February saw community mods bring resizable BAR support to several older platforms; and now we come across a mod that brings it to some older GPUs. The NVStrapsReBAR mod by terminatorul, which is forked out of the ReBarUEFI mod by xCurio, brings resizable BAR support to NVIDIA GeForce RTX 20-series and GTX 16-series GPUs based on the "Turing" graphics architecture. This mod is intended for power users, and can potentially brick your motherboard. NVIDIA officially implemented resizable BAR support since its RTX 30-series "Ampere" GPUs in response to AMD's Radeon RX 6000 RDNA 2 GPUs implementing the tech under the marketing name Smart Access Memory. While AMD would go on to retroactively enable the tech for even the older RX 5000 series RDNA GPUs, NVIDIA didn't do so for "Turing."

NVStrapsReBAR is a motherboard UEFI firmware mod. It modifies the way your system firmware negotiates BAR size with the GPU on boot. There are only two ways to go about modding a platform to enable resizable BAR on an unsupported platform—by modding the motherboard firmware, or the video BIOS. Signature checks by security processors in NVIDIA GPUs make the video BIOS modding route impossible for most users; thankfully motherboard firmware modding isn't as difficult. There is an extensive documentation by the author to go about using this mod. The author has tested the mod to work with "Turing" GPUs, however, it doesn't work with older NVIDIA GPUs, including "Pascal." Resizable BAR enables the CPU (software) to see video memory as a single contiguously addressable block, rather than through 256 MB apertures.

Microsoft has implemented two new features into its DirectX 12 API - GPU Upload Heaps and Non-Normalized sampling have been added via the latest Agility SDK 1.710.0 preview, and the former looks to be the more intriguing of the pair. The SDK preview is only accessible to developers at the present time, since its official introduction on Friday 31 March. Support has also been initiated via the latest graphics drivers issued by NVIDIA, Intel, and AMD. The Microsoft team has this to say about the preview version of GPU upload heaps feature in DirectX 12: "Historically a GPU's VRAM was inaccessible to the CPU, forcing programs to have to copy large amounts of data to the GPU via the PCI bus. Most modern GPUs have introduced VRAM resizable base address register (BAR) enabling Windows to manage the GPU VRAM in WDDM 2.0 or later."

They continue to describe how the update allows the CPU to gain access to the pool of VRAM on the connected graphics card: "With the VRAM being managed by Windows, D3D now exposes the heap memory access directly to the CPU! This allows both the CPU and GPU to directly access the memory simultaneously, removing the need to copy data from the CPU to the GPU increasing performance in certain scenarios." This GPU optimization could offer many benefits in the context of computer games, since memory requirements continue to grow in line with an increase in visual sophistication and complexity.

Support for AMD's Smart Access Memory and the overarching Resizable BAR technologies has been removed from the RadeonSI Gallium3D OpenGL driver as of today's Mesa 22.3.7 release. The comment in the announcement simply reads, "Disable Smart Access Memory because CPU access has large overhead." The nail in the coffin seems to have been this bug ticket submitted last month for the game Hyperdimension Neptunia Re;Birth1, in which the user reported the game running oddly slow on their RX 6600 while previously they had no issues on the much older R9 380. The solution provided was to simply disable ReBAR/SAM either with radeonsi_disable_sam=true or via UEFI. In the comments of the ticket lead RadeonSI developer Marek Olšák states, "We've never tested SAM with radeonsi, and it's not necessary there."

Apparently the performance advantages weren't panning out for RadeonSI, and since direct optimizations of these features was not a primary goal the decision was made to cut them out. Attempts to optimize SAM with RadeonSI date as far back as December 2020 and Mesa 21.0, but support for SAM under Linux goes further back. None of the changes to RadeonSI will affect other drivers such as RADV, the open-source Radeon Vulkan driver, and this code change is limited to only the RadeonSI OpenGL driver.

Intel has recently published a document outlining the requirements for Arc GPU support on desktop including the supported platforms. The guide states that supported processors are limited to 12th Gen Core "Alder Lake", 11th Gen Core "Rocket Lake", and 10th Gen Core "Comet Lake" with Resizable BAR support enabled on the motherboard. The document also notes that other platforms supporting Resizable BAR / Smart Access Memory may work with Intel Arc graphics cards indicating potential unofficial support for AMD platforms also. Intel has also specified that only Windows 10/11 is supported and installations must be using the GPT partition type. The page contains instructions to enable Resizable BAR support and switch to a GPT partition but no information is provided as to whether the cards will work without this functionality.

TechPowerUp today released the latest version of TechPowerUp GPU-Z, the popular graphics subsystem information and monitoring utility. With the latest version 2.38.0, we are introducing the ability to detect Resizable BAR support. GPU-Z can now tell whether Resizable BAR is supported, and if so, whether it is enabled. AMD refers to Resizable BAR as AMD Smart Access Memory, but it is a feature developed by the PCI-SIG, which lets your CPU see the entire video memory of your discrete graphics card as a single addressable block, rather than through 256 MB apertures. This feature has been found to improve performance in games that can take advantage of it. Resizable BAR status can now be viewed from the main tab, right next to the multi-GPU status.

The latest TechPowerUp GPU-Z also adds support for new and upcoming GPUs, including AMD Radeon RX 6700 XT, RX 6700, RX 6600 XT, RX 6600, and Ryzen "Lucienne" mobile processor iGPUs. Support is also added for NVIDIA GeForce RTX 3070 Mobile. Other new features include the ability to monitor negative temperatures on NVIDIA GPUs.

AMD in its "Where Gaming Begins Episode 3" online event, announced that it is introducing Smart Access Memory (resizable base address register) support to Ryzen 3000 series "Matisse" processors, based on the "Zen 2" microarchitecture. These exclude the Ryzen 3 3200G and Ryzen 5 3400G. The PCI-SIG innovated feature was, until now, restricted to the Ryzen 5000 series on the AMD platform, although is heavily proliferated across the Intel platform. Resizable BAR enables the CPU to see the graphics card's entire dedicated memory as one addressable block, rather than through 256-megabyte apertures. For game engines that are able to take advantage of the feature, this could translate to a performance boost of up to 16 percent. Be on the lookout for BIOS updates from your motherboard manufacturer.

NVIDIA on Tuesday announced a roll-out of its implementation of the PCI-SIG resizable base-address register (BAR) feature to select GeForce products. The feature enables your CPU to see the entire video memory of your graphics card as one addressable block, rather than through 256 MB apertures. This should improve certain kinds of 3D rendering workloads, and game engines that are optimized to use it should see a tangible performance boost. AMD earlier introduced the exact same feature under its marketing name "Smart Access Memory," with its Radeon RX 6000 series.

NVIDIA announced that resizable-BAR support will be made available to GeForce RTX 30-series "Ampere" desktop graphics cards, notebooks that have RTX 30-series "Ampere" mobile GPUs, and future products. The support requires not just a compatible graphics card, but also a motherboard that supports the feature. Most leading motherboard- and OEM desktop manufacturers began rolling out resizable-BAR support through UEFI firmware updates. Using the feature requires you to run your machine in native UEFI mode (with CSM disabled).
