if you change the indirect map built in presets from High to meduim abviously the time will dicrease a lot
you have used HDRI but i cant see it in environment
my self i havent used such lightining system , maybe you are doing it in the right way
but i always try it with vray sky and a vray light but the vray light should be dark

hope it helps

sorry i dont know much about vray, all i know is that it often takes a lot of time, my renders of simple scenes takes around 4h-8h.

you can take the subdivs under irradianc map down to 30, becaus the scene will not use more than that. and the light cache can be putt down to 1000 from 2000.
i dont think it will make a big differenc on the quality.
dissplace ment often takes long time, but there i dont know the settings, just take a look at it.

you have a very shiny picture, fallof is a bad ass on rendering time, so if your scene is full of that you might turn some of or somthing.

if you turn down the sampeling on the lights that will alsow speed up your rendering time, but lower the bouncing and rays the light will break up in when hitting ground.

i will take a look at you uploaded files tomorrow and see if i can find anything from them

cheers and good luck

thax for the info......now the problem here with vray setting i think. i changed the material of the body to asimple one, but still the render so slow.changed the cache and also the subdivs. still realy bad. well...i think nothing to do with it....its my pc.
the file should work with vray..so you cannot render it.
anyway thx for help......gonna change the scene lights and see what happens

try rendering it without displacement and check your adaptive rQMC image sampler's max samples. i think 100 is more than enough try 8 or 10
