Renderings too grainy

I think that you should increase shadow subdivision of the VRay sun, this should reduce the grainy border between the shadow and direct light. Normally it is 3 i think. For environmental light is better VRay dome light for using with VRay sun. And also a classical VRay light for sky-portals should get rid of the splotchy walls.

Placing a skyportal where light comes in should remove problems with noise (also will increase render time).

I found it very useful to spend some time exploring the Universal V-Ray Settings. Check it out, then optimize.

Your V-Ray::Adaptive DMC image sampler is set to "Use DMC sampler threshold"
On the V-Ray::DMC Sampler, the "Noise threshold" is set to 0.01, set it to 0.005
Normaly, Max Exposure Control is not used with Vray if you use the Vray Physical
Camera; however, whatever works for you...
I don't see the Sun described, are you just lighting with the environment? VraySun Parameters?
