I see it as they had the mantle driver portion of the driver ready but they've had many iterations of drivers in between. Now when BF4 is ready, they integrate the mantle portion and got some issues. They say installation issues, not driver issues, so that's what it appears more like to me...
That's the thing to understand. It's not giving the card MORE work to do, it's allowing the card to do a greater amount of work in the same time through optimizations. A pseudo example:
Pretend the card has to do this now:
1. Load texture A into buffer
2. Load a filter for use
3...
Wow. Very surprised at the troubles you had. Especially with the lack of troubles with the triple GPU tests you did. I would have thought mixing cards would give you troubles, not two of the same.
Say I wanted to use both sides of a circuit board. I have a 7-Segment LED on one and on the other an IC (not directly behind each other) so each component's pins were on opposite sides of the board. How would I connect the two?
The only thing I can think of is a solid wire going in a hole...
So what I take away from this is that Nvidia's drivers use the CPU more vs. ATI? That is really interesting. I'm wondering if they are doing some shaders (or post-processing on frames) in the driver/CPU vs. the GPU. Not saying that's necessarily wrong but just interesting on why they would...
MLAA + 5870 + Eyefinity = No. I have 3 x 24" monitors and 5870's in CF and it just doesn't have the power to run it. I think it runs out of memory. The 2GB on the 6000 series would come into play there, I believe.
