Model Freezes with Better Computer

Sorry for the confusing title. In my office computer, I am having a problem with SketchUp 2026. I have a model imported from Revit and edited in SketchUp. This model works perfectly, I mean the interface is smooth and no freezing or slowness problems at all.

But even though my computer has a way better system, this specific model freezes for a couple of seconds every 2-3 seconds, which makes working impossible. I tried to check some combination on another computer. Unfortunately, we don’t have another computer with the same specs.

Here I am attaching a comparison video. There are other computers with different specs which did not have the same problem. One of them even 8 years old system.


What I tried so far:

-NVIDIA Control Panel → Manage 3D Settings → Program Settings → Add SketchUp 26
-NVIDIA Game Ready driver is switched to NVIDIA Studio Drivers

-Tried to change the graphic setting in SketchUp to classic.

What might be the reason for having this sluggish interface in my computer but not in the other older computers?

Thank you for your time.
Hakan.

Suggestions from Gemini AI

1. Power State Fluctuations (NVIDIA Power Management)

The RTX 4090 is an aggressive, high-wattage card. When handling a model that isn’t pushing its limits, the GPU drops down to a low-power idle state ($P\text{-State}$). When you orbit, it rapidly spukes to a high performance state, then instantly drops back down every 2 to 3 seconds when the input pauses. This rapid cycling causes a momentary clock-speed freeze (voltage regulation stutter).

  • The Difference: The mobile/workstation RTX 2000 Ada has a much tighter power envelope and doesn’t aggressively cycle power states under light workloads.
  • Fix: Open the NVIDIA Control Panel, go to Manage 3D Settings > Program Settings, and select SketchUp. Change Power Management Mode from Optimal Power to Prefer Consistent Performance (or Prefer Maximum Performance).

2. G-Sync / Variable Refresh Rate (VRR) Conflict

SketchUp’s workspace window drops to low framerates when the camera stops moving. If the RTX 4090 system is connected to a high-refresh-rate gaming monitor with G-Sync enabled, the monitor’s refresh rate will rapidly swing between 144Hz+ (during orbit) and 1Hz to 10Hz (static display). This continuous, rapid syncing loop causes cyclical display stuttering.

  • The Difference: Workstation setups running RTX 2000 Ada cards typically use standard enterprise displays without G-Sync/VRR active.
  • Fix: Open the NVIDIA Control Panel, go to Set up G-SYNC, and either disable it entirely to test, or change it from Full screen and windowed mode to Full screen mode only so it stays disabled within the SketchUp window.

3. Precision Mice / Peripherals Polling Rate Conflict

High-end desktop systems paired with an RTX 4090 often utilize gaming mice set to an ultra-high polling rate ($1000\text{ Hz}$ to $8000\text{ Hz}$). When orbiting or moving the camera, this massive stream of coordinate data overloads the single-threaded window processing queue of older win32-based UI frameworks like SketchUp, causing a periodic input freeze.

  • The Difference: Enterprise workstations typically use standard office mice locked at a steady $125\text{ Hz}$ or $250\text{ Hz}$ polling rate.
  • Fix: Open the mouse peripheral software (Logitech G Hub, Razer Synapse, etc.) on the new computer and drop the Report Rate (Polling Rate) down to 250 Hz or 125 Hz.

BTW, your forum profile is way out of date.

Thank you for letting me know. I updated it. And thanks for the suggestion from Gemini. I tried them, and it didn’t change the result.

What Antialiasing setting are you using? Is it the same for both computers? Are the monitors the same resolution? Are you running different extensions in the two?

According to Passmark, the Core Ultra 7 CPU is in fact somewhat faster than the i7-14700KF (it is the single thread performance that counts). CPU performance is more important for SketchUp than GPU performance.

I wonder if something else running is interfering. The row of taskbar icons is much longer on the screen to the right.

Another detail that might give some ideas is that once it freezes, it is not just in the model screen. I mean, the tabs in that SketchUp file or the save window are also freezing.

I also tested this with older computer that has, GeForce GTRX 1660ti and Intel i7 11700. Monitors are different though, and for plugins probably they are not excatly the same. But I will try to uninstall all extentions and try to test it with the defaul Sketchup Version.

Btw this is the only imported model from revit, so I couldnt check it properly but I have also very heavy models I tested in my computer. They work smooth and fast but those ones doesnt have any revit imported parts. Done fully in sketchup.

Sorry for the flood of messages but I tried downgrade the sketchup to 2025 with default version (with out any plugin) it started to work smooth. Then I removed all the files related with 2026 and re-install it to have fresh default setup. The model is working perfectly now. It must be related with one of the plugins I have only in this computer. I used migrate feature and let it take all information from 2024 version I have been using during my first 2026 installation. I will tryto add my plugins one by one to understand which one is causing this problem.

Somehow I solved the problem and once I findout which plugin causing this problem, I will update here.

Thanks for all your suggestions.

If the problem persists:

Are you running the classic or new graphics engine? Is it the same on both machines? Does switching change anything? IIRC wasn’t the new engine on by default in 26?

Are both monitors using the same type of connection? HDMI / DisplayPort / etc?

To me that suggests there is something external to the model itself causing that.
Do a fresh SketchUp install with no extensions and test that.

If it’s still happening then I’d be looking away from
SketchUp itself and perhaps to sometime the machine is doing in the background or a setup issue.

It looks like you have SketchUp on the main screen on one and the 2nd screen on another. How is each machine connected to the 2 displays?

Interesting video.

The fact that the same model runs fine on other computers makes this a really interesting case.

Since the model was imported from another software, I’d be curious to see if there are any unusually heavy components, textures, or imported geometry contributing to the issue.

I built a small SketchUp model diagnostics tool called nEVEn for investigating this kind of thing.

If you’re comfortable sharing the model, I’d be happy to run a scan and share what I find.

No charge. Just genuinely curious what’s causing the difference between the systems.

I also posted a short viewport lag example on YouTube recently if you’re curious how the diagnostics work.

Could it be an issue with the SketchUp program autosaving? Look under Windows>Preferences>General>Autosave. With large files, it could cause a lag.

Thanks to everyone for sharing your guesses. It was so frustrating at that time to have way worse performance on a way better computer.

Just after I shared this problem, I had an overheating problem on my i7-14700KF. Apparently, it is one of the processors affected by Intel’s documented Vmin Shift Instability issue. Long story short, we sent the processor to Intel, and it was replaced with the new one. That problem is solved. I thought the previous problem was about this processor problem.

Even after I installed the new processor, the problem was still there. By doing a fresh install and installing my plugins one by one, I was finally able to diagnose the problem.

I have been using Eneroth Reference Manager for the last two years for large-scale projects. I was keeping it disabled if I was not using it. But apparently, still, that was the one causing that repeating freezings. When I installed it after the fresh SketchUp 2026 installation, I had the same problem. Then I uninstalled it, and after a restart, it was performing smoothly.

I wanted to share this experience in case it happens in a same/similar scenario to someone else. So yeah, no more “Eneroth Reference Manager” if I am working on a Revit imported model. Because I also worked with even heavier models before with this plugin perfectly, but those were the models done in SketchUp only, without any imported parts.

Thank you for spending your time on this.

Maybe @eneroth3 is interested in your findings..
