麻煩請提供來源，這邊提供幾個我查到的資訊：

1.Steam上奧德賽頁面，關於GPU更多細節的官方連結
https://support.ubi.com/en-US/Faqs/...yssey-ACOD/#GPU
The following features are not available in Assassin's Creed: Odyssey - SLI, Crossfire and Dolby Atmos.

2.https://www.performance-computer.co...graphics-cards/
Assassin’s Creed Odyssey does not have support for SLI so the GTX 1080 SLI benchmarks are not possible.

3.打臉SLI！雙顯卡效果超失望！RTX2080 NVlink慘不忍睹實測！

4.唯一查到在4K下SLI性能有提升的是 https://youtu.be/oSnsCzEkalQ
但很怪的是1440P、1080P下又變成SLI比單卡慢，沒看過單款遊戲會有這種現象

連底下留言都說
Pengyu He:
Some of your benchmark results seem way off.
For example, AC: Odyssey does not officially support sli,
yet your benchmark result shows 12 fps gains using sli in 4K.

Blazer 6905:
Yeah agree

Kelstr:
I don't understand where he gets the values for... for SLI in AC: Odyssey?!?!?!
I had two 1080 ti's and couldn't get them to work in that game.
Now I have one 2080 ti... and I would love to buy another.... IF AC: Odyssey supports SLI.

故推測此影片的奧德賽4K SLI分數有問題
