Hi,

• We test our method on a single NVIDIA RTX3090 GPU.

• The comparison of rendering speed on the DNeRF dataset with 800*800 resolution is as the following table:

Method	3D-GS	4D-GS	Baseline	Ours
FPS	298.5	145.8	113.3	295.4

Baseline is our method without sparse control points and with per-Gaussian motion prediction.
Notice that our method uses cached NN information and does not need KNN queries. The cost of MLP prediction for each sparse control point is very little.
