Re: Can Geforce GTX 880M SLI run the game on (mostly) Ultra?
Unfortunately, straight off the bat with using mobile GPUs, and whilst they've come on leaps and bounds, you're utilizing shared system RAM so in terms of speed and efficiency you're down from native DDR5 VRAM.
I run the game on a tower, on Ultra with post-process and AA tuned down, just to make sure I sit under my 780 SC ACX SLI 3GB VRAM cap and by being 10% comfortably underneath, with all my rig running on high performance SSDs, OS/Pagefile/game separated, with 32GB of 1866 RAM, the game runs awfully. The tutorial boss fight was unmanagable, through a combination of bad controls, no tactical view worth a damn and chugging performance.
So sadly I'd have to agree that you'd be looking at a fairly hefty reduction in fidelity in order to get something playable, though obviously that can vary from person to person. My threshold is fairly low.
Maybe Bioware can further optimize, with help from Nvidia but basically its completely out of our hands right now. Fingers crossed time.
