Row	Shows
Advanced Settings	Shows the settings most captures leave as they are in the sidebar’s panels; the same switch as in the Setup panel. See Advanced Settings.
GPU	The GPU SplatPilot trains on, the graphics API and, on NVIDIA cards, its memory, such as “NVIDIA GeForce RTX 4070 · Vulkan · 12 GB”; “Not tested” before the first test. Test GPU beside it; “Testing…” in its place while the test runs.
Speed	After a test: how long one Draft-sized training step takes, such as “3.9 ms per training step at Draft”.
VRAM Limit (GB)	The GPU memory above which the estimate warns; see VRAM Limit.

Test GPU

Test GPU runs a short training on the GPU that SplatPilot uses and fills in the GPU and Speed rows.

The test does three things:

• It tells you which GPU trains and how fast it is.
• It prepares the engine’s shaders, which the very first training would otherwise do (a minute or two at “Preparing the engine…”).
• It gives the estimate in the Create Splat panel your GPU’s speed, so its training times fit your machine from the start. Every finished training refines them further. On NVIDIA cards, the estimate’s VRAM row then shows the training’s VRAM out of the card’s, such as “0.6 of 12 GB”.

The test is not available while something renders or trains, because it would time both: the tooltip says “A render or training is running: it would time both”.

VRAM Limit

VRAM Limit (GB) makes the estimate warn when a training would need more GPU memory than this. The warning comes with a button that lowers Max Splats to the largest budget that fits. 0, the default, never warns.

On NVIDIA cards, Test GPU fills in the limit for you if it is 0: the card’s memory less 1.5 GB, to leave room for Blender’s own drawing. You can change it at any time.

When memory runs short

Other programs and your desktop use GPU memory too. If a training fails with “not enough memory”, close other programs, or lower Max Splats, the view Count or the image size. A lower VRAM limit makes the estimate warn earlier.

Without the training engine

If the engine is missing, the preferences show two lines instead of the rows: “Engine missing (slangpy): reinstall SplatPilot to train” and “Rendering and dataset export work without it”. File > Export > Splat Training Dataset exports the rendered views for Postshot, LichtFeld Studio and other trainers.
