SLI not working properly

Hey everyone,

I tested my two EVGA GTX 970 SC ACX 2.0 with some games and seems they are not working fine or something.
They are both connected with the EVGA 2-way bridge (the rigid one, not the PRO or the flexible). One of them is in the primary PCI-e slot and the other one is in the second one (the 1st after the primary slot).

Ryse: Son of Rome everything high/very high 1080p with AA etc. is giving me 20-25 FPS in scenarios with lots of water, reflections and lighting. I saw videos in YouTube showing people with almost my same rig with better FPS than that.
GTA V is giving me 30-50 FPS in places with lots of vegetation and that stuff. There's a Guru3D benchmark showing like 100 FPS with 970 2-way SLI.

Any ideas? Am I doing something wrong?
