FPS style mouse + keyboard support - performance issues

[Mr160h]

Hi,

I've implemented FPS style mouse + keyboard support through actions¹, but I get a large drop in FPS when pressing keys or looking around. I think it's because I can only pass one input action to the environment for each step. For example: if the player presses forward and right at the same time I will have to call controller.step() twice and it will render two frames when only one should be needed².

This also looks very jittery at low fps (~30FPS and below) due to it rendering the intermediate frame when moving diagonally.

Are there any ways to implement FPS style mouse + keyboard support that's more performant?

I feel like I'm missing something because the web demo is performing just fine with FPS style input, but I can't figure out what it's doing differently except for perhaps having some custom Unity code?

Footnotes

1. I'd be happy if it was possible to use an agentMode that read keyboard+mouse input directly from within Unity, but I haven't found support for that. ↩

2. It looks like the environment only supports one movement action per frame due to it doing a yield return new WaitForEndOfFrame() between each movement action it receives from the FIFO server (link). ↩

I managed to work around this issue by using the TeleportFull action. The performance and user experience is better now.
