I don't even know what to think about the strange gap between the Nvidia and AMD graphics card requirements. I have a GTX 660, which easily outperforms the GTX 550 ti that is listed as a minimum req for Nvidia. This implies I should be in pretty good shape. But, the GTX 660 is comparable to the 7870 listed as bare minimum on the AMD side, which suggests that I may be scraping the bottom of the barrel performance-wise.
Is the game particularly unfriendly to older AMD cards or better optimized for older Nvidia ones? If so I'm probably in pretty good shape.
Are the reqs wrong? If so, which? If the listed Nvidia card is wrong then my rig may end up struggling if the actual required card is more powerful. I hope that's not the case.
On the other hand, the Radeon 7870M is more http://gpuboss.com/gpus/Radeon-HD-7870M-vs-GeForce-GTX-550-Ti to the Nvidia 550 ti. Could they have left the 'M' off the system req listing? That would be a good thing, but the 7870M looks far too weak in certain areas.
Even knowing the reqs I'm not quite sure where my system stands with this game.
EDIT: I notice that while the 7870 tends to blow away the GTX 550 ti in most tests, the 550 severely http://gpuboss.com/gpus/Radeon-HD-7870-vs-GeForce-GTX-550-Ti the 7870 on the 3DMark 11 test. Could it be that the older AMD cards had issues with DirectX 11?
