<\/a>For GeForce RTX owners, Blender offers not only powerful but above all highly performant tools. NVIDIA GPUs provide robust hardware acceleration for the program\u2019s features, which is integrated by default\u2014no complex installation process is required. Rendering in Blender can therefore leverage the power of NVIDIA\u2019s RT cores, which accelerate high\u2011quality ray\u2011traced 3D rendering by orders of magnitude.<\/p>\n
Rendering in Blender was originally a demanding task for multithreaded high\u2011end CPUs. However, the advanced capabilities of GPUs such as the GeForce RTX 50 series and their ray\u2011tracing acceleration allow GPUs to take over this heavy workload and deliver much higher performance to the user. The GeForce RTX 50 series provides crucial viewport acceleration in Blender\u2014used while working on models and scenes for previews\u2014and at the same time directly accelerates final production renders in Blender\u2019s main renderer, Blender Cycles.<\/p>\n
This opens the door to higher\u2011quality output and much greater productivity. You can create instead of waiting.<\/p>\n Blender renders 3D graphics using ray tracing via its Cycles engine. Cycles is flexible and supports execution on devices such as GPUs in addition to CPU execution. As a compute backend for rendering, Blender can use NVIDIA OptiX. OptiX is a full\u2011featured, high\u2011quality ray\u2011tracing engine developed by NVIDIA, and Cycles has long supported offloading heavy ray\u2011tracing compute loads to the GPU via OptiX.<\/p>\n OptiX can directly utilize RT cores in NVIDIA GeForce RTX GPUs, unlocking the same high performance in Blender as seen in the latest games. OptiX also provides powerful AI denoising that leverages Tensor cores in NVIDIA GPUs, and it benefits from Shader Execution Reordering\u2014an area where the Blackwell architecture in the GeForce RTX 50 series has significant improvements. Below you can see the performance gains that GPU acceleration in Blender delivers on GeForce RTX 50\u2011series hardware, as measured on a mobile GeForce RTX 5080 with 16 GB of memory in a Gigabyte Aorus Master 16 BYH laptop. That laptop is equipped with one of the most powerful mobile CPUs, the Intel Core Ultra 9 275HX, and 32 GB of RAM. Measurements used the publicly available Blender OpenData Benchmark version 5.1.0 and NVIDIA Studio drivers 595.79.<\/p>\n As shown, using a powerful NVIDIA GeForce RTX 5080 GPU can significantly shorten render times even compared with high\u2011end multithreaded processors such as the Intel Core Ultra 9 275HX (24 cores) installed in the Aorus Master 16 BYH. In our tests, GPU rendering was up to 11\u00d7 faster than the CPU.<\/p>\n Tests were run on Windows 11 with the power plan set to \u201cBest performance\u201d (when plugged in) and \u201cBalanced\u201d (on battery). The laptop\u2019s GiMATE utility was set to \u201cCreator Mode\u201d.<\/p>\n The benefits of the GeForce RTX 50 series for creative work in Blender go beyond raw speed. NVIDIA GPUs provide special acceleration for motion blur\u2014the effect that blurs moving objects\u2014which can be used directly in Blender. Motion blur adds realism to moving objects, approximating the look of real film capture, and it can also convey motion in a single static frame. It\u2019s therefore an important tool for compositing 3D scenes.<\/p>\n GPU\u2011accelerated motion blur on NVIDIA hardware enables rendering this effect at full quality and with realistic simulation as part of the scene render. This is a higher\u2011quality alternative to faking motion blur with a post\u2011processing vector effect applied within the scene’s setup, which creators sometimes use because full motion\u2011blur simulation during rendering is computationally expensive and lengthens render times.<\/p>\n Such substitute approaches lack realism and can introduce visual artifacts and errors, as highlighted in the image above. Although the effect is inferior, it\u2019s sometimes used because full simulation of motion blur during frame rendering consumes a lot of compute and increases render time.<\/p>\n GPU acceleration enabled by GeForce RTX 50\u2011series cards solves this problem\u2014thanks to high performance it allows full\u2011quality motion blur to be rendered as part of the rendering process. That delivers full image quality without forcing you to wait and sacrifice productivity.<\/p>\n Another extremely compute\u2011intensive challenge in rendering 3D scenes is volumetric effects\u2014simulating flowing liquids, moving smoke clouds, flames and similar phenomena. Achieving convincing, visually realistic results requires computing millions of physical simulations. Beyond compute intensity, volumetric rendering is also extremely memory\u2011hungry because volumetrics require decomposing an object into many voxels that must all be analyzed to simulate light interaction within these complex volumes.<\/p>\n GeForce RTX 50\u2011series GPUs enable the use of NanoVDB for volumetric rendering, which optimizes these techniques for GPU execution. Crucially, NanoVDB allows volumetric computations to be performed with orders\u2011of\u2011magnitude lower graphics memory usage\u2014a scarce resource. With NanoVDB, much larger scenes can be processed on the GPU, whereas without it you\u2019d be forced to sacrifice scene detail and realism. The benefits of NanoVDB grow with the complexity and intricacy of the volumetric objects and effects in a scene.<\/p>\n A final special advantage of GeForce RTX 50\u2011series GPUs we\u2019ll discuss here is support for a new primitive for modeling\u2014linear swept spheres (LSS). The GeForce RTX 50 series added LSS as a new graphics primitive that GPUs can process, and with OptiX support you can now use them in Blender.<\/p>\n LSS are conical or cylindrical shapes capped on one or both ends by spherical surfaces. They can connect at their tips, making them well suited for realistic hair or animal fur simulation. LSS simulate not just approximate volume but individual hairs.<\/p>\n Simulating hair with LSS is far more realistic and flexible than previous approaches, and it\u2019s also an efficient simulation method. LSS typically require only one vertex per hair bend, so they consume far less geometric engine performance on the GPU than alternative, more complex hair simulation methods.<\/p>\n This method requires 2\u00d7<\/b> less compute than rendering hair with DOTS primitives (Disjoint Orthogonal Triangle Strips). Thanks to the simplified 3D model, it also significantly reduces memory usage\u2014the consumed capacity is 5\u00d7<\/b> lower.<\/p>\n These factors allow rendering much more complex and higher\u2011quality representations of hair and fur than before, provided you have GeForce RTX 50\u2011series hardware that supports LSS primitives.<\/p>\n High performance isn\u2019t needed only for final renders. For high productivity during creation, it\u2019s even more important to have high\u2011quality previews available in the viewport at all times. That\u2019s not trivial when working on complex objects and scenes.<\/p>\n Fortunately, you can rely on the GeForce RTX 50\u2011series for viewport rendering as well. Blender can accelerate this function via OptiX, so previews also benefit from fast rendering using the GPU\u2019s RT cores.<\/p>\n Here you can see an example of how viewport acceleration increases the performance of the same Gigabyte Aorus Master 16 BYH laptop with an Intel Core Ultra 9 275HX and 32 GB of RAM that we used in the first test\u2014if you select its NVIDIA GeForce RTX 5080 GPU with 16 GB of memory for processing.<\/p>\n<\/a>Rendering powered by RT cores<\/h3>\n
\nBy using the GPU\u2019s hardware capabilities through OptiX, GeForce RTX cards achieve leading rendering performance in Blender\u2014while also offering better energy efficiency than CPU rendering, which is especially important on laptops.<\/p>\n<\/a><\/p>\n<\/a>High\u2011quality motion blur without performance penalties<\/h3>\n
