Intel Promises Improved DX11 & Legacy API Gaming Performance on Arc GPUs

Intel has confirmed that they will be bringing improved DX11 and Legacy API gaming performance to Arc GPUs in a recent video. The company admits that they are aware of poor gaming performance in titles using DirectX 11 and are working to improve the experience in the future.

Intel admits it’s fallen behind on older APIs, but promises to improve DX11 gaming performance as time goes on

Initially reported in a LinusTechTips review, the tech outlet witnessed a 50% GPU performance difference between DirectX 11 and 12 versions when comparing Shadow of the Tomb Raider on a system using the Arc A770 graphics card. In the previous version of DirectX, the game reached close to 38 FPS, while the latest version saw an increase of around 80 FPS.

DirectX 11 and earlier APIs work differently than the updated DirectX 12, Vulkan, and other current APIs. The older API technology requires most of the graphics driver processing, from enhancements to customizations made for low-performance cards. The need for the GPU to handle more of the game work was to ease some of the burdens on game developers looking to optimize the look and feel of their games.

With Vulkan and the current DX12 API, the boost is no longer dependent on the graphics driver but on the game’s graphics engine. Game developers must now handle the responsibility of graphics optimizations, especially on weaker systems, and place tasks within the game code to shoulder this burden. An example of this is video memory allocation.

Intel hasn’t had to worry about graphics APIs because they haven’t developed GPUs for many years. Now, with the company’s Arc-series graphics, they have to catch up with the companies that have focused on this type of technology for years, namely the company’s rivals AMD and NVIDIA.

This perception of the company’s ignorance of DirectX 11 and older APIs has led Intel to admit that it will take a long time to understand and find solutions to the issues affecting its current iGPUs and dGPUs. Intel colleague Tom Petersen has recently been quoted on the road to improving the API for Intel, stating that the issue will be a “forever labor of love”.

Most of these issues stemmed from the dependency on the integrated graphics software stack hosting a very different architecture compared to Arc GPUs. This resulted in inadequate performance levels, game/API compatibility, etc.

“Our software release on our discrete graphics clearly underperformed,” Gelsinger said. “We thought we would be able to take advantage of the integrated graphics software stack, and it was totally inadequate for the levels of performance, game compatibility, etc. that we needed. So we’re falling short of our goal of four million units in the discrete graphics space, even now that we’re catching up and getting better versions of software.”

“While we won’t hit our GPU unit target, we remain on track to generate over $1 billion in revenue this year.”

“In Q2, we began ramping up Intel Arc graphics for laptops with OEMs including Samsung, Lenovo, Acer, HP, and Asus. COVID-related supply chain issues and our own software readiness challenges caused delays.” availability that we continue to work on. The Intel Arc A5 and A7 desktop cards will begin shipping in Q3.”

Now, Intel will have to try to work on DX11 and older APIs or risk waiting until the industry no longer requires anything less than the current next generation APIs available.
