The easiest way would be to go into the VRay settings set the color threshold to something absurdly low (e.g. 0.0001 or lower) and up the max samples to 100. The result will be noise free, but will take ages to render.

The smart way is to render out the lighting and reflection passes to see what needs fixing. Noisy reflections = increase subdivs on the materials. Noisy shadows = increase subdivs on the lights.

Once you've done that you can try fiddling with the sample rate/color threshold values in your VRay settings to optimize render times.

put portal lights in front of the windows so they let more light come in.

to reduce noise decrease the threshold and increase the max subdivisions in the "Antialiasing" tab in Vray settings. I used to go with 15 subdivs and 0.001 threshold, but the render times got too long and i started rendering in a larger resolution with 32 subdivs and 0.01 threshold and then scale the picture down so it looks less noisy.

your picture isn't that noisy tho, it looks fine to me

Thanks for the little tips. Made some adjustments and it looks x10 better
