What matters
- Graphics
- Critical
The GPU sets frame rate and quality in the editor, and handles scaling, overlays and hardware encoding for streaming. Ray tracing and large worlds also need video memory. - Processor
- Critical
Each live input and encode uses CPU time, and fast cores shorten code and shader compiles. Intel Core Ultra adds Quick Sync hardware decoding and encoding. - Memory
- Important
Enough for multiple inputs, replay buffers and large projects. 64 GB is a comfortable start. - Storage
- Critical
Fast NVMe drives for recording several streams at once, and for the project and shader cache. Capture cards use PCIe slots.
