Performance Considerations

Why do I have a low frame rate?

There are several reasons why your frame rate (fps) might be low, resulting in single frames being strongly noticeable when moving in Enscape.

Your computer’s system specifications are too low

  • Enscape renders using only a dedicated GPU. A GPU such as an NVIDIA GTX 1660 or higher is recommended and the more VRAM there is on the GPU, the better Enscape will generally perform (although when using VR, the clock speed of the GPU processor is the more limiting factor on the higher end GPU’s required for VR). It’s worth checking our System Requirements from time to time and on each release as these are subject to change.

Your project is too large

  • Project size can be, but is not always, an issue. Projects containing a lot of fine tessellated geometry, such as pipes, cables, and furniture, or lots of high-res textures might overwhelm your computer. Hiding small but detailed elements in your project can help.

Performance issues can generally be improved by adjusting the Rendering Quality, under the Visual Settings window – Main tab, to a lower value. We recommend setting this to High if you find performance sub-optimal. This will boost performance by turning off some of the more expensive rendering features.

Setting the Rendering Quality to Draft will give you the best performance, but at the expense of losing reflections.

This will boost performance by turning off some of the more expensive rendering features.

Your screen resolution is too high

  • You can increase your real-time performance by simply adjusting the size of the Enscape window. However, when you are wanting to render an image out, make sure that the Resolution is set to the desired resolution for the final render, and not set to Window. Here you can see that the Capture Resolution is set to FullHD, which is the equivalent of ‘1080p’.

Further Performance Settings

Enscape provides further options to enhance performance such as and these can be found under the General SettingsRendering tab:

NVIDIA RTX Ray Tracing – In cases where RTX is causing memory issues. RTX is enabled by default and a restart of Enscape will be required when toggling this feature.

NVIDIA DLSS – Deep Learning Super Sampling is an RTX technology that uses AI to boost frame rates, meaning high resolutions can be used whilst maintaining a solid frame rate (Auto Exposure needs be enabled in the Visual Settings when DLSS is activated).

NVIDIA Denoiser – Uses AI to guess what the image should look like without the noise.

Ray Traced Sun Shadows (for all images) – Enabling this will enable ray-tracing for shadows instead of using shadow maps and will provide a higher level of shadow detail.

Grass/Carpet Rendering – When disabled, a slight performance increase can be had, but carpet and grass will geometry will not be rendered.

Restmode – When enabled, animations will stop a few seconds after you cease movement in the Enscape viewport.

NOTE regarding DLSS
If DLSS appears not to be functioning for you, please make sure you are running the very latest GPU drivers, as recommended here, and also make sure that Auto Exposure in the Visual Settings is enabled.

If you have a machine that has an NVIDIA RTX 30XX GPU as the dedicted GPU, but also has an iGPU (CPU) from the AMD Ryzen 7 5800H and AMD Ryzen 9 5900 range and DLSS is causing issues, then you will also need to additionally install the AMD Q21.6.2 driver to resolve the issue.
With the NVIDIA GTX 1660 product line DLSS is not supported even though the GTX 1660 cards can run RTX features, many performance issues are likely. In this scenario we highly recommend disabling RTX for these GPU’s.

How can I decrease the loading time?

For some projects, Enscape’s initial loading time can take a few minutes whilst it loads all the information required.

Loading time is also determined by how quickly the CAD software can communicate the content of the project. The more complex your project is in the CAD software, the longer it may take for Enscape to load. To shorten loading times, try the following:


  1. In Revit use the Section Box function which will reduce he amount of information being communicated.

  2. Hide small yet detailed objects, such as cables, triggers, pipes, etc.

  3. Use a dedicated SSD for your CAD installation and project files.

  4. Upgrade your computer. Exporting time is limited by your CPU, RAM and hard disk speed.

  5. Download the newest version of Enscape as we’re continuously working on improving the loading time.
