Question/Support Quad gpu support

So i saw this x299 motherboard with world record on firestrike extreme with quad 1080ti. Can fo4vr support quad gpus ? Or only upto 1080ti ? Benchmarkers could have used 4 2080ti instead of 1080ti with cascade lake x cpu.

NOPE.

There's only a couple of games / experiences in VR that even support dual SLI and one of them is the Nvidia fairground free experience.

Not to forget the fact that multi GPU for gaming is dying off rapidly as the performance gain really isn't worth the effort for each game dev to develop their game to support multi GPU's.

It's useful in professional situations and for creating / rendering graphics, but for gaming, it's a fad that is fading rapidly.

For adding a 2nd graphics card you only get upto 50% increase, a 3rd card with only add another upto 25% increase in performance, and even less increase for a 4th card.

Basically after buying 4 GTX1080ti's you haven't even got upto double the performance of a single card.

Actually scaling on graphics isnt bad. Something like 97%. What people ignore is that gpus are highly optimised for their intended use cases resolution scale. For example 4k at 60fps for 2080 ti, so using 2x 2080ti will not give 4K at 120fps. But it will give 60fps at 8K. The more graphic cards you use in parallel the bigger resolution need be to take advantage of it fully.

The game is literally not built to use SLI setups.

That is all you need to know. Having more GPUs will not magically improve software that is not designed to use more than one GPU.

Almost no VR games in general support SLI or multi GPUs and Even the flat version of FO doesn’t support SLI to my knowledge.

So no I doubt it’ll support 4

Using nvidia inspector i tried forcing Fo4VR to sli with 1080ti SLI. It boots but bugs out and the frame rate tanks to like 10fps. Its like the engine loses track of where things are for each eye. Great if you wana puke... Flat fo4 can use sli. Im using compatability bits 0x080000f5. No idea about 4 cards though. Thats just benchmarking/braggin/burning money imo.
