Now I've never messed with any of these but would any of the options listed in that field help with high movement games? Also what does "profile" specifically do?
 
They change the encoder's parameters for specific content and devices. Both of these can be left at default (none).
 
Personally i use only like this:

For Quality

CPU Preset= Veryfast
Profile=main
Tune=film

For Performance

CPU Preset= Veryfast
Profile=main
Tune=fastdecode or zerolatency

And work very well for me with a very very poor system pc. I am streaming from a laptop from 2009 (HP DV5) , i stream in 360p 30fps and its work very well, my processor its used like 45%.

This is what the modes do:

  • film – intended for high-bitrate/high-quality movie content. Lower deblocking is used here.
  • animation – intended for cartoons, etc., where deblocking is boosted to compensate for larger, flat areas. More reference frames are used.
  • grain – this should be used for material that is already grainy. Here, the grain won't be filtered out as much.
  • stillimage – like the name says, it optimizes for still image encoding by lowering the deblocking filter.
  • psnr and ssim – these are debugging modes to optimize for good PSNR and SSIM values only. Better metrics don't necessarily mean better quality though.
  • fastdecode – disables CABAC and the in-loop deblocking filter to allow for faster decoding on devices with lower computational power.
  • zerolatency – optimization for fast encoding and low latency streaming
