Support SLI / Crossfire (Red Dead Redemption 2)

in theory, you can try under Windows 10
installing NVIDIA force drivers if the drivers have not been updated and there is no game in its registry if compatible
and under earlier Windows API and cross fire probably did

Does not work on Windows 10. Profile in Nvidia Inspector has a profile RDR2, but nothing works. Firewood last - 441.12

The game uses the new API, which support Multi-GPU developer has to implement himself. If he did not, in any way.
