Duplicated Navigation Wheel & Cursor Lag

[CCCorpCAD3]

Has anyone else experienced severe lag and duplicated navigation wheels in Revit LT 2025 or 2026?

Every time I use the full navigation wheel, the cursor stutters and the wheel duplicates itself endlessly across the screen (screenshot attached). It becomes nearly impossible to navigate a model smoothly.

I initially thought it was my system, so I wiped and reformatted my computer. No change. Now I’m apparently expected to upgrade my RAM, CPU, or GPU just to run a version of Revit LT that looks identical to 2023. The performance hit is real, and it makes no sense given the lack of new features.

Is this a known issue? Any fixes? Or is this just the new norm?

If you care...

My theory? Autodesk keeps inflating the hardware demands of Revit LT—not to push users to full Revit, but to justify their subscription model.
The product barely changes visually or functionally, yet performance keeps getting worse. It’s laggier, needs more power, and still looks like it did two versions ago. Instead of real improvements, they’re just making it heavier, forcing users to upgrade hardware. Go figure what that business strategy is.

Maybe a graphics driver problem. What kind of GPU do you use?

[CCCorpCAD3]

Yeah, that’s exactly what my post is about—being told I might need more RAM, CPU, or GPU. But Revit 2023 runs perfectly on this same machine. No lag, no stuttering. And 2025/2026 look identical to it, so it’s hard to see why the performance would tank unless something under the hood changed.

There’s gotta be a product manager making decisions around this. Does anyone know how to actually get in touch with someone at Autodesk who owns this? Would be great to understand what’s really going on.

Revit has always been a resource-hog, nothing new there. Except for the GPU - it hardly uses the more advanced GPU functionality. In that respect, you can use just about any graphics card or embedded graphics. It's things like Enscape or Twinmotion demanding a powerful GPU.

If you experience severe lag, check out Taskmanager to see what's going on. Could very well be a Windows thing?

Thank you for the follow-up. Did you read my full posts? I'll summarize it here. Same file on Revit LT 2023 runs fine. Same file on Revit LT 2025 or 2026 looks laggy. All of these versions look the same.

See attachments. Look how Revit windows looks vs task manager at the time.

Never seen this in any version of Revit, but then - I don't use LT.  Check out the graphics settings and look what happens if you switch on / off Hardware Acceleration:

I'm guessing hardware acceleration like @Simon_Weel refers to.

Also are all drivers up-to-date?

Also memory, already 72% in use with Revit 800Mb, and Chrome 3GB + Chrome also @8% processing?....how much GB Ram do you have?

I'm mainly still working in Revit 2023, and mostly above 2GB ram for a Revit Session, medium models (3-4 sessions)

Specs of system, Windows 11?

Revit 2025 and higher are using a different windows .NET architecture, maybe something interfers with it (or some misinstalled libraries due to antivirus/firewall)?

Does this also happen in Revit 2024

[CCCorpCAD3]

Thank you Simon. I tried this. It got rid of the wheel problem but made navigating the model laggy 😕

[Simon_Weel]

I guess there's always a trade-off. You still haven't revealed the graphics card in use?

[CCCorpCAD3]

Yes, it the graphics have the latest driver update.

16GB of Ram.

Windows 11.

I don't know about Revit 2024 😕

[CCCorpCAD3]

I have Intel iRISxe

[Simon_Weel]

Right, if I search the Autodesk website, it serves quite a number of hits for Intel Iris xe.

Thanks again Simon! My whole thing is why is Revit 2023 totally fine and Revit 2025 and 2026 not. Where all the versions look identical.
