This is something both AMD and Nvidia have had years to get used to and work with. Where DirectX 12 and Vulkan both chiefly rely on the game engine to handle all of the heavy-lifting, older APIs mostly apply pressure to the GPU driver. The problem is that DirectX 11 and 9 as well as other older APIs are much different from DX12 and Vulkan. Plenty of older (and not even that much older) titles still rely on DirectX 11 or even older versions, and gamers are right to expect that they’ll be able to play these titles on their modern-day rig, too. While it’s a good thing that Intel Arc is so well optimized for DirectX 12, which means it will run some AAA titles with relative ease, a graphics card can’t only be used for the latest games. There’s no way to sugar coat this - this can be a problem. In the video, Linus noted that going from DX12 to DX11 resulted in a 45% performance drop in Shadow of the Tomb Raider. The topic of DirectX 12 and Vulkan versus DirectX 11 first came up in a recent Linus Tech Tips video that both Shrout and Petersen also took part in.

While we still didn’t get any of the (perhaps even more pressing) juicy news, such as a release date, we’re slowly getting to learn more about the performance of Intel Arc. Intel shared a quick Q&A video with Ryan Shrout and Tom Petersen, in which both the experts give an honest update on the state of things for the graphics card. Will gamers even entertain trying out Intel Arc with these issues in mind?

On the other hand, AMD and Nvidia generally don’t share those problems. The video makes it clear that optimizing Intel Arc for DirectX 11 and older is still very much a work in progress that might never come to an end. Intel Arc Graphics | Intel Arc Graphics Q&A - Legacy & Newer APIs
