A10 7850K OC and MSI Oc GTX760

[plank225]

Im kinda new to computer gaming am hoping to get some real help. I recently bought this gaming rig from someone and I play dayz, h1z1, battlefield etc. Now recently I purchased watch dogs and it ran ok until I started moving the mouse fast and got serious screen lag and downloaded Tera and got the same thing both of these games seemed to use about 80% of my memory on my computer. Now this computer was overclocked when I got it and need some tips to see what I can do to improve performance I have searched everywhere but no avail.

A10 7850K with r7 Oc 4.5 ghz

Watch dogs - turn down the details and make sure you have the latest patch, that game is a nightmare

Tera - this game will always give AMD processors a bit of trouble

Ok so I apoligize I have never used forums just looked for help but then maybe you can please help with this. When I play watch dogs I know it can run on my system ive watched youtube videos with same gpu and apu and they played fine my issue is watch dogs seems to run 80-90% of my computer memory when playing as well does tera that usually not normal and trying to figure out what to do cause a few people said they wouldnt over clock there computer so what should I try??? Basically what happens is when I Make fast movments with my mouse its not mouse lag but the frames will drop down to about 7fps with both tera and watch dogs.
