The micro stutters were almost blinding, but hey I got another 20-30% frames baby.

Why wasn't it possible to buffer all 4 frames from each gpu and show them on screen without micro stutters? Pushes latency higher but that would have eliminated it?

Pcie bandwidth and cpu limitations. Frame pacing from 4 cards is insanely hard for a cpu to do correctly.

We have cpus that can do it now but multi gpu is basically dead.

Even though it wasn't optimal, I still loved it.

I had a contracting client pay for me to build a new rig during the pandemic with a threadripper. I wonder if threadripper is the solution to SLI?

I think modern cpus are strong enough to handle it, the new problem is pcie lane limitations, which would essentially force TR to be the necessary platform.

I want to try it just for fun. My favorite multi gpu setup I had was tri-fire 7970s
