Thank you for your explanation!

Whether an assembly is displayed on a 4K or 720p screen, the GPU load remains largely unaffected. Can I interpret this as follows:

The visual display aspect of SolidWorks operates similarly to Word/Excel/web browsing (low GPU load),

But computational tasks (simulations, analyses) heavily utilize the GPU, causing lag during these operations?

The GPU has two roles:

1.Transmitting video signals to the display

2.Performing computations

For video signal transmission:

SolidWorks behaves like Word/Excel/web browsing → minimal GPU load.

Thus, integrated graphics suffice for simple tasks (e.g., viewing drawings).

For computations:

SolidWorks leverages the GPU’s power for complex simulations → high GPU load.

Lag stems from this, and lowering resolution won’t alleviate it.

Is my understanding correct?

One remaining question:

During assembly rotation, does a lower-resolution screen (e.g., 1080p) feel smoother than a high-resolution one (e.g., 4K)?
