Three Times Slower FPS than the original implementation

[yoonsota]

Hello,
I sincerely appreciate you for providing this library.

I am using gsplat for development and noticed that for smaller scenes (e.g., D-NeRF), gsplat is about three times slower in forward processing compared to the original diff-gaussian-rasterization. This significantly reduces the FPS. Is this behavior expected, or could it be due to a configuration issue on my part?
