My rig is dieing running unreal 4 lowest settings

Windows 7 64bit
Intel(R) Core™ i7-3770 CPU @ 3.40GHz (8 CPUs), ~3.4GHz
8192MB RAM
DirectX 11
AMD Radeon™ HD 7450

Above is my spec, now when I open unreal even on lowest visual settings, I have terrible screen tear and FPS, my GPU drivers are up to date as far as I know…anyone ran into this issue :S

Top of my mind with that rig is that somehow the Intel chip is running UE4 and not your AMD. However I cannot think of how to fix it right now…

The video card looks seriously under-powered.

Your card is not really made for this kind of resource hungry Engine, the best is to upgrade your current graphics card to a more suitable card for example a HD 7850 or GTX 660 if you can’t afford a new card off the bat try looking for second hand cards the GTX 580 and GTX670 should be going for pretty cheap right now.
