The Best 3D GPU-accelerated Software 2021

A GPU render engine, or GPU-accelerated renderer, is an engineered program based on such disciplines as light physics, mathematics, and visual perception. There is a wide variety of GPU renderers on the market today, some of which offer both CPU-based rendering solutions and GPU-based rendering solutions, and the capability to simply switch between the two with a single click. Popular examples of GPU renderers include: Arion (Random Control), Iray (NVIDIA), Octane (Otoy), Redshift (Redshift Rendering Technologies), etc

Some advantages of GPU rendering include:

  • Scalability in multi-GPU rendering setups.
  • GPU rendering solutions consume less power than CPUs.
  • Speed boosts – many modern render systems are suited for GPU software and hardware, which are designed for massively parallel tasks and can provide overall better performance.
  • Lower hardware costs due to the increase in computation power.

D5 Render is a real-time renderer based on real-time ray tracing technology. In fact, it combines the benefits of both ray tracing and rasterization to get real-time interactivity and photo-realistic images simultaneously. Although it just came to the market in more than 1 year, it has a lot of potential to show. D5 Render is free for the Beta version (version 1.6 or lower). It is planned to release a community version for free, which is lightweight and serves well for individual usage and educational purposes. Commercial version is much cheaper than Lumion, with 480 USD per user, with perpetual license and lifetime free upgrades. 

  • Pros: For D5 Render, SketchUp 3Ds Max and Revit, Rhino, Blender and ArchiCAD are supported now. What is good about D5 Render is that developers released the D5 converter plugin for 3Ds max, which will help your model to remain almost all material and material properties. 
  • Cons: However, you will need to convert your model to V-ray to keep all material, then export to D5 Render. It does not support converting from Corona or Fstorm. So if your file is in Corona or Fstorm, you will need to convert to V-ray, then export to D5 Render.

If you’ve been using Blender, you might be familiar with the name “Cycles”. That’s the name for the ray-tracing renderer inside Blender, but upon release of version 2.8, a new real-time renderer was implemented called “Eevee”. Eevee is focused on real-time rendering, using clever speedy tricks to sacrifice as little realism as possible when compared to Blender’s realistic Cycles renderer.


  • Render time is greatly reduced.
  • Settings can be more intuitive to play with for beginners.
  • It can give faster and similar results in some scenes compared to Cycles.


  • It doesn’t provide the realism that Cycles does.
  • Some scenes must be made and tweaked in Cycles before they can render properly.
  • Some materials don’t work immediately.

With Unreal Engine, you can bring amazing realtime experiences to life using the world’s most advanced realtime 3D creation tool. From first projects to the most demanding challenges, our free and accessible resources and inspirational community empower everyone to realize their ambitions. Since 2015, Unreal engine can be downloaded for free, with its source code available on a GitHub private repository. Epic allows for its use in commercial products based on a royalty model,  typically asking developers for 5% of revenues from sales.


  • Licensing model: Since you are not paying anything at the front you have a full-powered, unrestricted engine at your fingertips and you only pay royalties once your earning reaches a certain threshold. For starters, the deal is not bad at all.
  • Performance: The engine’s performance is at the top of the industry.
  • Good support for Steam and other similar ecosystems
  • Open Source: If you have the knowledge of C++, you can modify it to fit your needs.


  • Can be Overwhelming for one person: Unreal is better suited for teams than a single person, which makes the learning curve so much steeper.
  • It’s free until you start making over $25.000 per quarter.

Enscape is a real-time 3D rendering software that is primarily geared at architectural visualization. Impressively, this solution eliminates the need to export from BIM software and rework data for presentations as still images or movies. Everything is prepared in the original program.

However, the standout feature of this 3D rendering software is its ability to export project files from Revit, SketchUp, Rhino, and ArchiCAD as standalone executables to provide walkthroughs that can be shared with clients or co-workers. These executables can be used on desktop computers and VR goggles.

  • Pros: Fast and easy to use (depending on the hardware you have), Broad assets library, Price

It is easy as pie to start these walkthroughs. But Enscape is also a great tool to support the designing process. The link between the presentations and the original CAD data means that you can inspect and evaluate any changes you make in a snap. Apart from the photorealistic render mode, Enscape includes several stylized modes like sketch, paper and polystyrene models.

  • Cons:
  1. Medium quality final renders
  2. Materials can’t be edited
  3. Hard to create representative model videos

Touted as the world’s first fully 3D GPU-accelerated software biased renderer by its developer, Redshift offers the flexibility and quality of CPU-based rendering with GPU-based speed.

Unbiased engines tend to be very difficult for artists to render with as they are much more precise with their calculations regarding processes like lighting physics. However, Redshift is a biased engine, meaning there is much more freedom for the artist to get the desired render without having to overwork settings — meaning you can focus solely on creating.

Redshift is easily integrated into programs such as Cinema 4D, Maya, and Houdini, making for very powerful workflows and beautiful results.

  • Price: $500 / license
  • Software: 3ds Max, Cinema 4D, Houdini, Maya, Softimage
  • Redshift supports a maximum of 8 GPUs per session.
  • Pros: Fast GPU-accelerated rendering, Out of Core (OOC) capability

In order to get this powerful renderer, users need to invest from $295 per year. Developed by NVidia, Iray is a biased GPU renderer that’s one of the best 3D CAD rendering software aimed at beginners, students and hobbyists who don’t have expert rendering knowledge, as well as professionals. 

However, while it may be beginner-friendly, Iray’s quality shouldn’t be underestimated. This intuitive, physically based rendering technology uses AI denoising, CUDA, NVidia OptiX and Material Definition Language (MDL) to generate photorealistic imagery with great speed and efficiency, making it one of the most realistic 3D rendering software. To explain that in more detail, AI denoising is the use of Tenor Cores on the latest NVidia hardware to bring the power of deep learning to both final-frame and interactive photorealistic renderings. This speeds up the completion of final images and smoothes interactive rendering, producing a faster understanding of your scene’s composition and lighting.
