In brief
- The Rendering Quality slider has four levels — Draft, Medium, High and Ultra — each directly affecting GPU load.
- When Auto Resolution is enabled, Enscape automatically lowers the viewport resolution as FPS drops; this only affects the real-time view and does not affect export quality.
- NVIDIA DLSS is not supported on GTX 1660, NVIDIA T1000 and T2000 cards, and leaving RTX features enabled on these cards can cause performance issues.
- Using a Section Box in Revit prevents unnecessary geometry from being sent to Enscape, shortening loading times.
One of the most common problems in architecture and interior design offices using Enscape is FPS drops and blurry images on complex projects or entry-level hardware. Chaos's official Enscape documentation highlights a few key settings to fix these issues. This guide applies to the Enscape plugin working with SketchUp, Revit, Archicad, Rhino and Vectorworks.
How does the Rendering Quality slider work?
The most important setting determining Enscape's real-time performance is the Rendering Quality slider found under the Visual Settings › Main tab. This slider directly determines how much GPU power is spent calculating scene lighting.
| Level | Recommended use | Effect |
|---|---|---|
| Draft | Weak hardware, quick previews | Only direct light is calculated, reflections are simplified, maximum performance |
| Medium | Mid-range GPUs | Path Tracing kicks in, light bounces off one surface to illuminate a second surface |
| High | Presentation-quality render needs | Reflections hide fewer objects, colored glass affects lighting and fog |
| Ultra | Final visuals | Two light bounces are calculated compared to High, the difference is usually barely noticeable |
According to the documentation, at High quality in walkthrough mode, two performance optimizations automatically kick in: skipping the Fresnel term saves about 2-4 percent, and using the average albedo color for diffuse global illumination saves about 3 percent in frame time. These optimizations apply only during walkthrough; no approximations are applied during final captures, and rendering is done at full quality.
Step-by-step performance improvement
Open the
Enscape Toolbar › Visual Settingswindow and lower the Rendering Quality slider on the Main tab by one notch.Check the resolution under
Output › Resolution; high resolutions chosen for export (up to 8192 x 8192 pixels) can strain the GPU and in extreme cases cause Enscape to crash.On Windows, enable
General Settings › Rendering › Auto Resolution. This setting only reduces the real-time walkthrough view and does not affect render output.If the image looks blurry, lower Rendering Quality first; according to the documentation, blurriness caused by dynamic resolution can be resolved this way.
Disable grass and carpet geometry by turning off
General Settings › Rendering › Grass/Carpet Rendering; this provides a slight performance boost.Enable the
Restmodefeature, which stops animations a few seconds after movement ends; animated models can use far more GPU memory than non-animated ones.On RTX-capable cards, turn on
General Settings › Rendering › NVIDIA DLSS, but this requires Auto Exposure to be enabled in Visual Settings.
Memory issues and ray-tracing features
The Ray-traced sun shadows feature uses GPU memory intensively; when memory runs low, this feature automatically disables itself, and the render engine must be restarted to re-enable it. Similarly, the Ray-Traced Artificial Light feature can significantly increase VRAM usage; if problems occur during high-resolution panorama and video exports, disabling this feature is recommended.
The documentation states that DLSS and hardware-accelerated ray tracing are not supported on NVIDIA GTX 1660 series cards or NVIDIA T1000 and T2000 cards; since leaving RTX features enabled on these cards can cause performance issues, it is recommended to disable RTX on this hardware.
Impact on the architectural visualization workflow
These settings are especially important for interior design and architecture offices preparing presentations on entry-level laptops. On complex projects, keeping Rendering Quality at Draft or Medium and switching to High or Ultra for the final presentation ensures smooth modeling while preserving quality before delivery. For Revit users, hiding unnecessary geometry with Section Box is a simple but effective way to shorten loading times on large BIM models. Offices preparing VR presentations should also keep in mind that quality levels behave one notch lower in VR.
Common mistakes
Forgetting to restart the render engine after Ray-traced sun shadows automatically disables, and not understanding why the feature stops working.
Enabling DLSS but forgetting to turn on Auto Exposure in Visual Settings; in this case DLSS won't work as expected.
Leaving RTX features enabled on cards like GTX 1660, T1000 or T2000, resulting in performance problems.
Saving lossless video exports to the desktop; this setting creates hundreds of PNG files, leading to file clutter.

Since most offices in Turkey work with mid-range GPUs, using the Rendering Quality slider correctly provides real time savings. Modeling at Draft or Medium before a presentation and switching to High for the final capture strikes a practical balance between a smooth working experience and quality output.
On the hardware side, it's important for offices using cards like GTX 1660, T1000 and T2000 to keep their RTX and DLSS expectations realistic; the documentation clearly states that additional performance issues can occur on these cards. Also, for large-scale projects using Revit, the Section Box habit is a simple step that can make a noticeable difference in loading times.
Frequently asked questions
How is low FPS fixed in Enscape?
First lower the Rendering Quality slider, then enable Auto Resolution on Windows; unnecessary geometry in the scene can also be cleaned up to reduce GPU load.
Why does the render view look blurry in Enscape?
According to the documentation, when the GPU is strained, resolution automatically drops due to dynamic resolution and the image becomes blurry; in this case, lowering Rendering Quality can fix the issue.
Which cards don't support NVIDIA DLSS?
DLSS and hardware-accelerated ray tracing are not supported on NVIDIA GTX 1660 series cards or NVIDIA T1000 and T2000 cards.
