I don’t know exactly if it really is a matter of V-ray or I’m doing something real silly which is giving me this flickering rendering result… Hope you guys could help me out…

Flickering ploblem in rendering -Vray
u must increase the settings of Irradiance Map. Try using Medium or High Animation presets
we switched to using:
Primary bounce:Brute Force and secondary Bounce:light catch Use adaptive dmc for anti aliasing.
It works pretty well for most situations, and this way you don’t have to deal with iradiance maps
I don’t know haw many lights are in your scene but you probably have to ad a few inside you stair case so there is more sampling
Thanxx dementol and HeadSmell for your replies… I tried changing settings with irradiance map…but that didn’t helped… also when I switched to brute force and light cache there was no change but when I did adaptive dmc…it gave me this result 
If it’s just the camera moving, you can create a single irradiance map and render the final using the "from file setting, as described here:
this problem did stopped somehow…but now its coming again… I m not sure where the problem lies… even i increase the quality but here’s the settings of v-ray"
