First: You wrote this thread in the wrong place in the forums. General discussions is over here: https://steamhost.cn/steamcommunity_com/app/621060/discussions/0/

Secondly: You also need a power supply that has enough physical (either two 2 sets of 8-pin plugs, or two sets of 6+8 pin plugs. If you have a smaller power supply it likely doesn't have enough plugs to connect to the video cards.

Also: You want to use two *IDENTICAL* video cards in the game. Not just an MSI GTX 1070 and a EVGA GTX 1070, two MSI GTX 1070's for example or two EVGA GTX 1070's, preferably of the same model. If you have mismatched video cards then you will have to match the clocks using the GPU overclocking tool.

And lastly: Not all Nvidia video cards even support SLI at all in the first place. Only the GTX 1070 through 1080 Ti for the 10-series, the RTX 2070 Super (NOT the RTX 2070) upwards through the RTX 2080 Ti for the 20-series, and only the RTX 3090 for the RTX 30-series. You must use one of these models for Nvidia's SLI to work.

Hey. Thanks for the reply.
Yup. I got two identical SLI able MSI GeForce GTX960. Maybe I need to go higher?
Plus a 600W Shean PWS. I thought it might have something to do with the mother board and the BIOS but no go.

Which motherboard are you attempting to use? I'll look into it for you in a bit when I get time.

Don't worry about me. I'll figure this out another day. I'm going to bed (real life).
But thank you very much.
