Emulating PC games on your non-Snapdragon device just got better
Hadlee Simons / Android Authority TL;DR GameSir has announced that its GameHub app now offers much better support for MediaTek chipsets with Mali GPUs. The company also revealed that it's working with MediaTek to launch custom Mali GPU drivers. GameHub lets people play PC games on their Android phones without streaming. There are a few ways to natively play PC games on your phone without streaming, with Winlator and GameSir's GameHub app being the most popular solutions. These apps traditionally offer better support for Qualcomm Snapdragon devices, but there's good news if you've got a MediaTek-powered device. GameSir announced via its app that the latest version of GameHub offers much better support for devices with Mali GPUs. It points to devices with MediaTek Dimensity chips, specifically mentioning the Dimensity 9000 to 9400 processors. It says these devices should support DirectX9 to DirectX11 PC games 'with performance comparable to Qualcomm Adreno, and even surpassing it in some scenarios.' The GameHub team delved into some technical challenges with Mali GPUs, starting with the unsatisfactory Vulkan implementation. It pointed to issues like 'unstable' shader compilers and missing driver capabilities. So how did GameSir address these problems? For one, the team said it invested time and resources in debugging/analyzing Dimensity devices and 'optimized' resource scheduling. Furthermore, it created a 'code conversion mechanism to optimize DirectX instructions into a format executable by Mali GPUs.' The team says it also made runtime optimizations in cases where the driver functionality wasn't adequate. Weirdly enough, the GameHub team also claimed that it offers 'native support' for 32-bit PC games. That sounds rather crazy, as compatibility layers like Wine or tools like Box can incur a performance penalty and technically don't offer native support. In some major news for mobile gamers, GameSir also said it's teaming up with MediaTek to eventually offer custom GPU drivers. We plan to jointly launch custom drivers with MediaTek, specifically designed for GameFusion, to address long-standing Mali GPU issues at the chip level, further enhancing the gaming performance of Dimensity devices. There's no release timeline for these drivers, though. This is still welcome news, as one major advantage of Snapdragon devices is the prevalence of open-source Adreno drivers (dubbed Turnip). These drivers can improve emulation/gaming performance and address bugs. MediaTek isn't the only chipmaker using Mali GPUs, though. Google Pixel phones with Tensor chips use Mali GPUs too. We've asked GameSir's representatives whether some of these improvements will filter down to Pixel phones. We've also asked the representatives for more details on 'native support' for 32-bit PC games. We'll update the article when the company gets back to us. Nevertheless, we hope a few of these improvements and optimizations come to Pixel devices. However, Pixel 10 rumors suggest that Google will switch to Imagination GPUs. So even if these upgrades apply to Pixel phones with Mali graphics, it won't apply to the Pixel 10 series. Got a tip? Talk to us! Email our staff at Email our staff at news@ .

Nvidia teams up with Microsoft to put neural shading into DirectX, giving devs access to AI tensor cores
When you buy through links on our articles, Future and its syndication partners may earn a commission. Nvidia and Microsoft announced on Thursday that they would be adding neural shading support to the Microsoft DirectX preview this April. Neural shading will use cooperative vectors and Nvidia's Tensor cores (matrix operations units) to speed up graphics rendering in games that support the technology. It will better allow for the generic use, via HLSL (high level shading language) of traditional rendering techniques alongside AI enhancements. While real-time computer graphics and graphics processing units (GPUs) have come a long way, the graphics rendering pipeline itself has evolved slower than hardware. In particular, while Nvidia's GPUs have featured Tensor cores (primarily aimed at AI compute) for over seven years now, they have only been used so far for things like upscaling (Nvidia's DLSS), ray reconstruction (DLSS 3.5) and denoising, and frame generation (at least for DLSS 4). This is going to change with the so-called neural rendering — a broad term that describes a real-time graphics rendering pipeline enhanced with new methods and capabilities enabled by AI. A specific subset of neural rendering focused on enhancing the shading process in graphics is called neural shading. Its main purpose is to improve the appearance of materials, lighting, shadows, and textures by integrating AI into the shading stage of the graphics pipeline. The addition of cooperative vectors — which allow small neural networks to run in different shader stages, like within a pixel shader, without monopolizing the GPU — is a key enabler for neural shading. Cooperative vectors rely on matrix-vector multiplication, so they need specialized hardware, such as Nvidia's Tensor cores, to operate. To that end, they can potentially work on Intel's XMX hardware as long as they meet Microsoft's requirements. They may also work on AMD's RDNA 4 AI accelerators, though RDNA 3 seems more doubtful (as it lacks AI compute throughput compared to the competition). Still, Microsoft is working with AMD, Intel, Nvidia, and Qualcomm to ensure cross-vendor support for cooperative vectors over time. "Microsoft is adding cooperative vector support to DirectX and HLSL, starting with a preview this April," said Shawn Hargreaves, Direct3D development manager at Microsoft. "This will advance the future of graphics programming by enabling neural rendering across the gaming industry. Unlocking Tensor Cores on Nvidia RTX GPUs will allow developers to fully leverage RTX Neural Shaders for richer, more immersive experiences on Windows." Our understanding — we've reached out to AMD, Intel, and Nvidia for additional comment but haven't heard back — is that the upcoming DirectX preview with cooperative vectors will start as an Nvidia exclusive. Once driver support is available from AMD and Intel, it should work on their GPUs as well. But we'll need to wait to find out not only whether it works, but how well it works — both in terms of image fidelity as well as performance.
