Witcher 3 Performance Problems on PC?

I just got the game and am running it on a Lenovo X315. The main menu screen looks BEAUTIFUL and flows very very nicely. But when i get into the actual game, it slows down. The reaction time between my controls and the game are slower, its lagging pretty much. And the voices are very off from the character's mouths when they speak. I know that my computer should be able to run this so i'm not sure what's wrong. I've been messing with the settings all day and can't make it run nicely without it turning the graphics to complete crap.

Computer Specs: AMD A8-7600 3.1 GHz Processor
8 GB SO-DIMM DDR3 RAM
1 TB 7200 rpm Hard Drive, 8 GB Solid State Drive
AMD Radeon R9 360 Graphics

If you have any tips on how to make this run better it would be greatly appreciated thank you.

Full size ATX system probably is DIMM rather than SO-DIMM of laptops.
Unfortunately, people look at system descriptions and believe the words rather than understanding specifications.
An R9 360 is not a great graphics card.
It is below the recommended minimum for the game, and specs say lowest settings on a 1080p display for the game

To game designer, 81% of minimum CPU and 69% of minimum Graphics processing.
You can do much better with custom and semi-custom tower pcs than brand name ones.
The card ranks somewhere around #80 on this table

Hairworks OFF as a start. On 1920x1080 displays it should play lowest settings.
An R9 360 is similar to R7 360, but has been set to run at lower power.
I believe they used a very efficient power supply but at a very low 280 watts that limits graphics card upgrades without changing the power supply. Known brand systems publish very little in specification details.
An A8-7600 is also a poor choice. The CPU is just adequate, has no upgrade really, and a graphics that is unused. If the system is set to dual graphics, you need to get it to use only the R9 360 via control panel. Also get to the latest driver's level.

As strong appearing as the computer looks, it is not a great performance, but that is true in HPs, Dells, etc.
