clock speed on my processor its what is limiting me atm... which pisses me off because my old machine was on its last legs and still under warranty and needed an upgrade, so I went with the 2.26 Octocore because it was most affordable and seemed a little more future proof vs just getting another new quad core nehalem or not.
Ok, internet isn't a problem then.
The lower clock speed shouldn't make you that slow, on an individual thread basis you are about 10-15% slower then me, so you should only me 1-3FPS slower then me, not 10-20...
My WoW client does farm itself out over multiple cores with the mask setting (my 85 puts it on the primary thread of every core in my 4-core machine)... You saw no difference between 255 and the default?
6gb should be plenty, I have 8gb... What else are you leaving open when you play?
Apparently most people are still pointing to driver issues at the moment:
"Where the drivers really fall apart is 3D performance. The GTX 285 has three operating states or power consumption modes. Under windows, the drivers are intelligent and work properly with the hardware to ramp up the speed of the GPU and onboard memory when needed. On OSX, the card only wants to ramp up occasionally and it seems only with certain CUDA functions. So the problem with the card is that it's typically stuck operating at it's slowest speed when in OSX. It could also be an EFI issue. The BIOS obviously works fine as the card performs properly under Windows. However, the problem under OSX is most certainly driver, and possibly EFI, related. I remain hopeful that it will be fixed. It's being discussed at Macrumors, Macforums, Apple forums and the EVGA community. Everyone is bitching about it. The current work-around is to load a small CUDA demo app that will kick the GPU into high gear and then leave that running while running an app that we want to benefit from the faster GPU settings."
Try doing that thing with loading a small CUDA app while going to go play WoW.
Try turning off shadows for now....
