Hardware problems rarely announce themselves directly. They show up as friction. The kind of friction that’s easy to attribute to software bugs, network speed, or just the inherent complexity of large project models. Over time, that friction becomes normalized. Teams adapt their workflows around limitations they’ve stopped questioning, and the performance baseline shifts without anyone formally deciding that it should.
That friction your team is experiencing isn’t an inevitable outcome of doing complex work — it may be your hardware that’s holding you back.
In this blog, we’ll outline five things that could be holding your team back so you can determine if hardware is the actual problem.
1. Revit Load and Save Times Are Measured in Minutes
Opening a central model or syncing with central should be a brief interruption, not a workflow event. When those operations start taking two, three, or five minutes on a regular basis, the hardware is usually part of the explanation.
Revit’s file I/O performance depends heavily on storage speed. On older SATA SSDs, and especially on spinning hard drives, the sustained read and write speeds are a genuine bottleneck for large model files. NVMe storage at PCIe Gen 4 speeds makes a measurable difference for load and save operations on large files. If your team’s machines are running Revit off anything slower than an NVMe drive, the storage is costing them time every single day.
2. Viewport Navigation Lags on Models That Aren't That Large
When a Revit model that isn’t unusually complex or large results in sluggish 3D navigation, it’s usually a CPU clock speed problem. The viewport rendering pipeline for Revit’s standard engine is single-threaded. A processor with a high core count but a modest boost frequency will produce noticeably worse viewport performance than a processor with fewer cores and a higher clock.
This is one of the most commonly misdiagnosed Revit performance issues. Teams assume the model is too large or too complex, when the actual constraint is that the CPU can’t push single-threaded calculations fast enough to keep the viewport responsive. Upgrading to a processor with a higher single-core boost frequency resolves this problem directly.
3. Enscape or Other Rendering Tools Run, But Don't Really Perform
A machine that can technically launch Enscape and produce a render is not the same as a machine that can use Enscape productively in a client-facing workflow. If your team has Enscape installed but avoids using it for live client sessions because the performance is inconsistent or too slow, the GPU is almost certainly the constraint.
Real-time rendering tools like Enscape, Lumion, and Twinmotion have minimum VRAM requirements for professional use. A GPU with 4 GB of VRAM will run the software, but it won’t run it well on any model of meaningful complexity. If the GPU in your team’s workstations was configured without real-time rendering workloads in mind, it’s probably the reason those tools feel frustrating rather than useful.
4. Coordination Sessions Are Bottlenecked on One Machine
When a Navisworks coordination session is limited by the speed of a single machine, and that machine is the bottleneck for the entire team’s coordination progress, the RAM configuration of that machine is worth examining. Navisworks loads the full-federated model into system RAM. On projects where the combined model size approaches the physical RAM limit of the machine, the application degrades in exactly the way that makes coordination sessions miserable: slow navigation, long clash test processing, and periodic instability.
The machine that’s bottlenecking your coordination sessions may be running Revit fine. RAM demand profiles are different between the two applications, and a machine well-spec’d for authoring can still be under-spec’d for coordination.
5. Your Team Has Developed Workarounds for Their Hardware
This one is harder to see from the outside, but it’s often the most telling sign. Teams that have outgrown their hardware develop informal workarounds: keeping fewer applications open simultaneously, saving local more frequently to avoid long syncs, reducing view complexity before opening 3D views, or scheduling coordination sessions at off-hours to minimize other system load.
None of these are bad practices in isolation. However, when they’ve become standard operating procedure because the hardware requires them, that’s a signal worth examining. The workarounds are productive time that isn’t being spent on the project.
