FSX-MS FSX - Losing FPS

[vic89 0]

I am new to this forum and was hoping I can get some feedback/help on my current FSX configuration. I apologize if I have posted this in the wrong section. 

 

Below are my specs 

 

Intel Core i7-4790K CPU @ 4.00 GHZ

16.0GB Dual-Channel DDR3 @ 799MHz

4095MB NVIDIA GeForce GTX 970

 

 

*FSX is installed on a SSD of its own (128 gb) 

 

Some of the third-party addons I am using ->  

REX TEXTURES 4 + Soft Clouds 

Ultimate Traffic 2

Airbus X Extended

 

 

 

My FSX.Config file -> http://pastebin.com/DZnnzTXt

 

I am getting 20-25 fps with quite a bit of stutter. I plan on removing FSX completely and slowly start configuring it again to see where the bottleneck is

Your AffinityMask is for HT=ON, you have got hyperthreading on?
