New to Vray - Grainy reflections help

Sorry my first post here has to be me asking for help guys, but I need some help quick so thanks ahead of time. I've been working in 3DS Max for a long time using mental ray and always getting some good renderings. My job has asked me to move up into Vray now which I was able to do pretty successfully except for one small issue. All of the reflections on the wood and other surfaces are very grainy! I have done a lot of searching on the interwebz on this topic and have seen a decent amount of people having the same issue, only thing is they either never post their solutions after being helped or they are using Vray terminology that I am just not familiar enough with. I have attached a photo here so that you can see exactly what I am talking about. The biggest problem areas are on the floor (right side) and around the picture frame (left side). 150255 As far as settings, most of them have been left at default except for a few that many tutorials said to change, I'll do my best to list off what might help to diagnose this... 1) GI is enabled 2) Primary engine = Irradiance map @ 6.0 3) Secondary = Brute force @ 1.0 4) Global DMC set to use local, subs multiplier = 1 / min samples = 16 5) Neither the floor or picture frame materials have any kind of bump or displacement on them 6) In all the lights I have changed the subdivisions to 12 I think those are the major changes I have made in an attempt to fix this. I also just noticed that if I render the image at a larger pixel dimension the problem gets worse. Current render is at 1024 x 768 Thanks again folks
