If you decide to buy Intel’s upcoming Arc graphics cards, brace yourself for some mediocre performance when it comes to running older PC games.

On Thursday, Intel admitted the Arc GPUs will struggle to produce high frame rates for some PC titles built with the older DirectX11 and DirectX9 APIs from Microsoft. "On Some DX11 titles, we’re going to do great, but other DX 11 titles are not going to do great,” Intel Graphics Fellow Tom Petersen says in a video the company posted(Opens in a new window) on Thursday.

The reason is due to the older DirectX11 API relying on Microsoft and the GPU driver to handle the game's memory management.

According to Petersen, Intel essentially still needs time to optimize its graphics cards with a variety of older games that were originally designed with GPU hardware from Nvidia and AMD in mind.  “We have to do a really good job of behavior that the game developers have come to expect when they’re using Nvidia hardware,” Petersen adds. “The truth is our card works very differently from Nvidia, so we now kind of have to start tuning all of our DX11 work to match what older titles have expected.” On the plus side, Intel says the Arc GPUs have been optimized for games running on the newer DirectX12 and Vulcan APIs, both of which originally arrived about seven years ago.
