你这说法我不同意，纯粹是Topaz Video AI的问题
这个软件还没更名之前，多GPU功能是这样描述的 (来自官方)
https://support.topazlabs.com/ar ... deo-enhance-ai#2gpu
My machine has more than one Nvidia GPU, can I use all of them?
Yes, you can use the Experimental All GPU option.
The Experimental All GPU setting is intended for users with multiple similar Nvidia or AMD GPUs installed (it will not work for Intel GPUs). For example, if you have two NVidia RTX 2080 cards installed or one GTX 1070 and one RTX 2080, this setting is for you. If you have a dedicated GPU and an integrated Intel GPU, you should choose your dedicated GPU, the All GPUs setting may not work for you or perform more slowly.
To enable both graphics cards you would want to select Preferences from the Video Enhance AI menu and change the AI Processor to All GPUs.
VEAI can only use 8-1 2 GB of VRAM in one instance, and can’t consume more than this at this time, you can launch VEAI again on a windows machine and that will allow the second instance to consume more.
We are working on optimizations to use all ram
这是官方的最低硬件需求：
https://docs.topazlabs.com/video-ai/system-requirements
官方有只说明了可以调用所有GPU
但是如果是使用A+N，或是同A、同N但是架构不一样的显卡 (例如1080+3090)，也没有说明是否可以充分使用
我自己测试单卡6900XT 和 6900XT+VegaFE，前者的速度还比较快，多了张VegaFE还扯后腿
而且最JB扯蛋的是，撇开不谈显存最低需要8G，A卡最低只要求北极星架构? N卡却要RTX3000以上?
而且官方ALL GPU模式下只能调用第二张A770，代表软件分不出谁是主副卡，且也证实了官方没有注意到有人会用两张Arc显卡来跑这软件
不拿线撕、蓝宝石激流等HDET平台相比，如果我用上Pro WS X570-ACE这块主板
可以实现3个PCIE4.0*8，意思是我去可以去收老腹肌588*3，但是能完整调用吗? 官方也不保证 |

持续关注中。。
独显核显都能deep link，做俩显卡应该没有啥难度
