No, Doom 1993 does not support SLI or crossfire.
Doom 1993 doesn't support SLI or crossfire. You're right, it can feel like you're asking for a lot of power when you only have one GPU.
It does not.
None has come before a technology to back it up.
At the time of its release, the hardware intended for Doom lacked a modern GPU, let alone two.
Ohhh, ok thanks everybody for the responses!
And I realize my "PC master race" comes across as awkward.
It's a mark. It doesn't target you personally.
Great! I see you're just starting out here. Welcome!
All good.
I don't get it. Doom 1993 will run on an SNES--let alone a smartphone. WTF are you wanting to use SLI?
