Hands, or anything moving fast too close to you, is indeed where spacewarp struggles.
Game latency is just your frame time ( time to render 1 frame on PC ). You're not quite able to maintain 90fps ( 11.1ms ), which is why spacewarp (auto) is kicking in.
Decoding is a bit high because you have video buffering enabled; disabling it decreases latency, but may introduce stutters. Generally leave on.
Decoding latency might be brought down by lowering bitrate or using h264 instead, but there's always going to be a tradeoff
