**D5 Render Version:**3.0
**Graphics Card:**RTX 5080
**Driver Version:**32.0.15.9186
Issue Description:

I just upgraded my GPU TO A 5080, added 32G DDR4 memory (64 total), new 850W PSU, and a new AIO cooler. I currently have a i5-10600k CPU.
Would upgrading to a i9-11900k (the newest my mother board will handle) significantly change my speed and stability when working with large sites with several buildings in D5 ?

I’m migrating to D5 3.0 from Lumion 12.5 and want to max out my computer within a small budget. Because Lumion 12.5 didn’t have ray or path tracing it handled large sites easily
but D5 struggled with same large model hence the computer upgrades. I’m very excited to switch to D5 and want it to easily handle these types of projects.
Thank you

Hi @clois

There’s only a small difference when upgrading your CPU for D5 Render.

Although it has some effects like scene loading, geometry processing, and simulation calculations.

However, compared to other rendering softwares like Lumion, D5 is primarily GPU-accelerated for real-time rendering, so a powerful GPU usually has a greater impact on rendering speed and smoothness.

Note: A balanced system with a modern CPU and a high-performance GPU will deliver the best experience.

Thank you for your reply.
The GPU dosen’t rely on the CPU while creating a scene (like for scatter calculations) at all ?
