Mouse feels wrong what is the problem?

Hi Guys,

 

So my post is going to be about an ongoing technical issue regarding mouse input and possibly other input devices (controllers).

I have been PC gaming since around 2012 I have always mainly played first person shooters at the time Arma 2, Black Ops 2, Battlefield 3.

 

So back then I had a premade PC with an AMD A8-5500 APU and a HD6670, I was loving PC gaming back then I could jump into matches and not have to worry about changing sensitivities or any other setitngs it all felt great.

After a while of playing I ventured into Planetside 2 and some more demanding games, I noticed that my hardware was limiting FPS performance so I decided to upgrade my GPU

to an HD 7850 after a short while I realised something called Bottlenecking. I had a very basic mouse at the time which gave out so I purchased a RAT3 mouse I noticed an improvement in precision instantly.

 

The time came to upgrade my CPU to a 8350, these upgrades were in the space of a year. so I can rougly remember loading up black ops 3 and noticed I was struggling to aim something felt different, 

I ignored it for a short while but noticed that every game I played felt odd. The problem is to do with the feel of the mouse feeling slightly odd in correlation to my movements it doesn't feel like input lag so much but just a lack of precision.

 

So what have I tried since then:

5-6 Gaming Mice Optical / Laser + 1 Wireless

2 Different PSU's

2 Different Monitor's

Different OS Windows 7,8,10 + Linux Ubuntu

3 Different GPU's

3 Different Motherboards

 

So out of all of those the only two pieces of hardware are the CPU or the RAM, I currently have 8GB DDR3 1600MhZ ram with a stock 8350, could it be a defect piece of hardware. When I upgraded my ram from the 4GB to my new 8GB setup back when everything felt right

and my PC felt really fast but since then my PC does feel a lot slower even with a much better CPU.

Is it either a new CPU + RAM combo or is there anything I can try in the mean time which might solve it.

 

A lot of people have been having the issue with black ops 3 aim, with certain lag and poor accuracy it feels like that for me but on everything.
